OSLER DENTAL PROFESSIONALS - Key Persons


Dr. Christopher J. Constantine

Job Titles:
  • Dentist
Dr. Christopher J. Constantine was born and raised in Towson, MD, and he loves providing exceptional dental services to his fellow community members. His interest in dentistry began at a young age. As a child, he required a lot of dental treatment but had a wonderful dentist, an experience that encouraged his interest in the biological and medical world. In his youth, he also had a strong affinity for art and worked on a portfolio of art pieces throughout high school, hoping to pursue art and design in college. The week before starting his college journey, he had a realization: dentistry was the perfect synthesis of his medical interest and artistic abilities. After changing his major, Dr. Constantine never looked back. He earned a Bachelor of Science from James Madison University before graduating from dental school at the University of Maryland. He also completed a one-year General Practice Residency at Christian Care Hospital. He holds a genuine passion for dentistry and likes the fact that he can bring his artistic side into dental appointments to improve his patients' smiles, creatively solving their dental problems. His favorite parts of his job include restoring form and function to his patients' teeth and seeing the changes his dental work makes in their lives. Dr. Constantine also appreciates the rapid pace of technology innovations in dentistry and loves incorporating new technologies into his practice to improve treatment outcomes and the patient experience. When he's not helping patients at Osler Dental Professionals, he loves spending time with his wonderful wife Heather, their children Charlotte and Max, and the family's Beagle mix named Daisy. He also still creates art outside the dental office, finding the most enjoyment in drawing and sculpting.
