Clinical Staff

Our staff, headed by Dr. Bill Johnson, is extensively trained in all aspects of cosmetic procedures and patient care. In addition to offering excellence in our treatments and procedures, we educate our patients about all of their options and discuss all potential treatment outcomes and side effects. This ensures that our patients have realistic goals and a thorough understanding of their treatment progress at all times. Finally, we continue to participate in clinical trials for new procedures, and work with equipment manufacturers and other suppliers with the goal of improving the treatment options available to the public.
