Graham Billingsley has significant experience covering more than 35 years of practice. Educated in planning, landscape architecture, and architecture, and having practiced in all three fields, he is able to develop solutions that are practical and innovative, designed to solve the problem specifically for the community. For 23 years, Graham was in the public sector, first as Chief Planner for Urban Design with the City of Dallas, Texas.
