Quality, Experience, and Compassion
Dr. Anir Dhir was born in Detroit to immigrant parents from Germany and India. After graduating with a B.S. in Biomedical & Electrical Engineering with honors from the University of Texas at Austin, he attended Baylor College of Medicine, where he was inducted into Alpha Omega Alpha - the medical honor society. He completed his Dermatology residency at Emory University in Atlanta and then pursued a fellowship in Mohs surgery and facial reconstruction in Birmingham, Alabama with world-renowned Gary Monheit, MD – a Tucson native and Past President of the American College of Mohs Surgery, American Society for Dermatologic Surgery, and American Academy of Cosmetic Surgery.
From 1999 to 2015, Dr. Dhir was a partner with Dermatology Associates of Kentucky in Lexington. He was the busiest Mohs surgeon in Kentucky, where he performed 30,000 Mohs surgeries with a cure rate of over 99.5% and an infection rate of 0.2%. He served as the Medical Director of the only Medicare- and AAAHC-accredited ambulatory surgery center (ASC) ever built in Kentucky dedicated to dermatologic surgery. In 2003, Dr. Dhir was first elected to Best Doctors in America by his colleagues - an honor awarded to the Top 4% of U.S. Physicians. Since 2004, he has also been recognized as a Castle Connolly Top Doctor - a recognition given to only 7% of all U.S. board-certified physicians. Dr. Dhir has authored several publications and served as faculty at numerous national scientific meetings. He has been interviewed as a dermatologic expert on ABC, CBS, NBC, PBS and in publications such as Newsweek. Dr. Dhir was first board-certified by the American Board of Dermatology in 1998 and has been a Fellow in the American College of Mohs Surgery since 1999. He also carries subspecialty board certification in Micrographic Dermatologic Surgery.
After raising their children, Dr. Dhir’s love of the Southwest and recognition of Tucson’s skin cancer epidemic led him and Nathalie to relocate to Tucson in 2017. Dr. Dhir practiced with HealthySkin Dermatology for 3 years before opening Arizona Mohs Surgery & Dermatology in 2020. In Tucson, he and his team have performed 13,000 Mohs surgeries. His goal is to use his significant Mohs surgical and ASC management experience to deliver compassionate, ASC-level surgical care in a less expensive, more comfortable office setting.

Thank you for the surgery on my right eye area + the kind + wonderful way you and your staff treated me. I was upset for being late and you all made me so relaxed and welcome. My sincere thanks.
I want to thank you for your superb professionalism, kindness, and huge heart. You made my experience through the Mohs Surgery bearable, you explained in detail what to expect, and you calmed my racing heart. It took 3 attempts to achieve clear margins and while I was waiting, the staff was nothing but excellent, caring, and reassuring. You have an A Class Facility.
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 Dr. Dhir for taking good care of me. I am healing nicely! You are a great surgeon. So kind and thoughtful. I highly recommend you to anyone and your staff.
AT is doing fine. I just wanted to thank you for all your kindness. You were super in my eyes. We will never forget you all. God Bless you all.
I appreciate your generosity in allowing me to observe you at work. This was very educational, and now I feel I can properly inform patients about the expected experience when undergoing Mohs surgery. It is clear to me what an elegant, accurate, and effective method to excising skin cancers. I am impressed with the way your clinic is run. The nurses and staff are very professional and responsive to the patients which I’m sure they appreciate. I hope to see you in the future!
When it comes to being a great doctor, you more than fill the prescription. I'm so very fortunate to have you for my dermatologist.
Thank you for a successful Mohs surgery. I was very confident in your abilities and it was a pleasure to meet you.
I feel that my surgery experience was much more pleasant than I had expected because of your expertise along with your gentle, caring nature. You can't know how much that unexpected phone call meant to me. Comments from family and friends have been that they cannot believe that it has been only a week since the surgery when they saw my forehead. I think they consider you a magician, too!! I hope I never need this type of surgery again but will not be concerned. Thank you.
Dr. Dhir, Wanted to show my appreciation for the excellent care I received last month! Thank you so much!!!
