Diamond Windows & Doors Mfg. Inc.

Diamond Windows & Doors was founded in 1992 by Tony Tseng. Tony followed in his father’s footsteps into the building and construction industry as a contractor and property developer in Taiwan and later New York City when he arrived to America. After years of experience in the big apple, Tony decided to take his knowledge to Boston and start Diamond Windows & Doors. Using his understanding of the industry, Tony has made it his goal to meet and exceed the requirements of architects, developers, and home-owners. With this knowledge and the contacts that he has made over the years, Tony soon had a successful window manufacturing business operating out of a 20,000 sq-ft facility in the Brighton-Allston neighborhood.
