Thomas E. Sprinkle, AIA



Mr. Sprinkle is a founding Partner of Dunnigan Sprinkle. He has more than 30 years of professional experience as an Architect in the San Francisco Bay Area and has managed and designed a wide variety of residential, mixed use and hospitality projects that range in scale, complexity and location. He has worked throughout the United States and abroad through all phases of architectural design, from concept development to design development, to preparation of construction documents, and construction support.  Mr. Sprinkle has developed a management style that is effective and collaborative, and well appreciated by clients, regulatory agencies, consultants and in-house staff. ​

Tom started his college career majoring in Engineering, with a heavy emphasis on math and science.  However, he soon found himself taking art classes; sculpture, life drawing, fine arts; and painting soon became a major focus of his curriculum. Drawn to the creativity he experienced in the art program, but still stimulated by math and science, he embarked upon a career in architecture. What excites Tom about design is the process itself. The dynamics of the team approach to design, being around creative people and leading the efforts to blend diverse viewpoints and backgrounds into unique and cohesive ideas is the focus of his day. ​

Tom graduated magna cum laude from Arizona State University, and lives in San Francisco with his wife and three children. Tom is engaged in the local community through professional and personal ties built over his 30 years as a resident of San Francisco. Gardening, cooking and riding his motorcycle round out his free time.​
