Dr. Kate enjoys treating families from a newborn to your grandparents.  Dr. Kate has a passion for sports injuries. Dr. Kate is an athlete herself and enjoys waterskiing in the summer. She competes at the state, regional and national level. Being an athlete, Dr. Kate understands the injuries (being injured herself) and the drive to get back into the sport along with the importance of maintaining peak performance for the sport. Dr. Kate also focuses on nutrition and teaching the importance of good nutrition in regaining and maintaining optimal health, not only for the athlete, but for the non-athlete. 

Dr. Kate's interests include spending time with her family, Tobi (her dog) and friends, hiking, crafts, biking, gardening, reading and water-skiing.

Outside of the office she enjoys being with her family, church activities, gardening and crafts. She also has a passion for animals.


Tobi – Office Dog/Greeter

Tobi has been with the clinic since 2015 and her job is to greet patients at the door. She plays with the kids and adults and helps to calm them down before their adjustment.
