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 27 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 joined our experienced team in 2024.  Shelby has practiced medical dermatology in Tucson since 2018.  She is an expert in skin cancer screenings, non-surgical 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.

How can I possibly explain how much you have meant to us. When you took the Hippocratic Oath, it must have had an addendum that covered care and compassion. You are truly special and I feel so blessed to know you.

I just wanted to thank you for your call Friday after my neck surgery. I greatly appreciate your concern. Even though skin cancer is considered to have a high cure rate, it is upsetting to find out that you have any kind of cancer. You and your wonderful staff have made a difficult situation easier to understand and cope with.
