Dr. Chad Goeke

Dr. Chad Goeke was born and raised in a small farm town of 700 people called Davis in the Northwestern area of Illinois. He received his undergraduate degree in Biology at Carthage College in Kenosha, WI. While there he met his wife, Shannon, who is a native of Fond du Lac. After Carthage, he received his Doctor of Dental Medicine from University of Illinois-Chicago College of Dentistry. He and Shannon then moved back to Fond du Lac to start and raise a family. He loves the small town feel of Fond du Lac and is excited to become part of it. He enjoys helping the members of our community in any way he can and truly loves what he does. He has taken courses in Invisalign, implants, and same-day crowns. Outside of dentistry his interests include fishing, snowmobiling, the occasional video game, and of course the Chicago Bears!


Dr. William Mauthe

Dr. Mauthe has now retired as of January 1st, 2018. He practiced here in Fond du Lac for over 40+ years and helped thousands of patients in that time. He saw dentistry undergo a plethora of changes and is proud to know that this office will keep up with the changes in this new millennium. He made a commitment to continually update our techniques and services with continuing education and we are happy to carry on that legacy. We are very lucky to have had him as a guiding hand in the way we practice dentistry here at this office and he will be missed. With his newly found extra time, he will be able to spend it with his wife, kids, and grandkids.
