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, University of Arizona graduate, 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 and lack of timely access 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 15,000 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.

Dr. Dhir and Dani, can't truly express my appreciation of your skill and wonderful care during my recent Mohs experience. I so appreciate how I was treated by you both.
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.
Just wanted to send you a little note of thanks for being so kind and thoughtful when I had my minor surgery on Friday. It was so nice of you to call me after the surgery to see how I was feeling. I don't think I have ever had a doctor do that and it made me feel good. Thanks again.
Not only were the staff very kind and caring, but are a real credit to their profession. I was very impressed with the way they relate to their patients. Thank you for taking the time to explain everything to us. Your staff is very wonderful. You should be very proud of them.
Thank you for all your kind service, your happy smiles and care. Enjoy the sweets that are as sweet as all of you.
I have been reflecting on the minor basal cell surgery that you performed on me yesterday. I am extremely pleased with the professionalism and expertise of you and your staff, and the quality of your facilities. I will gladly recommend you and your facility to my family and friends. Again, thank you for helping me to feel comfortable and reassured during the stressful time.
Thank you for the excellent care I received on my visit from you and your staff…By the end of week two, you cannot tell where the surgery site was.
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 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.
Your patience, time, and care are greatly appreciated. I am so absolutely pleased with my leg that now each and every day I am able to look at it, and for once, to not be ashamed of the scars that were once there. Thank you so much. I will always be grateful to you.
