Meet Dr. Mark Hagan

  • A Love for Helping Others

    Dentistry has the ability to positively change people’s lives; my satisfaction as a dentist comes from having healthy and happy patients, who are leading better lives because of the care I’ve provided.

    I chose to become a dentist after having extensive dental work done as a child and orthodontic treatment when I was in high school. The before and after photos blew me away. Seeing and experiencing, firsthand, the way dentistry transformed their face and smiles made me want to provide the same experience for others.

    I’ve been practicing in York, PA since January 1986. The practice was established in 1954 by Dr. Jay Weist and I was fortunate to have worked with and learned from him before his retirement. It’s an honor that many of his patients have stayed with our office, and I’m now caring for a third generation of patients, all of whom have placed their trust in me and our team to provide them with dental care that’s gentle, compassionate, and effective.

    Education and Continuing Education

    I graduated from William Penn Senior High School, received a Bachelor of Science in biology from the University of Pittsburgh, and was awarded my Doctorate of Dental Medicine from the University of Pittsburgh School of Dental Medicine.

    Continuing education is a passion of mine. I prefer to learn at meetings and conferences rather than through online courses. Hands-on education is important, because it gives me real-world experience that I can take back to my patients. Some of the topics I pursue are dental implants, crowns, bridges, and oral surgery, all of which I can use every day to benefit my patients.

    • Away from the Practice

    I was born and raised in York, and have chosen to remain in order to care for my family and friends. My wife Denise and I have a passion for dogs and a love of the outdoors. She owns a medical practice here in town, Kenna Plastic Surgery, and is an accomplished surgeon. If I’m not at work, you’ll most often find me fly fishing, cooking, gardening, or walking the dog. I also enjoy being with family and friends, and believe in living one day at a time.
