My experience getting an implant was amazing, The care, speed and innovation was only matched by seeing the joy in which Dr. Leitner and his team do their work. Best dentist I have ever had, and the cost was literally half of the 2 other estimates I was given by other offices.


Meet Your Dental Team in Grand Haven, MI

John Leitner DDS


Grand Haven born and raised, followed by a roundabout way back. Time at MSU, a bicycle trip that ended in Montana with me working in a dental lab and a D.D.S. from University of Michigan in 1982, practicing in Pennsylvania and then coming back home to take over my father’s dental practice in 1990.

My priority is always patient relationships. I have an equal commitment to learning the latest techniques and investing in helpful technology, at no added cost to patient care. My office was the first to embrace enhanced microscopic dentistry, one of the first to offer complete digital records, and laser treatments. The world is constantly changing and advancing, and I believe continuing education combined with flexibility is important in offering excellent care for my patients.  When I’m not caring for patients you will find me swimming, biking and enjoying time with my family.

Colin Pellegrom DDS, MHS

Associate DDS

Aside from higher education, I have lived and worked in Grand Haven my entire life. I am a Michigan State graduate (BS – Biochemistry and Biotechnology), a Grand Valley State graduate (MHS – Biomedical Science), and an Indiana University graduate (DDS – Doctor of Dental Surgery). I returned home from Indianapolis after dental school to reunite with family, the water, and the community that I love so much.

Evidence-based, patient-centered care is what I provide, but patient relationships are what I build. Everyone seeks a place where they are treated with respect and where you feel at home, and that is what this office provides. I am so proud of our diverse staff that serve our patients from a hometown perspective as well as a global perspective! Talk to me about water skiing or alpine skiing, travel plans or sharing travel pictures, and being outside in general.
