Our Practice Philosophy

The primary focus of everything we do at Mosinee Smiles will always be providing specialized patient care. Our staff will never put any pressure on you to have a service or operation, and we always endeavour to ensure that patients are fully informed of all of their treatment options. We’ll do everything we can to protect your natural teeth wherever possible. We will treat you like a part of our family from the moment you walk into our office, and we would never provide care or advise that we wouldn’t provide to our own families. In every situation, we make an effort to inform patients about everything we do, from procedures to billing, because we believe that dental decisions should be honest and unambiguous. Our professional staff and I believe that dentistry should be pain-free.

Meet Our Dentists

George Knoedler, DDS

Dr. George Knoedler has been a fixture of Mosinee dentistry for over three decades. His dedication to his patients and the larger community has made a significant impact over the years and has made him one of the most respected professionals in our area.

He is a wonderful ambassador for both personalized dental care and small-town business.

Dr. Knoedler was born and raised in Mosinee and has called it home for the majority of his life. He attended UW-Marathon County for his undergraduate studies and graduated with his DDS from Marquette University Dental School. He served in the United States Navy and was deployed oversees for a number of years. The two biggest influences on his decision to enter the dental profession were his ambition to own his own business and his desire for small-town living. Dr. George has always been committed to continuing education, both for himself and the professionals he has hired over the years. This ongoing study of dental procedures and technologies is a big part of our office’s success. What Dr. George enjoys most about working at Mosinee Smiles is the opportunity to serve multiple generations of patient families, providing them with the greatest personalized care possible.

Outside of the office, Dr. Knoedler enjoys coaching basketball, writing, participating in various Mosinee activities, and spending time with friends and family. He follows and supports local Mosinee athletics and extracurriculars, as well as Wisconsin sports. A little known interesting fact: Dr. George has attended Clown Camp and performed in a clown troupe. In general, he loves helping other people and putting smiles on their faces.

Eric Umhoefer, DDS

Dr. Eric Umhoefer is originally from Neenah, Wisconsin. After graduating from Neenah High School, he went on to graduate Magna Cum Laude from the University of Wisconsin-Madison with a Bachelor of Science in Biology and a Certificate of Excellence in Stem Cell Sciences. He then followed this by earning his DDS from Marquette University School of Dentistry. Dr. Eric always knew he wanted to do something to help people in the healthcare field, as his mother was a nurse and his father was an emergency room doctor. After shadowing his dad in the hospital, Dr. Eric appreciated the opportunity for providers to fix acute problems to help patients feel better, but it seemed to lack the opportunity to get to know and form long-lasting relationships with patients. He enjoys that dentistry allows him to form that close, long-term relationship he hoped for, as well as the chance to utilize his hands and to problem solve. Dr. Eric believes in building mutual trust, respect, communication, and understanding to properly treat patients with attentive and compassionate care.

Dr. Umhoefer has had a positive impact on our Mosinee Smiles office through his patience and understanding, which allows him to effectively form relationships and trust with patients. He’s aware that dentist visits can be a stressful time for some, but his calm demeanor allows patients to feel comfortable and at ease in the chair. Dr. Eric is hardworking and always open to learning new information and techniques. When it comes to working and serving our patient family at Mosinee Smiles, he loves serving beside and learning from our talented, experienced practitioner, Dr. George, and our intelligent, hard-working staff. He’s very excited to continue his dental journey with our Mosinee Smiles team. Dr. Eric has immediately taken to his new Central Wisconsin home: he enjoys being in this community and experiencing the numerous activities our area has to offer, whether it’s skiing Granite Peak, kayaking the Wisconsin River, golfing at a local course, or exploring the local trails.

Some of Dr. Umhoefer’s other favorite activities out of the office include biking, fishing, and playing volleyball. He grew up enjoying most of his summers with his family at their cottage on Long Lake in Waushara County, and that love of the outdoors continues to this day. He’s also an avid sports fan and diligently follows the Green Bay Packers, Milwaukee Bucks, Milwaukee Brewers, and Wisconsin Badgers.

Meet Our Staff

Bernadette – Dental Hygienist

Bernadette, one of our talented dental hygienists, grew up in a tradition of dental care. Being the daughter of our dentist, Dr. Knoedler, gave her a sense of what working in this field is all about, and she has enjoyed carrying on this family legacy in Mosinee. Bernadette was actually born in Rota, Spain, as her father was stationed at that U.S. naval base during the time. After moving back to Mosinee, she graduated from Mosinee High School and went on to earn her Bachelor of Science in Dental Hygiene from the University of Minnesota. Bernadette has served our patients since 2005, and her flexibility of schedule has allowed her to work different times each week depending on the office needs. Some of the things she enjoys best about being a hygienist are helping patients find confidence in their oral health and become proud of how they feel when they smile. She particularly enjoys working in and serving our Mosinee community because patients become friends in a smaller community. Outside of work, Bernadette enjoys reading, spending time on the lake, and being a basketball coach.

Robyn – Dental Hygienist

Robyn was born in Dodgeville, Wisconsin. After graduating from high school and later earning her Dental Assisting certification from Southwest Wisconsin Technical College, she moved to central Wisconsin in 2012. What drew Robyn to the dental field was her experience as a child having poor oral health: she wanted to become part of the dental profession to help educate others—especially children—on the importance of oral health. She believes if people are educated on the connection between oral health and overall health, as well as the proper tools, techniques, and products of dental hygiene, they will find a much more positive and healthy lifestyle. Robyn brings a welcoming attitude and great communication skills, along with over five years of dental experience in multiple roles. What she likes most about working at Mosinee Smiles is the friendly atmosphere and being part of a great office that offers outstanding care to our area. Outside of work and school, Robyn loves spending time with her husband and two young boys, along with their three dogs. Two of her favorite activities are camping and cheering on the Wisconsin Badgers. She also enjoys photography and spending time with family outdoors.

Savannah – Dental & Administrative Assistant

Savannah is originally from Stratford, Wisconsin. She was drawn to the dental field after being an orthodontic patient. She loved experiencing the transformation of her smile, and she now loves to watch that same kind of transformation in our patients. When it comes to her philosophy of care, she strives to improve the quality of life and health in patients, to educate them on dental health, and to establish long-term relationships built on trust. Her versatility and preparedness for whatever situations arise are parts of what make Savannah such a great asset to our office. She’s excited to be serving the Mosinee community, and she looks forward to our continued growth. Apart from her work, Savannah enjoys hunting, fishing, and running.
