This profile of Walter Isenberg, co-founder and CEO of Sage Hospitality, is based on an interview by Hospitality Daily founder and publisher Josiah Mackenzie.

When Walter Isenberg was 14 years old, washing dishes at a Kansas City country club, a maître d' without a high school diploma told him something that would change his life.

"You love this business?" Carlos Peña asked.

Walter said he did.

"Well, you need to go to Cornell University."

Walter asked where that was.

"New York," Carlos said. He didn't mention Ithaca.

That conversation—between a teenage dishwasher and a Mexican immigrant maître d'—eventually led to a letter from one of the most powerful hoteliers in America, a Cornell education, and 40 years later, Sage Hospitality: a company that saved Denver's Union Station, pioneered the concept of story-driven independent hotels, and helped define what modern urban renewal could look like.

But here's what Walter remembers most about Carlos Peña: he got him out of the dish pit not because he was talented, but because he saw something. Potential. Care. A kid who loved the work.

"He inspired me," Walter told me. "And it's kind of been my inspiration through my career."

This is a story about mentorship, but more than that, it's about what happens when you build a hospitality company on a simple idea that most CEOs give lip service to but Walter actually organized his entire business around: the job of a hospitality leader is enriching lives. Not just guests' lives. Everyone's lives.

The Dishwasher, the Maître D', and the Cornell Letter

Walter grew up in Kansas City. At 14, he answered an ad in the newspaper and got a job washing dishes at a country club. "It's where I fell in love with the business," he said.

Carlos Peña worked as the maître d' in the dining room. He took an interest in the teenage dishwasher. "At 14 years old, he inspired me and it got me out of the dish pit into the dining room, and then really helped me along the way."

After a few years, Carlos told Walter about Cornell's hotel school—the best in the world. Then he did something extraordinary: he introduced Walter to Phil Pistilli, a prominent hotelier in Kansas City who was chair of Cornell's hotel school alumni organization and chair of the American Hotel Lodging Association.

Phil Pistilli wrote Walter a letter of recommendation.

"Thank God for that letter," Walter told me, "because my SATs were not getting me into Cornell."

The letter changed everything. Not just because it got him into Cornell, but because of what Phil Postelli taught him about what hospitality leadership actually means.

What Phil Pistilli Showed Walter at 5 AM

Phil Pistilli ran a 400-room hotel in Kansas City. Walter calls him "a great, great hotel man."

Every morning, Phil arrived at his hotel at 5 AM. Not to review reports. Not to check the books. To see the night auditor finishing their shift.

The loneliest role in the hotel. The least visible work. The person who would go home when everyone else was arriving.

Phil made sure they knew someone saw their work.

Then he'd walk through the coffee shop. Not the grand lobby. The coffee shop, where locals gathered for breakfast. "He walked through there every morning and spent a lot of time with the customers."

By the time most general managers were getting to the office, Phil had already checked in with housekeeping. All of them. "He knew all his housekeepers and this was a big hotel. Four hundred rooms."

One day, Phil asked Walter a question he never forgot:

"Walter, do you know what a housekeeper has to look forward to every single day?"

Walter didn't know.

"Sixteen dirty toilets."

"It's so true that we should never lose sight of the job that these people do," Walter said. "It's important to our success and that runs through the entire organization. Whether it's a dishwasher, a night auditor, front desk associate, we have to make sure that they have a great environment to work in, that they know that we care for them."

This became the foundation of everything Walter would build at Sage Hospitality.

Not: How do we maximize labor efficiency?

But: How do we enrich the lives of people whose work is essential but often invisible?

Building Sage Hospitality on "Enrich Lives"

Walter co-founded Sage Hospitality in 1984 with partner Zack Neumeyer. They didn't have money. They volunteered their time. As they got hotels, they donated gift certificates to school auctions. "It's just been central to who we are and how we live," Walter said.

Today, Sage's purpose is explicit: "Enrich lives one experience at a time."

But here's what's different: most hospitality companies say this means enriching guests' lives. Walter says it means enriching associates' lives first.

"We talk about enriching lives of our customers and our guests, but we also talk from a leadership perspective about enriching the lives of our associates. How do we get up every day to do something that will help enrich their lives?"

It's not a slogan. It's an operating principle.

Recently, a new front office manager joined Sage and went through their cultural immersion program. She sent Walter an email about the experience.

Walter wrote back: "Thanks for enriching my life today with this email."

Then he forwarded it to the people and culture team who ran the program: "Thank you for enriching my life and her life today."

"That goes on all the time in our organization," Walter said. "It's at our core, it's our why, it's our purpose."

The Cultural Immersion Program: Onboarding for Purpose

Most hotel companies onboard new managers with paperwork and policy manuals. Maybe a video about core values.

Sage does something different.

Every new leader—front office managers, executive committee members at properties—gets flown to corporate office quarterly for cultural immersion. Not a day. Not a video. They physically come to Denver.

"They are put through a program about our history, our culture, and then they get to meet leaders from the organization, from our executive committee, so they really understand what we do and who the leaders are within the organization," Walter explained.

The program covers the "what" and the "who." But more importantly, the "how"—the core values and purpose that drive everything.

"That is an investment that we make. We do it quarterly. I'm usually there," Walter said.

Notice that: the CEO of a 40-year-old company with properties across the country is usually personally present at quarterly onboarding for front office managers.

"It's a robust program and one that we believe is really critical for new people coming into our company to really understand the core of the organization and our culture."

The sequence matters: Purpose before operations. Culture before execution.

You learn the why before the how. You understand what Sage stands for before you learn the systems and processes.

The Martini, the Cocktail Napkin, and Dana Crawford

In the late 1980s, Walter's wife started working as a PBX operator at the Oxford Hotel—Denver's oldest hotel, built in 1891. She quickly became front office manager.

The Oxford had an incredible story. Dana Crawford—Colorado's most significant historic preservationist—had bought it in the early 1980s when it was a flophouse and turned it into a beautiful luxury independent hotel in Lower Downtown Denver, a neighborhood that in the eighties "was just low," Walter said.

But in 1986, the hotel went bankrupt. A Seattle lumber company bought it, brought in management, and pushed Dana down to limited partner. She had no control.

Walter's wife would bring home the financial statements. "This is really bad. I think this company isn't honest. You need to meet Dana."

So Walter met Dana Crawford at the Cruise Room.

The Cruise Room is a bar inside the Oxford—a little art deco speakeasy fashioned after a bar on the Queen Mary. It opened the day Prohibition was repealed. Jukebox, martinis, Manhattans. "It's just a cool spot," Walter said.

Over a martini, Walter told Dana: "We can turn this place around."

Dana had heard that before.

Walter wrote a number on a cocktail napkin. "If we can't hit that NOI, you can fire us. Let's figure out how to get back control of the asset."

They bought the general partner interest from Weyerhaeuser, threw the hotel back into bankruptcy—Dana affectionately called it "Chapter 22," their second Chapter 11—and became the manager in 1990.

Walter and Dana were partners for 35 years at the Oxford Hotel.

What Dana Crawford Taught Him About Story

When Walter and his team took over the Oxford in 1990, they didn't know anything about historic preservation. They didn't really know anything about independent hotels. It was Sage's first equity deal.

"What Dana taught us was that if your hotel has a great story, guests will be attracted to it," Walter said.

This was 1990. Before "boutique hotels" were a category. Before Instagram. Before "authentic" became a marketing buzzword.

Dana was way ahead of her time.

"You think about today," Walter said. "That's really what a lot of the great hotels, whether they're new build or historic, you wanna have a great story. The guests are moving away from branded hotels—it doesn't mean there's not a good spot for branded hotels—but you think about where the interesting places that people are going: independent or soft branded hotels. It's where customers are attracted to, particularly leisure."

Dana's insight became central to how Sage develops every property: Start with story.

Sage Studio: How to Build Story Into Every Hotel Project

To operationalize Dana's insight, Walter created Sage Studio—an in-house team that does all branding and placemaking work for Sage properties.

"They really look at the history of the place," Walter explained. "Where it sits in the community. Then really thinking about the customer. How's the property gonna be positioned? Who's the customer we're trying to attract?"

Then they identify a muse for the project. "That muse may not be public, but it's what we do to create the story."

They use the muse in hiring, onboarding, training, and the types of activations they program. And it works for both historic adaptive reuse and new construction.

Example: Dairy Block in Denver. A full city block that happened to have a few historic buildings—one was a dairy, another was a lumberyard.

The muse? A collection of makers.

"You think about a lumberyard—people are building things. A dairy, they were taking the cow's milk and pasteurizing it. They were making it drinkable," Walter said. "As you look at the hotel at Dairy Block called the Maven, a maven is an expert at their craft."

They curated the retail to fit the story: a local jeweler who makes her own jewelry, a distiller, a wine maker, a beer producer—all local to Colorado.

"That story isn't like—I don't know that a guest would come in here and go, 'Oh my God, this is a group of makers'—but they feel something and it's authentic," Walter said. "We fundamentally believe that consumers are very smart and they know the difference between something that's authentic and inauthentic."

Saving Denver's Union Station

The story that means the most to Walter is Denver's Union Station.

When Sage got awarded the right to redevelop it, they went through probably 15 public meetings before winning the deal. The Regional Transportation District board had to vote three times before the CEO got the unanimous approval he wanted.

"This was a long, drawn-out process," Walter said.

After winning, they did neighborhood focus groups. "We asked people, what do you wanna see?"

The answer became their north star: "We want the Great Hall of Union Station to be Denver's living room."

A place where people could gather, enjoy a cocktail, enjoy food, enjoy coffee, and enjoy friends. A community gathering place.

Today, Union Station hosts about 250 events a year. Some simple—a musician playing in the Great Hall. Some bigger—"Boo Station" on Halloween, where hundreds of kids in costume trick-or-treat at the retailers. A big tree lighting ceremony at Christmas with Santa there every Saturday, lines out the door.

During the Nuggets’ playoffs, Union Station is the official watch party. "The place is decked out with Nugget stuff," Walter said.

This idea—the town square, the heartbeat, the gathering place—became central to how Sage thinks about urban renewal.

And at the heart of it: the hotel named after Dana Crawford.

The Crawford.

"We honored her by naming the hotel after her," Walter said. "We were glad that she got to see that and live with that for over 10 years as a real honor to her."

Dana Crawford passed away on January 23rd at age 93. But her insight—that story attracts guests, that historic preservation matters, that cities need gathering places—lives on in every Sage property.

Why Hospitality Is the Best Catalyst for Urban Renewal

I asked Walter if hospitality can be a catalyst for urban renewal.

"Hospitality might be one of the best catalysts for renewal," he said. "And the reason I believe that is we're a 24/7 business and we have new people coming in all the time and they want to experience different things."

Residential is important—people living downtown help make it a 24/7 city. But hospitality brings new people who experience the place and share it.

"You think about where we are, particularly the way things happen today with social media," Walter said. "We have that big wooden hand in the Maven lobby. That thing has been Instagrammed a million times. People who come to visit go, 'Wow, this is really cool. I'm gonna post this.' I'm from San Francisco, but all of a sudden, your post is this endorsement of our place. Someone might look at it and go, 'Wow, that's really interesting. I haven't been to Denver in a while. Maybe I'll go.'"

Hospitality doesn't just serve visitors. It creates ambassadors.

The "Plane Seat Test": A Strategy for Local Authenticity

Walter has a simple test for whether a Sage project is working:

"If you and I were sitting next to each other on a plane and I was flying to San Francisco, and I said, 'I've never been to San Francisco, what should I go see? Where should I go?' We wanna be on that list."

Not the corporate marketing list. The locals’ list.

"If I'm sitting next to you on the plane and you're coming to Denver and I'm a local, I would say, 'Hey, you gotta go to Larimer Square. You gotta go to Union Station, you gotta go to Dairy Block.'" Walter said. "We wanna be on that list for the local."

The strategy: "In order to do that, your project needs to be beloved by locals, and if you get that, visitors will come."

What 40 Years Taught Walter About Giving Back

Walter and his partner have been involved in their communities since day one. Not because it was strategic. Because "it's just been central to kind of who we are and how we live."

"I believe that you should go into giving back for all the right reasons," Walter said. "What I would tell you is that it comes back to you in many, many ways."

He serves on the executive committee of the American Hotel Lodging Association. But he says the real value—the outsized value—is engaging with people outside the industry.

"The diversity of knowledge that you gain from sitting next to a banker, a lawyer, an architect, whatever the business might be, it has really been super impactful to me, and I've learned so much. The benefits are there if you're willing to invest the time."

The relationships built through nonprofit boards lead to business relationships, yes. But more than that, they provide completely different perspectives that shape how you think.

The 800-Person Reunion

In March 2024, Sage celebrated its 40th anniversary with a weekend of events. One night was an alumni party.

They reached out to people who had worked at Sage over the decades. People from the eighties who had moved on to other things.

Eight hundred people showed up.

"It was just so heartwarming to see people who had worked for us back in the eighties who came back and had gone on to do other things," Walter said. "But the fact that they showed up meant that we somehow really had touched their life."

That's when I asked him: What do you hope your legacy is 50 years from now?

"I would want people to say that I changed their life," Walter said. "I think about people that have worked for our company. We've got a lot of alumni and I am most proud of those people who have gone on to do great things. Some starting their own company."

Not the buildings. Not the hotels. Not even the neighborhoods transformed.

The lives changed. The people who grew. The careers launched.

"That to me is the legacy," Walter said.

Paying It Forward

Walter still gets emails from people—usually a friend's son or daughter asking about a career in hospitality, wanting an internship, or looking for advice.

"I always reach out to those young people," Walter told me. "Because it happened to me."

Carlos Peña saw something in a 14-year-old dishwasher. He connected him to Phil Postelli. Phil wrote a letter that changed everything.

"I think paying it forward is important," Walter said.

Forty years after Carlos Peña handed him an opportunity, Walter's still doing the same thing. Still getting people out of the dish pit. Still believing that mentorship matters. Still responding to every inquiry because someone did that for him.

Looking Ahead: Where the Opportunities Are

When we talked, cities like San Francisco, Portland, and LA were still recovering from pandemic challenges. Walter sees opportunity.

"The cities that have suffered the most—I think are where the opportunities are gonna be," he said. "I am a passionate believer in urban core. I think that we need great cities. They're the heartbeat of a region."

He pointed to Denver's recovery in the 1980s. When Walter moved there in 1984, Denver was very depressed. Oil went from $40 a barrel to $8 a barrel. Downtown office vacancy hit 40%.

"But the political leadership and the civic leadership came together and said, we are going to fix this," Walter said. "It took a decade, but Denver came out of it and by the late nineties was really booming."

He has the same confidence in San Francisco, Portland, and LA. "The changes that were necessary are afoot. I see that happening."

It's going to take time. "These problems didn't occur overnight. They're not gonna get fixed overnight. But if people lean in and really do the right thing and come together, I think it will happen."

Walter's been at this for 40 years. He's seen cycles. He's seen cities struggle and come back. He's seen what works: great hotels, great restaurants, vibrant retail, people living downtown, energy.

And story. Always story.

The Through Line

From the dish pit at 14 to CEO at 60, there's one through line in Walter Isenberg's career: people.

Carlos Peña, who saw potential in a teenage dishwasher and connected him to the right people.

Phil Pistilli, who taught him that a housekeeper looks forward to 16 dirty toilets every day—and that great leaders never forget that.

Dana Crawford, who showed him that if your hotel has a great story, guests will be attracted to it.

The 800 alumni who showed up to celebrate 40 years because Sage had somehow touched their lives.

The new front office manager who sent an email about cultural immersion that enriched Walter's day.

"Enrich lives one experience at a time" isn't marketing language for Walter. It's the organizing principle of a 40-year career.

"We wouldn't be here if our housekeepers didn't get up every day to come in," Walter told me, echoing Phil Pistilli from decades ago. "That runs through the entire organization. Whether it's a dishwasher, a night auditor, front desk associate, we have to make sure they have a great environment to work in, that they know that we care for them."

Not as strategy. As purpose.

When Carlos Peña told that 14-year-old dishwasher "You need to go to Cornell University," he probably didn't think much about the conversation.

But that moment changed everything. Not just for Walter, but for everyone whose life he's enriched since.

The front office manager who sent that email. The hundreds of Sage employees who've grown into leaders. The guests at The Crawford who experience Dana's legacy. The neighborhoods transformed. The alumni who showed up because it mattered.

And the kid whose parent's friend emails Walter asking for career advice—and who gets a response.

Forty years after Carlos Peña handed him an opportunity, Walter's still getting people out of the dish pit.

Still believing that the job is enriching lives.

Frequently Asked Questions

Q: How did Walter Isenberg start Sage Hospitality?

A: Walter co-founded Sage Hospitality in 1984 with partner Zack Neumeyer. His path to hospitality leadership began at age 14 when he worked as a dishwasher at a Kansas City country club, where he was mentored by Carlos Peña, a maître d' who inspired him to attend Cornell University's hotel school. Carlos connected Walter to Phil Pistilli, a prominent hotelier who wrote the letter of recommendation that got Walter into Cornell, launching his career in hospitality.

Q: What is the "Sage Studio" approach?

A: Sage Studio is an in-house branding and placemaking team that Walter created to operationalize the insight he learned from Dana Crawford—that hotels with great stories attract guests. For every project, Sage Studio identifies a "muse" that guides the narrative, design, hiring, training, and community programming. This muse may not be publicly visible, but guests feel its authenticity. For example, Dairy Block's muse is "a collection of makers," inspired by the historic dairy and lumberyard buildings on the site.

Q: Who is Dana Crawford?

A: Dana Crawford (1933-2025) was Colorado's most significant historic preservationist. In the 1960s, when cities favored urban renewal through demolition, Dana literally laid in front of bulldozers to save historic buildings. She was a pioneering female developer who saved Denver's Larimer Square—the first block of buildings built in downtown Denver—and later the Oxford Hotel, Denver's oldest hotel built in 1891. She partnered with Walter Isenberg for 35 years, teaching him that "if your hotel has a great story, guests will be attracted to it"—a principle that became central to Sage's development approach. Walter honored her by naming The Crawford Hotel at Union Station after her.
