Providing Personalized and Innovative Medicine

to Advance Health and Well-being.

The Evergreen Centre offers a unique group of integrative medical doctors with a referral network of some of the best trained integrative practitioners and conventional medical specialists available.

Our traditional primary care is extended with a deep commitment to nutritional, functional and holistic medicine.

Dr. Steven Johnson, Medical Director, began his journey over 21 years ago as a pioneer in the field of integrative medicine with a special interest in Rudolf Stiener's philosophy on the connection of rational spiritual medicine to health. Dr. Johnson trains and educates integrative doctors, nurses and health practitioners around the world.

Our philosophy is based on respecting the synergy between a healthy mind and body. When a person is healthy they can be imaginative, inspired and better able to achieve their creative goals. This includes aging with dignity and ageless potential.

In our practice we offer genetic testing for cardiovascular disease, metabolic deficiencies and drugs sensitivities as well as advanced functional testing for hormone imbalances, food sensitivities, digestive problems, toxic exposures, infections and nutritional deficiencies. We are deeply committed to finding individualized solutions to problems by listening to your history, biography and personal issues which may be impacting your health. Often, finding ways to address or support these circumstances can improve our health and lives.

The Evergreen Medical Centre has been a pioneer in several areas of integrative medicine including Intravenous nutritional therapies to extend cardiovascular, autoimmune, neurological and immune support. We have also brought expertise to Kentuckiana in the field of prolotherapy, prolozone, platelet rich plasma and bio-regenerative-fat cells for joint, tendon and musculoskeletal injuries to the Kentuckiana region. We strive to find the safest and best way we can to support your health in a caring environment.

We currently accept Medicare and United Health Care insurance. If you are not covered by Medicare or United Health, we will file out of network insurance claims with your provider for you. **For patients with high deductibles we offer a program for major lab discounts.
