Tribute to Our Late Founder of the Practice

Our practice was founded in 2008 by Dr. Peter L. DeMizio utilizing the principles and skills developed during a 20 plus year career in the US Army Dental Corps and many years subsequently in private practice. Dr. DeMizio dedicated his entire life to health care and providing the absolute best treatment to his patients regardless of cost, time, or effort. The best treatment in his mind for any patient was always the most ethical and painless.

He reveled in the opportunity to practice with his son and wife and be able to treat patients just like his own family. While Dr. DeMizio is not physically present in the office, his ideals and legacy live on every day at DeMizio Dental center.
