Cottman Glass & Mirror is a glass specialty business located on Davisville Road in Willow Grove. Cottman has been in business in the greater Philadelphia for more than 25 years and has only recently set up shop here due to a fire at the company's previous location. A large majority of the work is done by owner John D'Annunzio, but a small staff is available for larger projects. Cottman does a variety of jobs with glass and mirrors, working in conjunction with contractors and as its own independent entity. The company primarily works in the residential and business sector, most specifically providing frameless glass shower pieces for home remodeling and renovation.
