What is functional medicine?

Functional medicine goes well beyond just treating symptoms. It is medicine focused on the how and why an illness occurs. By identifying the how and why, we are able to give patients with chronic illness something they are missing—Hope.

My Story

Amy Bull, PhD, MSN, FNP-C, has over 20 years of primary care experience and is a Functional Medicine provider.

After suffering with chronic joint pain since childhood, I finally found the practice of functional medicine. I had suffered for years and had been taking medications, gone to physical therapy, had regular massage, and had epidural steroid injections to try and help relieve my symptoms. Frustrated with the lack of long-term results, I decided to take a different approach. I started a gluten free diet. Then, my pain stopped!


Once my healing started, I realized I had found a new way to practice medicine—functional medicine. While I was a professor, I decided to go back to school through the Institute of Functional Medicine that is affiliated with Cleveland Clinic. I left my teaching position and transitioned to full-time practice and started offering functional medicine to interested patients…


I believe in functional medicine because it is the medicine of ‘why,’ not ‘what’. Why is this patient experiencing pain? The answer is to find the ‘why.’ Sometimes it’s simple; Sometimes, it involves some new tests that haven’t been done. Mostly, it involves a deep commitment on the part of the patient to change their life, no matter what it takes. My commitment is firm…to help them get there!”
