John Carr, AIC-PA
Principal Conservator

John spent 15 years in the field of architectural conservation prior to founding Materials Conservation in 2006. With a breadth of knowledge and nearly three decades of experience, John’s primary responsibility is the management of the firm and overseeing MC’s spectrum of projects. Clients often rely on his creativity to help develop strategies for funding projects. Co-workers rely on his expertise for inspiration and advice when they launch a conservation project.

John holds a MS and an Advanced Certificate in Architectural Conservation from the University of Pennsylvania, School of Design. He completed stone conservation coursework in Rome, Italy, holds a Professional Associate title with the American Institute for Conservation of Historic and Artistic Works, and belongs to the Association for Preservation Technology. John has been an active member on the board of the Preservation Alliance for Greater Philadelphia and the Dean’s Council at the University of Pennsylvania. Ever loyal to his Canadian roots, John is also a member of the Canadian Association of Heritage Professionals.

Green even before it was more than a color, John’s vision for adaptive reuse of buildings has already transformed the streetscape in the gritty section of Philadelphia that houses MC’s offices and studios. He’s aiming his sights on a new part of town: reimagining a factory warehouse into Materials Conservation's new headquarters.
