Meet the Dentists

Thomas Wieg, D.D.S.

Our very own 2015 Business Man of the Year has been practicing dentistry in Mariposa since 1984. Aside from his many educational and professional achievements, Dr. Tom enjoys hiking and photography, as well as looking forward to spending time with his first grandchild. When he’s not busy handling the complex dental cases of Yosemite Dental Care, he dreams of someday hiking the John Muir trail.

Timothy Wieg, D.D.S.

Since returning from practicing dentistry on Wall Street in New York City, Dr. Tim has been instrumental in guiding business growth and adoption of new technologies at Yosemite Dental Care. A Mariposa native, Dr. Tim also enjoys backpacking, travel, and cooking delicious food. Dr. Tim is excited to have his fiancé, Dr. Karen, working at his side, and he looks forward to being a father.

Karen Watanakeeree, D.D.S.

Since joining Yosemite Dental Care in June 2016, Dr. Karen has rapidly become one of the most loved and tireless forces in the office. Dr. Karen never steps down from a challenge, and she always goes the extra mile for her patients and co-workers. Dr. Karen is excited to raise her first child in Mariposa with Dr. Tim. She enjoys hiking, backpacking, running half-marathons, and all things Disney.

Linda Sah, D.D.S.

As a recent graduate from Loma Linda University, Dr. Linda brings fresh perspective and skill to Yosemite Dental Care. She is already stealing the hearts of Mariposians through her gentle spirit and love and care for pediatric patients. In her spare time, Dr. Linda loves playing the piano, soap crafting, cooking, eating, and exploring her new-found home.

Good oral hygiene is the core of Yosemite Dental Care. In our hygiene-focused practice, it is difficult to make it through the door without some thorough attention from one of our skilled hygienists. All of our hygienists hold your oral health as their top priority, and they work seamlessly in conjunction with our doctors in facilitating your first and regular visits to our office.

Yosemite Dental Care offers Zero Dollar Out of Pocket hygiene services (including cleanings, check-ups, x-rays, and even deep cleanings) to all of our patients. We bill insurance of those patients who have it, but we do not charge those without insurance -- approximately 55% of our patient family! Our goal is to remove all barriers which could stand between you and the basic standard of oral health. Contact us for your free cleaning today!

Very attentive and personalized to his patients. Clearly explained the procedure prior to and explained potential symptoms of discomfort after. Very pleased with care, performance and overall experience.

His professional work has helped us maintain superb oral health while enjoying his personable approach. He has made a large contribution to our professional community and we are very grateful.”
