Mohs surgery

Mohs micrographic surgery is the gold standard of treatment for many basal cell and squamous cell skin cancers, especially those located in areas where it is vital to spare as much normal skin and tissue as possible. Dr. Galloway first removes the tumor and a very small margin surrounding it. The tissue is then processed in an onsite lab while you wait, and she evaluates the pathology under a microscope. If there is any remaining skin cancer, Dr. Galloway maps out the residual tumor, removing additional skin only from that location. This process is repeated until all the skin cancer has been removed.


Dermatologic Surgery

Many types of skin conditions are treated with surgical excision. This includes benign growths such as cysts and lipomas as well as abnormal moles. Some skin cancers are also best treated by surgical excision. During surgical planning, Dr. Galloway will determine the amount of surrounding skin to be removed. Surgical procedures are performed in the clinic setting under local anesthesia.

cosmetic procedures

Dr. Galloway offers a variety of facial rejuvenation procedures that enable patients to look and feel their very best, including Botox, fillers and chemical peels.
