Julius S. "Jack" Baum is the principal of Tree House Design Ltd., his namesake firm, offering in-depth design services to the Restaurant and Hospitality industry concentrating on Interior Design, Lighting Design, Space Planning, and Graphic Design.

Born in Memphis, Tennessee in 1956 and raised in Mississippi and Tennessee, Jack studied architecture at the University of Tennessee in the late 1970's where he received his Bachelor of Architecture degree. He is currently a licensed architect in the state of New York and is NCARB Certified.

Upon arriving in New York City in 1979, he started working with the renowned Interior Designer, Angelo Donghia, as a member of his contract design team. It was here that he was introduced to the world of Hospitality Design working directly with Angelo Donghia on the design of Restaurants, Hotels and public spaces in Private Clubs and Apartment Buildings. Jack was also able to assist Angelo Donghia on the design of several high end residences for his celebrity clients.

In 1983, Jack began to concentrate more intently on food related design by joining Tihany Design, world famous for award-winning restaurant designs. It was here, working directly with Adam Tihany that he learned to take heed to the overall design and appearance of hospitality spaces along with the importance of lighting design that is so critical in providing flexibility and ambiance to the Dining or Retail experience.

After four years with Tihany Design, Jack became affiliated with the Office of Philip George, famous for his designs of many successful large scale and long running restaurants and his collaborations with well known restaurateur Joe Baum. Here, he learned the importance of a well thought out floor plan and the separation and integration of public spaces and service areas.

Since 1990, Jack has led Tree House Design Ltd. to become a highly recognized Restaurant Design firm with a uniquely American Design sensibility working on projects of all sizes from large multi-million dollar restaurants in New York and Las Vegas, to smaller projects throughout the United States where design and function are considered as important a criteria as food quality and service. One of the hallmarks of Jack's abilities is the flexibility to listen and design according to the goals and needs of his clients and not to satisfy his own personal style, resulting in over several hundred restaurants during the past two decades which have successfully responded to the demands of the marketplace.
