The Lipo Dissolve Clinic, Chicago

In the July 2012 issue of O Magazine, Dr. Toni Bark is pictured wearing a bright purple shirt and black yoga pants, suspended on cobalt silks inside her bedroom. This is how she exercises. Of course, considering that she's an alternatively-minded holistic physician, this offbeat health regimen is no surprise. Dr. Bark also brings an unconventional approach and a prevention-based philosophy to The Center for Disease Prevention and Reversal. Here, she offers medical tests, homeopathic treatments, and nutritional services to help care for her clients and the variety of bodily systems coexisting within them.
