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.

Thank you so much for the wonderful care you and your staff gave me. The removal of my skin cancer was a breeze. I appreciated the straightforward information and genuine care. I hope dealing with my insurance is not too big of a headache for your staff. I am thankful they were willing to go an extra mile to get my visits approved. If I am lucky, my employer will realize you are the best choice for their dermatology services. That way, I can continue to have the excellent care you give.

Thank you for all your help. I also wanted to compliment you on your kindness and great attention to detail. You always make time to talk and made me feel at ease through a tense procedure. I have been to many doctors in my life and would rate you as the best I have ever known. Your attentiveness, compassion, and ability are without any possible reproach. I can actually say I looked forward to my doctor visits rather than avoided them. I wish you continued success.  Thank you truly.

I just wanted to drop you a line to tell you how happy I am concerning the care you gave me.  I tend to be quite critical of everything from medical service to cereal box design.  I even rate things on the traditional A to F scale.  I have never rated anything an A plus but Mohs broke through!

The lovely ladies at the front desk could not be more accommodating.  They make you feel comfortable and they're so pleasant!  Your surgical assistant was so incredibly professional, but warm and friendly.

My contact with your office with questions about the procedure was greeted with full explanations and a courteous spirit.  Warmth without professionalism leaves one uncertain; professionalism without warmth leaves one uncomfortable. Gladly, you and your staff combined both warmth and professionalism.
