Lydia PatientFinding the source, not covering symptoms
Functional medicine seeks to identify and address the root causes of disease. It views the body as one integrated system, not a collection of independent organs divided up by medical specialties.
Symptom-focused care
- Covers symptoms with medications
- Treats disease once it occurs
- Separate organs, separate specialists
- The same approach for everyone
Our root-cause approach
- Finds the source of the problem
- Improves your health to reduce the risk of pain and illness
- Treats the whole system, not just the symptoms
- An individualized plan built around your story



Dr. Steven Osterhout, DC, CCN
At 12, Dr. Osterhout was diagnosed with Type 1 Diabetes, and at 20 he underwent open heart surgery. Facing two profound health challenges so early in life created an overwhelming need to find out why we become, and remain, sick.
That question became his life's work. A Portage native, he has helped thousands of patients since founding Vitality Healthcare in 2004.
