Dr. Kathy Zelken is returning as an aesthetic medicine provider after a hiatus since the birth of her daughters. She has served as the medical advisor of the Zelken Institute for Aesthetic Medicine since it was established in 2016. She has worked tirelessly in the background to ensure the highest level of excellence and quality in all aspects of patient care. She has had a keen eye for artistry since childhood, starting from being a classically trained artist. She graduated summa cum laude from the University of California Berkeley with a major in Molecular and Cell Biology and a minor in Art History. During medical school at the University of Texas Southwestern, she published papers with world-renowned plastic surgeon and former editor-in-chief of Plastic and Reconstructive Surgery journal (the top journal in the field), Dr. Rod Rohrich. Her meticulous nature, extraordinary calmness, and friendly demeanor gained from close to a decade of working as a board-certified pediatrician in Orange County and doing some of the most delicate procedures on tiny babies will put the most anxious patients at ease. She is thrilled to help patients map out a comprehensive treatment plan to achieve their individual aesthetic goals and explain various nonsurgical procedures in detail. Her patients love her and seek her out for neuromodulator and facial contouring injections, skin rejuvenation, laser treatments, and so much more.
