Joshua M. Roper, PE, LEED® AP | Principal Consultant

Since joining Charles M. Salter Associates in 2001, Josh has specialized in environmental and architectural acoustics and mechanical system design. Josh enjoys working on a variety of projects, including schools, libraries, hospitals, single and multi-family residences, and commercial and industrial spaces. His study of helicopter noise for Good Samaritan Hospital helped to permit a new helipad to transport patients in need of medical services. Josh worked on the acoustical design of the Hillview, Almaden, and Rosegarden library branches in San Jose, California.

Josh's interest in sustainable design led to accreditation with the U.S. Green Building Council, which inspired him to install a photovoltaic system at his residence. He is currently involved on multiple LEED® projects and looks forward to expanding his experience.
