Meet the Dentists

Sean A. Cooper, DDS

Being a parent myself, I know how important it is to choose the right dentist to trust with your child’s oral health. It is my goal to provide the best care possible in an environment that is comfortable and non-threatening. I am always pleased when a child leaves our office knowing that there is nothing to fear when going to the dentist.

In accordance with my Eagle Scout pledge to “give back to Scouting all it has given to me” I have been a Cub Scout leader since my oldest son entered the Pack. To relax, I enjoy such activities as camping, flying small aircraft, watching movies while completing puzzles, and of course, sailing!
