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.

Thank you for your kindness. I wish I could put into words what your thoughtfulness means to us. I am so amazed at the things you have done for my husband and myself that you didn't have to do. It is very greatly appreciated.

Just a note to thank you for my surgery. The graft has taken well and it seems to be healing nicely. Since I was diagnosed with myeloma and lymphoma, I have been treated by a number of doctors and surgeons. You have been one of the very best. You were friendly, took time to explain things in easy-to-understand terms. You are a very skilled surgeon. I was treated more as a friend, not just another number. It's never fun to go to doctors, but you make it as enjoyable as possible. Thanks.

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 guess that is what makes your so special. And for all the phone calls you have made, checking on me after surgeries, that means the world to me. I just hope you and your staff realize how special you are to me and my family. Without you, this journey might not have lasted this long. Thanks for everything in helping me fight this disease.

I wanted to thank you and your staff for taking such good care of me when I visited the surgery center. I was happy to be treated so kindly and really appreciate that your nurses went out of their way to make me comfortable and help accommodate me with my modesty / religious preferences. Thank you.

Just wanted to say thanks, even though very late, for the excellent procedure you did on my face (left side).  It is practically invisible.

Words can never convey the depth of our gratitude in the treatment of our mother. Going the extra mile with follow-up phone calls and the prayers were greatly appreciated to relieve our fears and concerns. The kindness and compassion that was shown to her and even to us was so deeply felt. Thank you and your staff for everything.
