Mark DeMaria, DMD, MS
Dr. Mark DeMaria completed his Bachelor Science degree in biology from Seton Hill University in 2007 and his Master of Science degree in 2012. He attended the Temple University Maurice H. Kornberg School of Dentistry, graduating in 2012. He then completed an internship at Seton Hill Center of Orthodontics, followed by his orthodontic and dentofacial orthopedics residency which he completed in 2015. During his residency, he also provided affordable dental services to the underserved at a clinic in Pittsburgh’s North Side.
Dr. DeMaria understands that a “perfect” smile is often the main goal of orthodontic treatment, but he also believes that the treatment experience needs to be as comfortable and convenient as possible. For this reason, he regularly completes continuing education courses to stay up to date with the newest techniques, technologies and trends in orthodontics. He has received advanced training in Invisalign® treatment for both teens and adults. Dr. DeMaria has practiced in the Greensburg area since 2020.
Dr. DeMaria is a member of the American Dental Association® (ADA), the American Association of Orthodontists® (AAO) and the Pennsylvania Dental Association (PDA). He has achieved Invisalign Gold+ provider status and in 2022 was named Reader’s Choice Best Orthodontist by the Latrobe Bulletin. As a dentist, his goal is twofold: First, to develop a reputation as a doctor who puts his patients needs and interests above all else, and second, to become the number one office patients choose when receiving braces or Invisalign treatment.
Dr. DeMaria grew up in the Greensburg area and has strong roots in western Pennsylvania. He is proud to practice in his local community. When not in the office, his hobbies include hiking, reading, bike riding, golfing, spending time with his friends and family, and trying to stay in shape.
