Dr. Mendenhall, who is often described as compassionate, knowledgeable, and a good listener, is comfortable bringing the best of all worlds to her patients—from the very natural to the targeted medical, and everything in between. As a naturopathic doctor, she can prescribe both natural and prescription medications. Dr. Mendenhall’s approach always starts with the basic, but often missed, tenets of medicine: First, do no harm, treat the cause, and listen well.
When she isn’t practicing medicine, she can be found hiking in the woods with her husband, daughter, and shepherd-corgi mix, scanning the ground for wild herbs and mushrooms.
