What Our Patients Say

"Very Impressed"

"As the widow of a Dentist, I was apprehensive about seeing Dr. O'Shea as a new patient. I was very impressed with his professional manner and kind demeanor. He is an excellent dentist, very knowledgeable and put me at ease immediately. 
Dr. O'Shea is gentle and compassionate and I would highly recommend him."

– Janice S –


I am very happy that I found this dentist. I had pain in my back tooth and went to 2 other dentists who wanted to charge me large amounts of money to help me keep my tooth. Dr. O'Shea was considerate and gave me alternative options that helped take me out of pain and stay stable until I was ready for the final crown. I'm glad 
he moved into the neighborhood. Highly recommended.


"I had major work done with Dr.O'Shea and he explained everything to me with what to except and what not to expect. He also answers all your questions and makes you feel comfortable. I don't like dentists but I wouldn't change Dr O'Shea for the world. I highly recommend him to anyone that has a fear of dentists and is looking for a great dentist."
