Professional Staff



After 15 years in aesthetic medicine, we have adopted a holistic theory that utilizes technology, injectables, specialized treatments, and products to deliver optimal results. The objective should be natural and rejuvenated skin. Unfortunately, there is no fountain of youth, silver bullet, or magic product to create younger, healthy skin.  However, a thoughtful, integrated approach that incorporates the right services and products can make a significant impact for change and prevention. We believe the people delivering that guidance and performing those procedures are equally as important.  The Skin Thesis® staff is made up of board certified Nurse Practitioners, Registered Nurses, and Physician Assistants.   Our practitioners are trained to listen and spend ample time consulting with our clients to develop the appropriate blueprint.
