Bob Thomas is a founding partner of Campbell Thomas  & Co. Architects, founded in 1976 and a firm noted for historic preservation, energy conscious design, community development, greenways, accessible design and appropriate technology.  As Partner in Charge, of numerous architectural, planning, greenway, solar, bicycle and public transportation projects he has worked with such agencies as the Fairmount Park Commission (Fairmount Water Works Master Plan, Chamounix Mansion Carriage House, Fairmount Park Bikeway and Rail Trail), the Pennsylvania Department of Transportation (Radnor Multi-Purpose Trail), and the Montgomery County Planning Commission (Philadelphia - Valley Forge Bikeway, all four phases).  All these projects have required significant planning and programming skills to meet numerous planning goals, often in conflict.

In addition to his architectural skills, Mr. Thomas previously worked as a planner for SEPTA, and has worked on the transportation-planning project of the Philadelphia Zoo Transportation Center that will serve Fairmount Park as well.  His knowledge and use of public transportation is invaluable in planning sites to be accessible by all sectors of the population.

He is an expert, as well, in historic preservation and handicapped accessibility. He has applied this knowledge successfully towards projects such as the restoration of the magnificent Brentwood Apartments facing Fairmount Park, the Metropolitan Baptist Church Accessibility Improvements, which included the insertion of an elevator into an historic 19th century church, and Lower Merion's historic Affordable Housing for the Elderly in Bala Cynwyd.

In recognition of his achievements and advocacy for accessibility, he was appointed to, and continues to serve the Chair of the City of Philadelphia’s Accessibility Advisory Board. In this capacity he has reviewed over 500 projects, assisting in the development of innovative solutions to meet the spirit of the code and law; thus resulting in the 1997 President’s Access Award.
