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, Taylor Foxworthy, PA-C, and Tabitha Bayne, PA-C, joined our experienced team from 2024-26.  Shelby has practiced medical & surgical dermatology in Tucson since 2018, and Taylor has worked in both dermatology and pediatrics. Tabitha has practiced Dermatology since 2015 at Massachusetts General Hospital, Tucson, and then Oregon.  They also previously all worked together at another local practice.  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 wanted to take this opportunity this opportunity to thank you all for taking care of me before, during, and after my Mohs surgery.  The customer service, compassion, and kindness of every single staff member was absolutely stellar and you should be incredibly proud of your dedication to the patient!

While it's never fun to have surgery, the staff at Arizona Mohs Surgery make it the best possible experience.  I hope that I'm forever cancer free but if I have to have more surgery, thanks to your team, I won't go into it with fear and trepidation.

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,

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 want to thank you for the professional way you handled my surgery. In the last ten years, I have had ten surgeries but I have never been treated with more professional, kind, and courteous service as I received from you and your staff. You took your time to explain all procedures and what I could expect from you. Thanks a million and I wish you continued success in your practice. I'm sure you will be able to make a lot of people happy. Keep up the good work. Your happy patient.
