About Me

As a family medicine physician, I provide a holistic, evidence-based approach to conventional medicine. I incorporate vitamins and supplements while working closely with patients to facilitate positive lifestyle and dietary changes. I am very passionate about helping my patients achieve the optimal level of health and independence that comes with reduced prescription medications and weight loss. I have helped many of my patients improve the state of chronic conditions and even exceed their health care goals. I believe everyone is capable of improving their physical and emotional health dramatically with the right evidence-based care and dedicated support.

I enjoy working at The Ohio State University Wexner Medical Center because of the access to a vast network of resources and research. At The Ohio State University Center for Integrative Medicine, I've learned that the most effective path to wellness is through what we call "life-changing medicine," which works to align lifestyle and behavior for the achievement of optimal health.

When I’m not working I enjoy spending time with my family, practicing yoga and meditation, gardening, swimming, enjoying nature and exploring new healthy recipes.

I love Dr. Giles. She is friendly, knowledgeable thorough, and provided the kind of information/expertise I was looking for (Ayurveda). This visit was specific to a health question/issue and not primary care. If she were to provide primary care, sign me up.

My provider is great, I know physical contact can be tattoo or weird in professional/or medical situations. However it can be really comforting when someone is dealing with a serious illness such as myself. All my other providers have basically given up on me. But not Dr. Giles hasn't give up on me, and a hug from her meant so much.
