Training Through Practice

The Lifestyle Medicine Observer Program offers hands-on training in lifestyle medicine, natural remedies, culinary coaching, hydrotherapy, and botanical treatments that you can offer your patients. All these practical classes are offered on the premises of Wildwood Lifestyle Center.

Shadow a Medical Provider

One of the best ways to learn lifestyle medicine is through observing those who practice it. Part of the Observer Program is shadowing various medical providers as they prescribe natural remedies and lifestyle change to real patients who walk into the Wildwood Clinic. Our providers include licensed medical doctors and nurse practitioners. The rest of our team includes massage practitioners, hydrotherapists, licensed mental health counselors, chaplains, a nutritionist, and lifestyle educators.

Customized Guest Lectures

Depending on your specific interests, our team works to invite leaders and pioneers in lifestyle medicine and natural remedies. They can answer your questions and share invaluable experience during guest lectures.

Surrounded by Nature

Wildwood Health Institute’s campus is positioned in between Lookout Mountain and Raccoon Mountain that both provide beautiful places for recreation. Wildwood’s own campus also has miles of beautiful hiking trails available for anyone residing on its premises.
