Georgia Dermatology Center has now partnered with Olansky Dermatology & Aesthetics. This partnership gives our patients added confidence and convenience when choosing the right source for their skin-related medical needs.

Our acclaimed providers, staff, and top-tier level of service will remain the same, Dr. Gross will be here to lead the charge at our Cumming office. We will continue to provide our patients with the same quality care and excellent service that has made us the “Best of Forsyth” for eight years in a row.

Georgia Dermatology Center’s suite of services will be increased by several additions. These include Mohs surgery, an advanced surgical procedure that removes skin cancer effectively using only local anesthesia. Additionally, this partnership will allow our patients to take advantage of a larger group of accepted insurance options. This widens the scope of patient access without incurring out-of-network fees.

The end result of this merger will only heighten patient care, and that our primary mission.
