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 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.

A young lady at the entrance greeted me in such a friendly manner that the expression on her face, her posture, and her words caught my attention. The instructions are also striking: "you may bathe", "please try to stop smoking", "we would prefer", "please perform a few days", "please be patient as you heal." And finally, "We wish you a speedy recovery." These instructions come from doctors and nurses who are authorities in dermatology. Yet, they are delightfully modest.

Your patience, time, and care are greatly appreciated. I am so absolutely pleased with my leg that now each and every day I am able to look at it, and for once, to not be ashamed of the scars that were once there. Thank you so much. I will always be grateful to you.

Three days have passed since your removal of the cancer from my face.  The pain from the surgery has been light and tolerable.  There has been no need for pills to relieve this pain.  There are no signs of bleeding or of swelling.  You mentioned the danger to a nerve which controls the mouth, had the cancer not been removed.  The body is wonderfully made!  It has never occurred to me that there is a mechanism which enables us to open our mouths.
