Dr Navin Arora


Dr. Navin Arora is a native New Yorker and founder of Borealis Dermatology. He has over 15 years of experience providing comprehensive dermatological services and compassionate, personalized care to patients.

Borealis Dermatology was created and launched to meet Dr. Arora’s vision and goal of providing comprehensive dermatologic services to patients on Long Island and across the New York region. The practice offers state-of-the-art medical, surgical and cosmetic services.

Dr. Arora has an extensive professional background having served in a wide range of roles at the clinical and leadership levels within the U.S. Department of Defense (DOD) and private sector. He proudly served as an U.S. Army physician for 12 years in operational theaters around the world and provided care to active-duty military and civilians as part of humanitarian missions.

Dr. Arora’s unique background has allowed him to diagnose and treat a broad spectrum of skin, hair and nail diseases, in all cases of severity and across all ethnicities. The extensive medical DOD formulary allowed him to develop and refine his ability to diagnose, treat and provide effective follow-up or referrals. As a result, Dr. Arora is often sought after as a second opinion and managing complicated cases.

He has provided healthcare services in a variety of settings, including on the federal level, non-profit integrated health care systems, with private equity and non-private equity-owned practices. He understands the complexities of health care, but always puts patients and their wellness first. 

Dr. Arora enjoys treating children of all ages. As a father of three, he understands the questions and concerns parents and caregivers can have.

Throughout his academic and professional career, Dr. Arora authored numerous articles in medical, surgical, and cosmetic dermatology journals. In addition, he is a Clinical Assistant Professor at the Ronald O. Perelman Department of Dermatology at NYU Grossman School of Medicine. He lectures and volunteers to teach NYU dermatology residents.
