Becoming a part-owner of the Jones and Kell, Inc. architectural firm in 1993, Muñoz, not an architect, entered the field of architecture and design. The firm was renamed Kell Muñoz Wigodsky to reflect the three partners. In 2000, the firm was renamed Kell Muñoz Architects, Inc. after Dan Wigodsky left to start a private practice. In 2008, John Kell, Jr. retired and the firm became Muñoz and Company in 2013. Muñoz & Co has a widely diverse portfolio of projects including governmental, institutional, higher education, public education and corporate work. Their designers have been recognized with more than 143 juried design awards, and their work has been featured in The New York Times, Wall Street Journal and Architectural Digest, among others.
