Mohs Surgery At Southern Marin Dermatology

At Southern Marin Dermatology, Mohs micrographic surgery is performed by Dr. Ashley Decker, a fellowship-trained Mohs surgeon with advanced training in cutaneous oncology and extensive experience treating complex and high-risk skin cancers, including Mohs surgery for melanoma. Dr. Decker is one of a handful of dermatologists in Marin County to be board-certified in both dermatology and Mohs micrographic surgery.

Dr. Decker’s approach reflects her years of experience working and teaching in an academic medical center—careful margin evaluation, advanced pathology techniques, and thoughtful surgical planning, while maintaining a strong focus on both functional and aesthetic outcomes, particularly for cancers in delicate areas such as the face and ears.

From the moment you schedule surgery through your final bandage change, your care is coordinated in one place. Cancer removal, reconstruction, wound care, and follow-up are all managed by our dedicated team, who knows your case and is with you every step throughout healing.
