We are heartbroken to share that
Mark Hyatt passed away naturally on March 14th, 2026 at 7:30 AM
after a 20-month war with pancreatic cancer.
On March 11, 2026, Mark decided his battle was over
and he wanted to discontinue treatment.
Plans were being made for him to pass with dignity within the week,
on his own terms, but the universe stepped in to change the course.
March 14th, the day he passed, was Olivia’s birthday
and we think he couldn’t bear to spend another
one of her birthdays without her.
He left us just after sunrise, surrounded by his sons
Sam and Wade, his sister Terra, and his friends
and caregivers Tom, Stephanie, Leo and Kristof.
Our hearts are shattered, but we take comfort that he is
finally at peace after his heroic battle.
Mark Hyatt was the sun in everyone's sky,
and his sunset came too soon.

Marquis Edward Hyatt
Born in Long Beach, CA.
OCTOBER 2nd, 1969
Mark was the sun in everyone’s sky.
Born on October 2, 1969, to Don and Mary Lee Hyatt, Mark grew into a presence people gravitated toward, like the sun. He passed just after sunrise on March 14, 2026, the birthday of his beloved late wife, Olivia, as if he had waited for the sun to rise on her day, a moment that feels like something only Mark could have orchestrated.
Olivia, the love of his life, passed in 2021. They were perfectly matched in a way that people spend lifetimes searching for, and after losing her, Mark was never quite the same. Still, he carried her with him in everything he did, in the way he loved, in the way he showed up, and in the light he continued to shine on others.
He leaves behind his mother, Mary Lee, whose quiet strength and enduring love were a constant in his life, his sister, Terra, who was a deeply important part of his life, and his sons, Sam (22) and Wade (18), who were the center of his vast and vibrant world.
Mark’s light shone brightest for his sons. There was a sparkle in his eye reserved just for them, a kind of love that was unmistakable. Everything Mark was, everything he built, everything he gave, always came back to them.
Mark was a legend in every world he touched. In real estate development and finance, he built deals, relationships, and a reputation that carried weight everywhere he went. But his real legacy wasn’t just what he built, it was who he brought along with him. Mark didn’t meet strangers; he made lifelong friends, sometimes in a single conversation. He was generous in a way that made people feel seen. He was hilarious in a way that made rooms lighter. And he somehow knew every word to every song ever written, never missing a moment to turn life into something worth singing about. Mark lived by a simple rule he shared often: add value. And he did, everywhere, for everyone, all the time. To be with Mark was to feel something rare. It was like stepping into sunlight after a long time in the dark. Warm, energizing, impossible to ignore. He made people feel better just by being there. Mark leaves behind a life that cannot be measured in years, deals, or accomplishments, but in laughter, loyalty, and the countless lives he brightened. And though he is gone, the warmth he gave doesn’t go with him. It stays with all of us who were lucky enough to stand in his light, a light that will continue to shine long after the sun has set, just as he now stands again beside Olivia, where he always belonged.

It truly brings a lump to my throat to say these words, as I am not a relative of Olivia or Mark. However, I do consider myself part of the family, because I met them eight years ago. I came to know these two wonderful people, who were Olivia and who was Mark. Now, both of them are together in heaven, living their life as they did here. I send a sincere hug to both of you, Mark and Olivia. Truly, thank you for giving me the opportunity to work at your home in Newport Beach. I am deeply grateful. Few employers ever treated me with the same kindness as you did. Thank you. Rest in peace, and you will be deeply missed.
So sorry to hear of Mark's passing 😢 He was a client that I worked with and conversations with him about our industry were always enlightening. These photos were taken in Vegas a couple of years ago during a conference in Vegas. Great memories of a great person. May God Bless and comfort you Mark.
Mark, I will miss your incredible smile that would light up a room. I will miss your big hugs and loving energy! Always so generous and loved being around your friends. Mark, you were one of a kind a loyal friend and lived life to the fullest. Go be with Olivia and rest in peace and power. Love you!
I met Mark and Olivia in 2013. I was blessed with the opportunity to spend a lot of time traveling with them over the years. They had a gift of building the most eclectic group of people to befriend. They covered every angle from all walks of life and every friendship way true, honest and genuine. We were all so fortunate to be part of it.
Mark was loyal with absolute conviction. He put ultimate trust in those around him and somehow it manifested great things from all directions. I saw it both with friends and in business.
While our time with both of them was too short, we can find comfort knowing that they both lived every single second at 100 with their foot on the gas.
I miss you both so much,
Cody
Mark was a great neighbor, friend and a good human. Mark and olivia were always trying to make you comfortable and happy. Boy were they good at that! Mark will be missed terribly We loved him! RIP
Mark was my closest guy friend in high school. We did everything together and got into a lot of trouble together. I remember afternoons at Sizzler trying to see who could eat the most shrimp. It was supposed to be all you can eat, but we got kicked out every single time for eating too much! He spent a lot of time with my family and my parents loved him. Mark was always so nice to everyone. The trips to Rosarito Beach were so much fun and he sure loved his cars. He was a heck of an athlete and as one of the boys I could really relate to the time he spent getting better at his sports. He once made me sit in his living room one night to try and convince me to like Led Zeppelin. (It never worked. I was too "shape".) He could argue about absolutely anything, regardless of how mundane it was. We had some great conversations and I loved that he challenged everyone he spoke to. We haven't kept in touch that much as adults, but I have seen the positive effect he has had on everyone around him. Losing him is so tragic. There will never be anyone like him.
I learned a lot from Mr. Hyatt, but #1 on that list was what it means to be loyal. Once that man was on your team...there was never any going back! He made a huge impact on my life and so many other people's lives, and he did so with a smile on his face and with no desire for any credit. He was a rare example of a genuine man. I miss you, Mark.
My first encounter with Mark and Olivia was at the open house at 3915 Seashore Drive. I had just listed the property and was hosting a broker preview, with open house signs set out front. They happened to be riding by on their bikes and decided to stop in and take a look. They were smiling, relaxed, and seemed completely nonchalant about the home—I assumed they were just curious neighbors.
About a week later, Mark called me and told me this was his forever home on the beach. He loved the floor plan, especially the third-floor bar. During negotiations, he was all business—sharp, disciplined, and focused. Over the years, though, I got to see another side of him: fun-loving, adventurous, and full of life.
I’ll miss Mark and Olivia greatly. They were incredible neighbors on Seashore Drive.
Rest in power Amigo!
I consider myself incredibly lucky to have known Mark. There wasn’t a time I was with him when he didn’t make me laugh out loud. Mark could fit into any crowd and be instantly loved. He was intelligent beyond words and had a heart of pure gold.
I’ll never forget the fun times we shared including first dates, ski trips, Rosarito with Mr. and Mrs. H, and fight nights at the Hyatt House. My wife Nicole and I have so many great memories of fun outings with Mark. Thinking about them will always make me smile While Mark and I were closest during our college years, I was fortunate to work with him later and watch him shine in every setting. He absorbed knowledge effortlessly. He was the smartest guy I’ve ever known.
Mark made everything better,, whether it was chatting at a dive bar, a camping trip, a workout, or just hanging out on the couch. He was a great listener and always gave thoughtful advice. I’m heartbroken that the world has lost someone so special. This place simply won’t be as fun without him.
I’ll forever carry the memory of his smile, his goofy and comical ways, his brilliant mind, and his boundless energy for life. May his legacy live on, not only through his boys, but in all of us who were lucky enough to know him. Let’s honor him by giving, loving, and making the world a little brighter just as he did.
I’ll miss you, Hyatt, but I know I’ll see you again someday. Until then, keep making Heaven shine like no one’s watching. My love goes out to Mrs. H, your boys, and all your friends who had the privilege of knowing you. Thank you for being such an amazing person, inside and out. Rest in peace brother.
Much love always, Eric
I knew Mark from the many Waste Management Golf trips hosted by our mutual friend Lauro Garcia. My memories of Mark are his smile, and the way he always made the person he was talking to feel like he cared about what you were sharing. I did not know him well, but it was obvious that he was passionate about his friends and was always the life of any gathering. Rest in true peace Mark
