About Dental Associates
Dental Associates, founded by Dr. Sumner Hirshberg in 1947, is the oldest group practice not only in Quincy but all of Massachusetts. Dr. Hirshberg set out to provide the practice’s patients with quality, state-of-the-art dental services. We continue to follow his vision.
Currently, we are owned and operated by Dr. Lewis Hootnick. He and his dedicated team offer comprehensive dental services for the whole family, including implant placement and restoration.
