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.

Spending time with family and friends, cooking, and hiking
Fred so enjoyed visiting with you. He thought you all were pretty spectacular.
Just a brief note to express my satisfaction with the outcome of the surgery thus far. I appreciated you taking time out of your busy schedule to answer my questions. Also, I want to compliment your staff because they're so courteous whenever I call and they're so helpful. I recommended you highly to a friend who is now considering surgery on her face. She sees a doctor at UK but I said she should consider using your services. In short, I'm glad I put my face in your hands.
Dr. Dhir, you have a special gift that I'm blessed to have been a recipient of, and I want to thank you from the bottom of my heart for what you do and I hope you'll be around a long time to share that gift.
Your staff is amazing, so professional, caring, and kind. Should you ever find yourself in Maine during the Summer, I'd like to treat you to a lobster dinner. Thank you again for your amazing work.
Thank you for your thoughtfulness and compassion from the moment we met. I am very fortunate to have you as my Doctor and Surgeon.
Very professional, caring people. Will recommend to others.
In my observation, it is clear very little goes on in your office without distinct deliberation. It seems you have an exact process for everything – from the knock on the door while a patient is waiting to the language on the handout being exact, engaging, and grammatically correct. You are not only an outstanding surgeon, but an outstanding businessman/ manager/etc. It shows in your office and in your people.
Three days have passed since your removal of the cancer from my face. The pain from the surgery has been light and tolerable. There has been no need for pills to relieve this pain. There are no signs of bleeding or of swelling. You mentioned the danger to a nerve which controls the mouth, had the cancer not been removed. The body is wonderfully made! It has never occurred to me that there is a mechanism which enables us to open our mouths.
