Our Story

Old School Surgeon, New School Knowledge

A Modern Practice with a Personal Touch

As modern medicine has become more impersonal and rushed, many of us miss the days when physicians and staff took the time to provide kinder, higher quality, and more individualized care.

Dr. Dhir and his wife of 28 years, Nathalie Dhir, BSN, created Arizona Mohs Surgery & Dermatology to provide the best of both worlds: top-quality, experienced surgical & dermatologic care in a personable, attentive, cost-effective setting.

Arizona Mohs Surgery & Dermatology's team has worked together for many years, and is committed to compassionate care and the pursuit of excellence. We pride ourselves on attention to detail. Our dedicated staff looks forward to treating you with the same kindness, respect, and concern that we would extend to our own family and friends.

Outside of medicine, Dr. Dhir and Nathalie enjoy physical fitness and cooking, and spend as much time as possible with their two grown children, Joshua and Emilie, who both live in New York City. Dr. Dhir has also pursued an amateur career in automotive racing, and Nathalie has produced an award-winning feature film, Burning Kentucky.

Shelby Coplen, PA-C, and Taylor Foxworthy, PA-C, joined our experienced team in 2024-25.  Shelby has practiced medical & surgical dermatology in Tucson since 2018, and Taylor has worked in both dermatology and pediatrics. They are experts in skin cancer screenings, non-Mohs treatment of skin cancer, and treatment of rashes, psoriasis, rosacea, and acne.

Our facility was constructed using the highest quality, "Made-in-the-USA" components and local Tucson talent wherever possible. Over 94% of our building materials, furnishings, fixtures, and equipment is manufactured in the United States, with some surgical instruments and our Zeiss microscope sourced from Germany, Switzerland, and the United Kingdom. Other than our Apple iMacs and iPads, very few items were sourced from China and only when no other viable option was available. We would like to acknowledge the outstanding work done on our behalf by local businesses such as Eglin & Bresler Architects, Venture West Construction, Goodmans Interior Structures, National Bank of Arizona, Desert Lab Studio, AV Specialists, Stat Computer Services, Illuminations, Millwork by Design, Achilles, Aztec Flooring, Effective Signs, Hall Custom Painting, and Creative Printers. Many of these companies went the extra mile to achieve our Made-in-America goal.

Arizona Mohs Surgery & Dermatology demonstrates its commitment to community and country via support of several nonprofits, including Arizona Heroes Memorial, Los Charros Foundation (FFA and 4H), Therapeutic Riding of Tucson, the Jewish Community Center's Garden of Hope, Davis-Monthan Air Force Base, Camp Valor Outdoors, Wreaths Across America, and Angel Charity.

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.

I have worked at a hospital for ten years so I have a real insight to health care facilities. The minute I walked in your door for surgery, the better I felt. I would rate my experience with your staff as outstanding. The people who work at your facility are very good at what they do. I was treated by smiling, friendly faces who loved their job and love their patients. The whole staff were very professional but most importantly were very concerned and caring towards me as their patient.

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.
