Holistic ICON provides real solutions to patients suffering from chronic health conditions using holistic, patient-centered, precision-based functional medicine. We work in partnership with their primary care providers and other health care specialists to optimize their health and quality of life.

We do not just treat symptoms with medications. Instead, we focus on identifying and treating the root causes of our patients’ illness. Then, we collaborate with our patients to develop a personalized treatment plan and empower them to incorporate long-term prevention and wellness strategies to ensure optimal health, wellness and disease prevention.

Experts in Functional Medicine

We address the underlying causes of our patients’ health problems instead of just treating symptoms so they can get well and stay well without unnecessary drugs or surgery.
