Meet the Team

Dr. David McNeal, D.M.D.

Dr. McNeal has been practicing dentistry in his hometown of Harrisburg, PA for more than 20 years! After receiving his Bachelor of Science in Biology from the University of Scranton, and attending Temple University, School of Dentistry, he completed a general dentistry residency at York Hospital. Dr. McNeal ultimately returned to Harrisburg, where he was born and raised, to practice dentistry. Since the beginning, his goal has been to provide his patients with the highest quality of dentistry available, in a relaxing environment. His friendly personality helps make patients feel at ease and his dedication to continued education in the latest dental procedures helps ensure that the practice is providing the best care possible. 

When Dr. McNeal isn’t seeing patients, you may find him mountain biking, spending time at his cabin in Potter County, enjoying a football game (Go, Penn State!), or with his family and supporting his daughter at an Irish dance recital.

Dr. Erin Vieira, D.D.S.

Dr. Vieira joined the Mechanicsburg Dental Associates team in April of 2021, after serving practices in Ohio and PA. She received her Bachelor of Science from Bowling Green State University in Ohio, with a major in Biology and a minor in Chemistry. She went on to receive her D.D.S. from The Ohio State University and completed her residency with St. Joseph Mercy Oakland. During her residency she was able to provide dental care to an underserved population, while gaining experience in a comprehensive dental care environment. After practicing dentistry for several years, Dr. Vieira made her way to our part of PA where she joined our practice!

If you have the opportunity to meet Dr. Vieira, you may end up chatting about favorite hobbies, like cooking, running, cycling, and yoga, or about her family, including her husband and two daughters.
