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.

Best medical experience ever had. Thanks, Doc.
I would like to thank Dr. Dhir who is as good as it gets in giving patient care. In this day and time when health care is criticized for various reasons, it is very refreshing to have an organization such as yours doing it the right way. Since my experience with your people, I feel very good about health care and will let others know that you are not only dedicated to your craft but are also dedicated to your patients. Thank you again for making this a very pleasant experience.
Thank you so much for the wonderful care you and your staff gave me. The removal of my skin cancer was a breeze. I appreciated the straightforward information and genuine care. I hope dealing with my insurance is not too big of a headache for your staff. I am thankful they were willing to go an extra mile to get my visits approved. If I am lucky, my employer will realize you are the best choice for their dermatology services. That way, I can continue to have the excellent care you give.
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.
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.
While it's never fun to have surgery, the staff at Arizona Mohs Surgery make it the best possible experience. I hope that I'm forever cancer free but if I have to have more surgery, thanks to your team, I won't go into it with fear and trepidation.
I just wanted to let you know how much I appreciate the care, concern, and compassion you showed me yesterday when I was in for surgery. Thanks so much for explaining everything to me and for being so thorough. You have a wonderful manner about you and you really set my mind at ease. Your willingness to allow me to call you at home put you over the top! I have great respect for you and will not hesitate referring others to you. Thank you again for sharing your gifts with me.
Thank you all for your care and expertise during our recent skin surgeries. Everything was really appreciated for our speedy recoveries.
A young lady at the entrance greeted me in such a friendly manner that the expression on her face, her posture, and her words caught my attention. The instructions are also striking: "you may bathe", "please try to stop smoking", "we would prefer", "please perform a few days", "please be patient as you heal." And finally, "We wish you a speedy recovery." These instructions come from doctors and nurses who are authorities in dermatology. Yet, they are delightfully modest.
