We are Grassi & Grassi, PC — the oldest, continuously-operating Endodontic Practice in Monroe County and the regional, five-county area. Founded by brothers Gerard T. Grassi and David Grassi, the practice opened in 1973 in the Temple Building in the heart of downtown Rochester. Today, we have offices in Brighton and Greece, operated by partners Dr. John E. DeAngelo and Dr. Michael D. Grassi.

What makes Grassi & Grassi unique is our dedication to our patients. Our staff members are employees of long standing with an average tenure of over 20 years! We pride ourselves on our knowledge of our field and our attention to the needs of each person we serve. When you enter either of our Grassi & Grassi offices, you become our #1 priority.

At Grassi & Grassi, we have many patients who have returned to us for their endodontic needs. We believe patients return because they recognize our commitment to providing them with services of the highest quality. We give each person the individual attention they deserve. We accept referrals from all the dental practices in the region — from individual private practices to large group practices alike.

Emergency treatment is available when needed at either of our two convenient locations. Our offices are open from 7:30 a.m. to 4:00 p.m., Monday through Friday. Emergency treatment is available on weekends and holidays when medically indicated.
