  • Rebekah Sheppard

    Knowing that she wanted to be a dentist from a young age, Dr. Sheppard attained her Bachelor of Science degree from Eastern Michigan University while working as a dental assistant.  In 2011, Dr. Sheppard graduated from the University of Michigan, earning her Doctor of Dental Science degree.  Since then, Dr. Sheppard has spent years in both private practice and public health, and has also worked in administrative dentistry as a Quality Control Director for dentists.  Dr. Sheppard is a member of both the American and Michigan Dental Assocations.  

    While Dr. Sheppard is orginally from Clinton, the Sheppard family has recently moved to Gaylord.  Dr. Sheppard and her husband have two wonderful daughters, Ryann and Emma.  The girls are sweet, energetic, and keep their parents on their toes.  The Sheppards enjoy the outdoors (boating, golfing, and snowmobiling), and are looking forward to all that Gaylord has to offer.

Now that his children are grown, Dr. Zelazny has chosen to relocate and join our growing practice here in beautiful northern Michigan.

    Dr. Zelazny loves to help people achieve the smile they desire. With his many years of experience, cosmetic dentistry has become his passion. So that he may provide all aspects of perfecting smiles, Dr. Zelazny is also a certified Invisalign provider. Over the years, he has donated his services to the underprivileged in Honduras, Guatemala, Mexico, Bolivia, Viet Nam, Jerusalem, and El Salvador. In his spare time, you may find Dr. Zelazny playing his guitar, cooking, fishing, or photographing the great outdoors.
