About Us

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.

It’s About More Than Just Teeth.

Patient respect and care come first, always.

Beyond teeth and oral health, there’s a lot more to a dental relationship. We get that. We and our families have to go to the dentist, too. We understand that the “other stuff” matters as much as what happens in the chair – things like scheduling, insurance, cost planning, accessibility, convenience and most importantly, respect and kindness! We love to create happy patient experiences.

We’ve got you covered in the teeth department, too, btw. Our office has the most advanced technology available and is 1 of only 5 in Michigan to use a high powered microscope to provide 20 times the visibility and precision than others.

Meet John Leitner, DDS


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.

Meet Colin Pellegrom, DDS, MHS


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.

Frequently Asked Questions

I had a bad experience at another office and now I’m afraid of the dentist.

If you’re afraid of needs, it’s important to stay calm and know that Dr. Leitner and our Grand Haven team are here to help. We use the best, most effective numbing agents available to relieve any pain or discomfort you may be feeling. Before your procedure, we’ll apply a numbing jelly on your tissue that’s so strong your tissue will get that “asleep” tingle. Most patients don’t even feel the injection, allowing you to relax throughout the procedure.
