Our philosophy is the same as it was in 1975.

Communication and a sell through approach have helped us build strong, long-term relationships with our dealers & vendors.



Richard Dean Associates was established in 1975 by partners Richard Bazirgan and Dean Goodwin as a manufacturers' representative firm based in New England. Dean left the business in 1984 and Dick remains the sole principal and has been perfecting his marketing skills in the audio industry for over thirty years. His blend of personality, professionalism and experience is a rarity in our industry and his outstanding relationships with manufacturers and retail chain stores has been the key element to achieving results based upon long-term sell through. Dick's commitment to assure the best customer service possible keeps the RDA team at the forefront of the industry.


Nothing says success like results!
