After a tremendously successful 23-year OBGYN practice, Dr. Z’s relentless curiosity and drive led him to change his practice focus in 2006; from OBGYN to Cosmetic Surgery. He became a board-certified cosmetic surgeon in Milwaukee and launched Zelko Aesthetics.

From there, he began researching better ways to do body contouring. As a result, one of the top cosmetic surgeons in Milwaukee, Dr. Z, developed ZBodySculpt – the most complete body contouring offering in the country. ZBodySculpt became a hit in the world of cosmetic surgery, with Dr. Z performing thousands of ZBodySculpt procedures on patients seeking cosmetic surgery in Milwaukee, Chicago, and around the globe.
