Patient Reviews

“Very professional, and treats their patients with care. They also provide great feedback and make referrals to other places that can provide additional procedures.”

-Ramon V.


“I just had a temporary crown implanted and I felt only a punch from the injection. The procedure was a piece of cake. Dr. Costa and Marcy performed this procedure efficiently and painlessly. I highly recommend them for your dental care. I’ve been coming to this practice for over 25 years.”

-Annette B.


“I had avoided dental appointments for years due to anxiety. I’m so glad I finally went to see Dr. Costa. He was very understanding about my anxiety issues, and Michelle and Marcey made me feel so comfortable during my appointments. Cynthia in the office is wonderful and so helpful. I’m so happy to be a part of this practice.”

-Jill M.
