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.

My husband had his hand operated on by Dr. Dhir , using the Mohs technique, back in the spring and doesn't even have a scar!! Not only is he a wonderful surgeon, but a super nice person!! Everyone there was great!!
It is a miracle to look at Gordon and not see the large, red, and very irritating sores that were there. Dr. Dhir did the surgeries…I thank God and Dr. Dhir and his assistants for their most patient, kind, and loving treatment of Gordon. He is a special person and I know God has helped us to get this far with his recovery from a most dramatic period in his life.
Thank you for sharing with our Young-At-Heart group. We gained much knowledge from your informative presentation. Your enthusiasm and individual attention will stay with us a long time. The ladies are using the cream and they are praising it highly. Thanks again for giving your time to talk to us.
Merry Christmas and a Happy Holiday to you! I thank you so much for your thoughts, prayers, and wonderful cards. There is not another doctor like that. You care! That is wonderful.
Thanks for your friendly service provided by your staff and the best and most efficient healthcare from the heart of one of the most prestigious physicians in Dermatology.
I wish to thank the staff for being so nice, kind, and patient with me. All were just great!
Thank you for all your help. I also wanted to compliment you on your kindness and great attention to detail. You always make time to talk and made me feel at ease through a tense procedure. I have been to many doctors in my life and would rate you as the best I have ever known. Your attentiveness, compassion, and ability are without any possible reproach. I can actually say I looked forward to my doctor visits rather than avoided them. I wish you continued success. Thank you truly.
Thank you all for being so kind, compassionate, and caring.
You pros did a dandy job on my surgery this month: no pain, no bleeding, no scar, no bad news. :-)
