Our History

Dr. Timothy T. Ryan purchased this long-standing practice 24 years ago from Dr. Mike Weinzierl, who bought it from Dr. Rexford Stearns at least 30 years ago. We still treat many of Drs. Stearns and Weinzierl’s original patients. We were voted Best Dentist in Winnebago County by the People’s Choice Awards in Oshkosh for our outstanding dental practice.

Dr. Timothy Ryan

Timothy T. Ryan is originally from Milwaukee, WI where I attended Marquette Dental School Class of 1985. My wife SueAnn and I have raised our children Patrick and Meghan in Oshkosh for the last 27 years. I am a member of the ADA, WDA and Winnebago County Dental Society. I am a board member of the Salvation Army in Oshkosh as well as a volunteer dentist for the Tri-County dental clinic. In addition, I have been on numerous mission trips that include Bolivia and the Dominican Republic.

I am committed to offering the finest in dental care to my patients in a relaxed and caring environment. I offer a variety of dental services from which kids, parents and grandparents can all benefit.

Dr. Jorge Hernandez

Originally from Colombia, I moved to the Fox Valley in 2007, where I graduated from Marian University with a degree in Biology. Shortly after, I pursued graduate studies at the University of Wisconsin Oshkosh in Microbiology and Biotechnology, followed by earning my Doctorate from the University of Minnesota School of Dentistry in 2019. After graduation, I wanted to return to my roots in the Fox Valley, where I currently live with my 9-year-old son, Jacob.

My experience has helped me grow as an individual, a professional, and a leader. I practice dentistry that focuses on patient experience and gentle, holistic care while investing in my team and the community. This led me to join Dr. Ryan’s team serving the Oshkosh and surrounding communities. In my free time, I love to spend quality time traveling, hiking, and camping with Jacob and my partner, Megan.
