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 joined our experienced team in 2024.  Shelby has practiced medical & surgical dermatology in Tucson since 2018.  She is an expert 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.

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.

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.

I know you don't remember me, but you removed a skin cancer from the side of my nose. I jokingly asked you to make me beautiful.  My nose looks wonderful!  You have to look very carefully to see you incision. I am very happy and pleased with my nose. You and your staff treated me with so much care. I really appreciate it. Something that was so scary to me was handled so that I felt reassured and comfortable. Thank you for your care of me.  Affectionately, your patient.
