Biography
As a family medicine physician, I treat patients of all ages and specialize in the management of chronic diseases such as diabetes and arthritis, as well as the treatment of acute conditions such as sprains, strains and soft tissue injuries. I take a comprehensive approach to patient care, and believe in helping patients thoroughly understand their condition and encourage them to engage in healthy lifestyles and promote their well-being.
At The Ohio State University Wexner Medical Center I have the opportunity to collaborate with a brilliant team of providers who are dedicated to serving our community. The people are what makes Ohio State a great place to work, and because we’re all passionate about our jobs, we’re able to create a friendly and caring environment for our patients.
In my free time I enjoy spending time outdoors and relaxing with my family.

Dr Clark always listens to my issues and concerns. We talk out what I am doing and work towards a goal.
Dr. Clark has been my entire family's doctor for the last twenty two years. Even before he was with OSU. He is an exceptional physician who listens to his patients. He always asks about my family and how everyone is doing even remembering my daughter got married. This may not mean much to the higher ups, but as a patient it means a lot. He remembers everything I've been through bells pasly, prostate cancer, significant injuries, diabetes. Always listens to what's going on with me, not everyone else who's had these issues. I really can't say enough about him, this is the reason our family has followed him for so many years. He is an amazing physician and a better person for caring so much about those he cares for.
Dr Clark is great and would recommend him to everyone!

Very good doctor for us older folks
Nothing bad.
Dr Clarke is excellent...very down to earth and easy to talk to, yet efficient and knowledgeable
Everything was harmonious.
Dr.Clark sits down on my level and we start out about my feeling, thoughts, question. Then he asks question and we go forward from there. A great listener.
He doesn't really "hear" me. All doctor wants is to give me a prescription and then I will go away. He isn't interested in solving the problem or finding out the root cause of my Issues. He is respectful but dismissive in his recommendations. Last three appointments he has repeatedly offered new "miracle drug", surgery and multiple referrals for other doctors. Doctor seems uninterested in tackling woman's complicated health issues.
All good
Caring, good listener, explains in detail and competent. I have complete confidence in Dr. Clark.
