  • Dr.
    Thomas McKenny

    I really love being a dentist. It allows me to make people healthy and proud of their smiles. I believe dental treatments can be life-changing. Furthermore, dentistry allows me to do small detailed work. Teeth are amazingly small, but their impact can be felt over the entire body. I make sure that patients are given personalized treatment plans as well as the time and attention to become experts of their own oral care. With me, patients smile often and for life.

What Our Clients Say About Us

  • "I have had 2 appointments at Thomas F. McKenny General Dentist and both were of complete satisfaction. The staff were friendly and welcoming, which gave me a great first impression.

  • "I have always had a great experience with Dr. McKinney and his staff. They always treat me as if I'm the most important patient in the office. It's obvious that they love what they do. Dr. McKinney turned what was once a hopeless mouth into a smile that I'm always eager to show off! I wouldn't go to any other dentist! Thank you Dr. McKinney!"
    Oscar B
  • "I have been with Dr. McKenny and his stellar team for about six years, now. I was referred by another dentist and have not considered going anywhere else since my first visit, even during periods when I did not have dental insurance or when my specific plan would have served me better somewhere else. There's also a lot to be said for his leadership when the team that is taking care of my dental needs today from front desk to hygienist to dental assistants is the same team that took care of me when I first visited. It's "almost" fun going to my dentist. Dr.McKenny and his team get my highest rating."

  • "It was a wonderful experience. The exam was extremely through and the staff was very friendly. It took awhile to get through everything, but I didn't mind because of the quality of service."
