Firm Info
Dennis Raffensperger founded dRA in 2013 after serving as University Architect at Montana State University for five years. Over 30 years of professional architectural experience provides an exceptionally strong foundation for a firm dedicated to providing design services across a broad range of program and building types founded on a commitment to excellence in design, construction, and client service.
Dennis first practiced architecture in Chicago after completing a master’s degree in architecture at Columbia University. After seven years working for several highly regarded firms Dennis opened a practice, Rugo/Raffensperger Architects, that was responsible for a wide range of work over the next nine years. Rugo/Raff created a very strong resume of work in the retail, commercial, corporate office and residential arenas.
In 1995 Dennis relocated to New Jersey and established Mendham Design Architects. Over the next thirteen years Mendham Design grew to become a regionally prominent firm in the field of custom residential work. Mendham Design served all segments of the residential market, historic preservation, remodeling, and new construction.
In 2008 Dennis sold Mendham Design, having made the decision to move to Bozeman, Montana, and accepted a position as University Architect at Montana State University. From 2008 to 2013 Dennis managed the design and construction group at MSU, overseeing the design and construction of a number of significant projects that have changed the face of the campus and raised the bar with respect to the importance of good design for campus buildings.
Dennis now brings the expertise gained from his previous firms and the university to dRA and is well positioned to provide his architectural experience to clients in Bozeman and the surrounding communities.
