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 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.

I want to thank you for your superb professionalism, kindness, and huge heart.  You made my experience through the Mohs Surgery bearable, you explained in detail what to expect, and you calmed my racing heart. It took 3 attempts to achieve clear margins and while I was waiting, the staff was nothing but excellent, caring, and reassuring.  You have an A Class Facility.

I wanted to say thank you to you & your staff for the successful removal of the BCC from my forehead.  The wound healed nicely & is not noticeable.  I appreciated how you shared in advance the details on how you perform Mohs surgery.  I enjoyed you sharing your interest in sports cars and racing.

I just wanted to tell you again what a wonderful job you did on my face. As you said it would, each month it gets better and better. If you did not know me, you would never notice it. I am sending this picture so you can see for yourself. Maybe you can put in my file next to the ones that I look beat up in. Ha. Anyway, I really appreciate all of you, not only the great work you do but the care and kindness you showed me. It meant more than you will ever know. Love,
