In addition to Mohs surgery, we offer Comprehensive Skin Cancer & Dermatologic Care at AMSD, including skin cancer screenings, biopsies, non-Mohs excisions, curettage, and topical therapy for cancers that may not need Mohs surgery. These services are provided by Shelby Coplen, PA-C, Taylor Foxworthy, PA-C, and Tabitha Bayne, PA-C: three highly-trained and experienced Physician Assistants who previously practiced together and then joined our team in 2024-26. Shelby, Taylor, and Tabitha are also experts in the treatment of rashes, psoriasis, rosacea, and acne. Shelby is available on Monday, Tuesday, Thursday, and Friday from 7:30 am to 3:45 pm. Taylor works on Tuesday to Friday from 7:30 am to 3:45 pm. Tabitha cares for patients on Tuesday, Wednesday, and Friday, from 7:30 am to 3:45 pm. Please call us at (520) 612-7722 to schedule an appointment. We look forward to taking excellent care of you.
If you already have an established relationship with a trusted dermatologist, we are happy to address just cancers needing our specialized Mohs surgical services.
Please note that our clinic does not specialize in cosmetic services or disorders of hair and nails.
