Dr. Lisa Lipari

Professional, caring, thorough. Coordinated care with an anesthesiologist for my 10-year-old who required sedation and made him feel very comfortable. Worked quickly and efficiently to minimize the duration of the procedure. Did not do anything that wasn't needed. Highly recommend.

Kerry H.

Absolutely wonderful! The best dentist I have ever been to. As soon as I called the receptionist was helpful and welcoming. When I arrived everyone worked to help make me feel better. I needed an emergency x-ray and a root canal and it was done right away! As the hygienist promised I didn't even feel the dentist numb the area. Dr. Feigelson performed a pain free root canal.

Abbey M.

Dr. Feigelson and his staff are wonderful! I had a fairly lengthy procedure over multiple visits and he was very gentle and clearly explained everything to me step-by-step. The office is very nice, clean and comfortable and I highly recommend Dr. Feigelson to anyone!

John M.

Forty years of dental fear disappeared almost instantly when I visited Dr. Feigelson. I would unconditionally recommend him to anyone who fears or has had negative experiences with dental care.
