Mohs Surgery and Cosmetic Surgery & Laser Fellowship programs

ASDS AccreditationEach year, SkinCare Physicians trains board eligible dermatologists in its Cosmetic Surgery and Laser Fellowship program which is accredited by the American Society for Dermatologic Surgery (ASDS). One of these fellows is also trained more extensively in Mohs surgery under a fellowship program approved by the American College of Mohs Surgery (ACMS) and also certified by the Accreditation Council for Graduate Medical Education (ACGME). The programs are under the direction of doctors Kenneth A. Arndt, Jeffrey S. Dover, Michael S. Kaminer, and Thomas E. Rohrer. All are internationally recognized experts in their field.

Dr. Kaminer explaining the Aveli cellulite device to two FellowsFellows receive a broad exposure during the twelve month fellowship to all aspects of cosmetic and dermatologic surgery, as well as laser medicine. This includes hands-on experience in procedures including injection of soft tissue fillers such as Restylane®, fat transplantation, use of botulinum toxins, sclerotherapy and endovenous vein ablation, liposuction, Contour Threadlifts, and laser resurfacing.

The fellows also spend a good deal of time during the year working with our Mohs surgeons, Doctors Rohrer and Kim, perfecting technique and skills in dermatologic surgery. In addition, the fellows receive in depth hands-on experience with the over twenty lasers and related devices present at SkinCare Physicians. The devices include Intense Pulsed Lights, Q-switched and long pulsed Alexandrite lasers, Q-switched and long pulsed Ruby lasers, Q-switched and long pulsed Nd:YAG lasers, Pulsed Dye lasers, KTP (532nm), mid infrared lasers, and CO2, Erbium and fractional lasers for resurfacing and rejuvenation. Some of the other technologies include radiofrequency, LEDs, and plasma devices. The fellows have the opportunity to use the latest technology available anywhere in the world.

By the end of the fellowship year, fellows have acquired the knowledge and skills necessary to perform all of the above procedures, and have a tremendous amount of hands-on experience with all of them. One recent fellow wrote: “What an incredible year![…] I am so excited by how much I learned from the nuances of surgical and cosmetic dermatology, to the art of dealing with patient, to the business of practice management. […] This year has completely transformed my practice of dermatology, and I am forever grateful.”

She completed her dermatology residency at Northwestern University, where she served as Chief Resident of Cosmetics and Chief Resident of Recruitment. She earned her medical degree from Johns Hopkins University and before that graduated summa cum laude from Washington University in St. Louis.

Her research has explored topics ranging from laser use in skin of color and body contouring to the effects of pregnancy-related hormones on the skin. She enjoys staying at the forefront of new technologies while approaching cosmetic treatments with a thoughtful, individualized philosophy: the best results should help patients feel like the most confident version of themselves.
