WE ARE BETTER TOGETHER.
GARY KOERNER | AIA, NCARB
PRESIDENT / SENIOR DESIGNER
Gary founded three less than a decade after graduating from Texas Tech University. His immersion into the world of market-defining, boutique properties took off with the first Rosewood Hotel, The Mansion on Turtle Creek, which he designed at the age of 27 while at Shepherd + Boyd. Gary is known for his ability to uncover signature, architectural concepts defined by the emotions and feelings of guests, staff, owners, operators and developers. Fueled by 40 years of passion for creating luxury boutique hotels and resorts, he seeks solutions to design problems that are never formulaic or trendy, but instead, bring lasting value to the marketplace through creativity. His designs have won numerous awards and are consistently ranked in the top hotel destinations of the world. Today, he further utilizes his hospitality experience in the field of senior living, developing concepts with a focus on infusing hospitality design targeted at the next generation of residents.
On any given day Gary can be found at his desk with a Diet Dr. Pepper administering sage “life-isms” such as, “Take care of your car and it will take care of you.” Outside the office, he enjoys serving on the board as a Founder of The Covenant School of Dallas, grilling out and taking the grandkids to the park. He’s also an avid soccer fan, having played as a midfielder for Texas Tech, and still plays in national tournaments around the U.S.

ROCKLAND BERG | AIA, NCARB, SAGE, ASHA
Principal/ Director of Business Development
Rockland Berg, known as “Rocky” to his friends, joined three in 1995, armed with a bachelor’s degree in architecture with an emphasis in urban design from Texas Tech University, as well as experience in interior design. A trusted and respected Principal of the firm, Rocky has led three’s senior living market space for over 25 years, expertly guiding owners and operators through the entire architectural process–from initial planning and design to the final punch list and post occupancy. Rocky is passionate and uncompromising when it comes to ensuring that senior living residences offer exceptional design for the complete well-being of each resident and guest. Nothing brings him more joy than visiting a completed project, engaging with the residents, and hearing one of them say, “I wish I had moved in sooner.”
When not speaking at conferences or convincing clients that three is the right choice for their project, Rocky can be found perfecting his swing on the golf course or competing on the tennis court. Rocky also engages in what he calls competitive vacuuming.

CARL S. EDE | AIA, LEED AP
Principal / Senior Designer
When Carl joined three in 1994, little did he know he’d found his career firm, just five years after earning a master’s degree in architecture from the University of Pennsylvania. Now, 25 years later, Carl serves as a Principal, Senior Designer and valued design mentor. His award-winning hospitality designs span the globe from swanky, single-family, Hong Kong residences and high-rise residence towers in Jakarta to luxurious resorts on the pristine beaches of Mexico, not to mention a Forbes five-star spa in Scottsdale, Arizona, and a five-star hotel in Cary, North Carolina. When three decided to begin designing senior living environments, Carl was poised to bring his knowledge of the hospitality program into the senior living sector. Two standout moments for Carl are the opening of Rosewood Mayakoba, a luxury boutique resort in the Riviera Maya, Mexico, and the challenge of creating a cost-effective senior living community in Corpus Christi, Texas, one that exudes excellent design within a coastal Texas vernacular.
If you ask Carl, he’ll tell you the secret to life is to be empathetic: give others the benefit of the doubt. When not sitting at his drawing board, Carl can be found spending time with his four (and growing) grandkids, attempting to play golf or reading an espionage novel. If you are in need of a new book, he recommends anything by Robert Ludlum.

DAVID C. FOWLER | AIA, NCARB
Principal / Senior Designer / Business Development Hospitality
David serves the firm as a Senior Designer and takes the lead in Hospitality Business Development. Born in South Carolina, he graduated from his beloved alma mater, Clemson University, in 1993 with a master’s degree in architecture. Before moving to Texas and joining three in 2016, David managed his own luxury residential firm for 16 years. Uniquely equipped with a keen eye for design and a strong understanding of construction materials and methods, David is able to visualize exactly how the construction materials will resonate in a space as he designs it. One thing he especially enjoys is integrating interiors with the natural world, or rather, bringing the outdoors in and the indoors outside. To date, David’s favorite project he has designed at three is the Caprock Members Clubhouse at Horseshoe Bay. On this project, David enjoyed the design freedom the client gave him to develop a concept that emulated the landscape, all the while creating unique technical construction details.
A people person, David also enjoys the marketing side of business and can be found each year attending the top hospitality conferences in the U.S. If you find yourself at one, he’d love to connect with you. To clear his mind and relax, David likes slipping away to his family lake house in South Carolina, mountain biking and exploring the outdoors in all seasons.

Rob Lara | AIA, NCARB
Principal / Senior Designer
Rob’s tenure with three began in 2002—four years after his graduation from Texas Tech University with a master’s degree in architecture. Establishing himself as a leader through his hard work, creative designs and attention to detail, Rob advanced his career within the firm and today, he serves as a Principal and Senior Design. He enjoys the collaborative design process at three: how it begins by involving all the key players and ends up reflecting a unique, unified vision. What’s most rewarding for Rob is the challenge of first listening to the client’s needs and wants, and then finding the right, tailored design solutions that bring the client’s vision to life. To that end, he says he doesn’t have a favorite project, but likes all the projects he’s worked on equally. His resume includes boutique resorts on Mexico’s Mayakoba coastline, luxury urban hotels and senior living communities.
If he wasn’t an architect, Rob says he would be a dare devil like Evil Knievel, his childhood superhero. In his down time, he enjoys relaxing with his wife and daughter, tending the chickens, and cycling around Dallas.

Christine Cook | NCARB
PRINCIPAL / Project Manager
Christine earned her master’s degree in architecture from Texas A&M University (proud Aggie!) and is on her second tour of duty at three. She first joined the firm for 11 years in 1998, before pursuing a different avenue in architecture for a few years, then returned to three in 2012 becoming a Senior Associate and Project Manager. In 2020, Christine was promoted to a Principal of the firm. She is passionate about mentoring the next generation of architects and spearheads the firm’s internal education committee: 3.edu. She also partners with Texas A&M and serves as a valuable resource to students studying senior living design. As a Project Manager, Christine is known for her attention to detail, organization and wealth of knowledge about state licensure, FHA (Fair Housing Act) and International Building codes. She’s driven by the desire to create unique, interesting experiences and spaces for the users that reflect their interests and values.
Christine can be found most weekends rink side at a hockey game, as both her children play competitive hockey, and she credits her passion for community involvement to her days as a Girl Scout leader. But mostly she loves getting out of Dallas and traveling with her family. Topping her current bucket list of places to visit is Cinque Terre, Italy.
