Meet the Doctor

Mary Frances Jahnke, D.D.S.


A proud native of Lake Country, Mary Frances is thrilled to bring her family dental practice to her hometown of Oconomowoc. She received her Bachelor of Science degree at Marquette University and her Doctorate of Dental Surgery at the University of Minnesota’s School of Dentistry in Minneapolis.



She completed a two-year residency program at the Clement J. Zablocki VA Medical Center in Milwaukee, where she served veterans with comprehensive dental care.  There she orchestrated complex treatment plans encompassing all facets of dentistry, notably: the restoration of dental implants, crowns, bridges, root canals, removal of teeth, and the fabrication of removable prostheses such as dentures or partials.


When she’s not at the helm of Jahnke Dental, Mary Frances is always on the look out for opportunities to continue her education in dentistry, attending courses both locally and nationwide.


Dentistry runs in the Jahnke family and Mary Frances is proud to continue the legacy. Her grandfather Earl Jahnke was a general dentist outside of Madison, and her late father Peter Jahnke was a periodontist (gum specialist) here in Oconomowoc. Mary Frances learned from the best, and so gained her passion for providing patients with a comfortable and painless dental experience.


Mary Frances is a member of the American Dental Association, Wisconsin Dental Association, Academy of General Dentistry, and the Frank Spear Study Club.


She is a lover of food, film and travel, and is always interested in learning new things!
