We love new patients

  • "I have been a patient of Dr. Bogin for over 20 years and think he is the best! He is easy to talk to, gently and very knowledgeable. He and Mary Ellen have saved my teeth inspite of caps, crowns and extractions. I would not consider going anywhere else. Parking is plentiful and the office very pleasant."
    Carol S.
  • "Great staff, very friendly. Dr. Boadway was very skilled, friendly, attentive, and invested in her work. The most attention I’ve ever received for oral procedures, she ensured that my filling was comfortable, and was very helpful. Highly recommend!"

I have been a patient of Dr. Boadway for many years now & she has always made my visits pleasant. She will never be condescending and will always reassure you everything will be fine. She's gentle, amusing and very knowledgeable in her field. I highly recommend Cold Spring Dental."
