When she’s away from the office, Dr. Stiles enjoys volunteering within the community, as well as reading and traveling. Drs. Dennis and Marie Stiles have three children: Elizabeth, Andrew, and JP and grandsons: Tommy and George. 

“I really value the relationships I’ve formed with my patients, and I’ve learned an awful lot from them. We talk about things like parenting, colleges, travel tips, and good books to read. Yes, I really like helping people with their mouths, but what I love is that my patients let me into their lives just a little bit. I learn something different from everyone.”
