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 a local practice for 3 years before opening Arizona Mohs Surgery & Dermatology in 2020. In Tucson, he and his team have performed 17,000 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.

We are most grateful for the extraordinary skill and care you demonstrated when performing surgery last week. We are pleased beyond measure with your expertise.
Just a brief note to express my satisfaction with the outcome of the surgery thus far. I appreciated you taking time out of your busy schedule to answer my questions. Also, I want to compliment your staff because they're so courteous whenever I call and they're so helpful. I recommended you highly to a friend who is now considering surgery on her face. She sees a doctor at UK but I said she should consider using your services. In short, I'm glad I put my face in your hands.
Thank you for the opportunity to spend time in your practice learning about Mohs surgery and more particularly the art of reconstruction. I sincerely appreciate that you tailored your teaching to my future plans. You are the only professor to have done that so far. This week has given me a great deal of insight into future standards for appropriate skin cancer treatment and management. I look forward to a day when I will be honored to call you a colleague.
Thank you for doing a great job on getting cancer off my eyelid and out the corner of my eye. It has healed well! Every one of you in the office treated me well and took good care of me and I really appreciate that. I'm very pleased that my eye is alright and I hope you can see how is has healed. Thank you so very much!
Everyone was extremely pleasant and helpful. All procedures were explained in detail which made the experience comforting. This is a wonderful group.
It has been a little over a week since my last subcision procedure and things are going and looking great! I want you to know how much I greatly appreciate your help, kindness, and concern. You are one of the few doctors who leaves you with the pleasing impression that they honestly care about their patients.
I feel like the luckiest person on earth that I was sent to you. You have the lightest touch while working, but the determination to get things right like a 5 Star General. You are rare.
I wanted to take a few minutes to again thank you for the amazing job of cancer removal and ear reconstruction. The work that you and your team did is amazing.
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!
Thank you so much for the great job that you did for me. I greatly appreciate all that you are and all that you do. Your staff was wonderful and I was impressed with your care, humor, and confidence and of course your skills. I felt very comfortable and in great hands.
