Dr. LeitnerJohn O. Leitner, DDS

Dr. Leitner was born and raised here in Grand Haven, MI. After finishing high school he attended MSU for two years. The opportunity to travel was too great for him, so he headed out to Montana via bicycle. While living in Montana for almost four years, he found a job working as a dental assistant for a short time, and then as a dental lab technician. It was during this time that he found he had a strong desire to go into dentistry itself. He received an excellent practical lab education, which is still useful on a daily basis today. He received his D.D.S. from University of Michigan in 1982. Following his degree he worked in several different settings to gather knowledge and skills. He owned a practice in Pennsylvania for five years before coming back home to take over his father’s practice in Grand Haven, MI. With all these different learning situations, he feels he has something unique and positive to offer the community.

In today’s world Dr. Leitner feels it is important to keep a personable office atmosphere, but offer services based on current techniques and technical advancements. His office was the first to embrace surgical microscopes and TekScan occlusal analysis in Western Michigan, and one of the first to offer complete digital records, and Periolase laser treatments. The world is constantly changing and advancing, and he believes continuing education combined with flexibility is important in offering excellent care for his patients.

Dr. Leitner has lived in Grand Haven again since 1990. His wife and two children enjoy keeping him busy with skiing, boating and "kid-stuff!"

Darbee McCracken CDA, RDA Clinical Team LeaderDarbee, CDA, RDA, Clinical Team Leader

Darbee has been practicing in the dental field for 27 years and loving it!  Darbee has been with Dr. Leitner since November of 2008.  She was fortunate enough to experience and learn from a couple of dentists out in New Mexico before returning to Michigan to start a family. She received her license for RDA (Registered Dental Assisting) through Ferris State and Washtenaw Community college in Ann Arbor.  The past few years an opportunity through Dr. Leitner’s practice developed, and under the direction of Dr. Leitner, an Interactive Healthy and Unhealthy Mouth Program was designed. With this unique presentation we were invited within the local school district and libraries. This is where my professional passion for healthy thinking can “bloom and thrive”. My professional mission statement is simple- “Patient kindness and education”.  I’m a mother of two beautiful daughters and am happy to be raising them here in my home town. My interests are becoming a consciously aware individual. A perfect day for me would be time with my family on the beach.
