Below is an excerpt from Portman Architects’ website.

Son of famed Atlanta architect John Calvin Portman Jr. and Jan Portman, John C. “Jack” Portman III MArch ’73 was born November 3, 1948 in Atlanta, Georgia. Jack graduated from The Lovett School in Atlanta, then earned a Bachelor of Architecture from the Georgia Institute of Technology and a Master of Architecture from Harvard University’s Graduate School of Design. He began practicing architecture in 1973 at John Portman & Associates, rising from an Apprentice Architect to become Chairman of the firm, now known as Portman Architects.

Jack took over leadership of Portman Architects following the death of his father, John C. Portman Jr., in 2017. While exceedingly successful as a real estate developer, Jack was passionate about being an architect, particularly the creation of meaningful architecture with a focus on culturally sensitive design. He once said, “The challenge of the architect is to do something that seems to belong where it is situated.” Throughout his nearly 50-year career with the Portman Companies, Jack pioneered their international expansion, helping to transform the enterprises into the globe-spanning real estate design and development firms that they are today.
