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.

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
Your kindness and professionalism, as well as that of your staff, was very much appreciated. As a healthcare worker, I take pride in treating my patients like I myself would like to be treated. It is quite evident that you each do that for your patients, too. Such admirable qualities are hard to find. Thank you for the excellent care that you gave my mother. I will never forget your kindness and the kindness of everyone who also helped care for her.
I don't know anyone who says, "I'm so happy I'm going to the doctor today". However, your staff did an excellent job of making me very comfortable. I know I'm not the only patient and your call was appreciated. It brought back memories of my childhood and our family doctor. You are a good doctor and I would recommend your facility to anyone. I spent a lot of time with your staff and they support you with kindness and compassion. You made it an experience I can remember with fondness.
Thank you so much for taking such personal care of me. I appreciate all the consideration I was given, the organization, and the promptness of my treatment and your checking on me.
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!!
To you, my dear Dr. Dhir - your presence exudes experience and competence. You have an incredible gift of being personable (no more than that - charming), real, yet focused with an incredible work ethic.
Thank you so much for taking extra time out of your busy schedule to give us answers to our questions and concerns. You treated us like how I wish all patients could be treated in the health care system today. Thank you for your wonderful handiwork. EH was in the best of hands.
We just wanted to say thank you - not only for your professionalism and expert care - but for your compassion. I've never been blessed with a more competent physician and as you know, we've seen our share. There will be a special place in heaven for you but just know for now that there are people that owe your their life - but you already have our hearts! Bless you Doc! We love you!
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.
We so appreciate the care & kindness you have given us. We have told many friends about your wonderful staff & to have that large of staff & everyone being so awesome - amazing!
I want to thank you for the professional way you handled my surgery. In the last ten years, I have had ten surgeries but I have never been treated with more professional, kind, and courteous service as I received from you and your staff. You took your time to explain all procedures and what I could expect from you. Thanks a million and I wish you continued success in your practice. I'm sure you will be able to make a lot of people happy. Keep up the good work. Your happy patient.
