We recently had the opportunity to learn more about Dr. Stewart, his approach, and the path that led him to become a board-certified and fellowship trained Mohs surgeon.
What made you decide to pursue a career in dermatology? What did the path to get there look like for you?
My journey to dermatology began with a deep interest in cancer biology and a desire to make a tangible difference in patients’ lives. Before starting medical school, I entered a PhD program in cancer biology, focusing on the molecular mechanisms that drive tumor growth and resistance through the regulation of cell-to-cell adhesion. Two years into the PhD program, I began medical school and continued both tracks concurrently for several years, completing my PhD just before my final years of clinical rotations in medical school.
During my dermatology residency, I was introduced to Mohs micrographic surgery, a field that perfectly combined my passion for oncology, surgical precision, and patient-centered care. Following residency, I completed a fellowship in Mohs surgery and cutaneous oncology.
What is your favorite aspect of being a Mohs surgeon?
The most fulfilling part of my work is helping patients heal from skin cancer while achieving the best possible cosmetic and functional outcome. Each case requires a balance of precision, problem-solving, and artistry. I also value the ongoing relationships I build with my patients—seeing them through treatment and following them for years after.
What is your approach to treating your patients?
My approach is grounded in empathy, education, and precision. I want every patient to understand their diagnosis, their treatment plan, and what to expect at each step. I know how important it is for patients to feel informed and reassured, and I take time to answer questions, explain pathology findings, and ensure each patient feels heard and supported from consultation through recovery.
What is your number one tip when it comes to taking care of your skin?
Sun protection cannot be overstated. I recommend daily use of a broad-spectrum sunscreen with SPF 30 or higher, protective clothing, and avoiding peak sun hours when possible. Just as important is early detection: perform regular self-skin checks and schedule annual professional skin exams. The earlier we catch skin cancers, the easier they are to treat successfully.
What is one thing you want your patients to know about you?
I approach every surgery and every patient with the same care and attention I would give my own family. Behind every biopsy or surgical site is a person who deserves compassion and clarity. I take pride in providing meticulous, evidence-based care and in helping my patients feel confident and comfortable throughout their treatment.
What do you like to do when you are not in the office treating patients?
When not in clinic, I enjoy spending time with my family, hiking in the White Mountains, running, and mountain biking – all with appropriate sun protection, of course!
