FoxHall Dermatology is a board-certified dermatology practice in Northwest Washington, DC, offering comprehensive medical, surgical, and cosmetic skin care for patients throughout the DMV region. Our team of four specialists covers the full spectrum of dermatology — from acne and eczema to Mohs micrographic surgery and advanced injectable treatments — all under one roof at 4910 Massachusetts Ave NW.
We serve one of the most diverse cities in the country, and our expertise reflects that. Two of our physicians trained at Howard University Hospital, widely recognized for excellence in caring for patients with diverse skin tones and conditions that disproportionately affect skin of color. At FoxHall, inclusive dermatology isn't a marketing line — it's how we were trained and how we practice every day.
Whether you're coming in for a routine skin exam, managing a chronic condition like psoriasis or rosacea, or exploring cosmetic treatments like Botox® or dermal fillers, you'll receive care from physicians and providers who know your skin and take the time to get it right.
Washingtonian Top Doctor: 2022 · 2023 · 2024 · 2025
Dr. Suah is a Washington, DC native who completed his medical training at Howard University, the DC VA Medical Center, and Children's National Hospital. He has been recognized as a Washingtonian Top Doctor four consecutive years — a distinction awarded by peer physician survey, not patient volume.
His clinical focus spans medical and cosmetic dermatology, with particular expertise in caring for patients with diverse skin types. Dr. Suah personally performs all cosmetic injectable treatments at FoxHall, including Botox®, Dysport®, Xeomin®, and Jeuveau®. He also offers general dermatology care for conditions including acne, eczema, hyperpigmentation, melasma, and hair loss.
Dr. Bembry specializes in pediatric dermatology, skin of color, and complex medical skin conditions. She brings a thorough, unhurried approach to every visit — whether she's treating a child's first eczema flare or managing a long-standing inflammatory condition in an adult patient.
Her training and clinical focus make her one of the most sought-after providers in the practice for patients whose skin concerns have been misdiagnosed or undertreated elsewhere. Conditions including keloids, central centrifugal cicatricial alopecia (CCCA), post-inflammatory hyperpigmentation, and scalp disorders are among her areas of expertise.
Dr. Nozile is double board-certified in dermatology and Mohs micrographic surgery — one of the most precise and effective treatments for skin cancer available. Mohs surgery achieves the highest cure rate of any skin cancer treatment while removing the smallest amount of healthy tissue, minimizing scarring and preserving cosmetic outcomes.
Having a fellowship-trained Mohs surgeon on staff means FoxHall patients can receive diagnosis, surgical treatment, and follow-up care within the same practice — without referral to an outside surgical center.
Carolyn brings a warm, patient-first approach to a full range of dermatologic concerns. She provides expert care for acne, eczema, psoriasis, rosacea, and age-related skin changes, and performs cosmetic treatments including Botox® and Dysport®. Patients consistently describe her as thorough, approachable, and genuinely invested in long-term outcomes.
Four Consecutive Years as a Washingtonian Top Doctor Dr. Suah has been named a Washingtonian Top Doctor every year from 2022 through 2025 — one of the few dermatologists in DC to hold this distinction four years running.
Mohs Surgery In-House Dr. Nozile performs Mohs micrographic surgery on-site at our Massachusetts Ave location. Patients with skin cancer diagnoses receive gold-standard surgical care without leaving the practice they already trust.
Specialized Expertise in Skin of Color Washington, DC is a majority-minority city, and skin conditions present differently across skin tones — affecting diagnosis, treatment selection, and outcomes. Our team is specifically trained to recognize and treat dermatologic conditions in patients with darker skin, including hyperpigmentation, melasma, keloids, hair loss disorders, and inflammatory conditions that are frequently mismanaged in general dermatology settings.
Complete Care Across Every Stage of Life From a child's first eczema diagnosis to adult skin cancer screening to cosmetic rejuvenation, FoxHall provides continuous, comprehensive dermatology care for patients at every age and stage.
Convenient Northwest DC Location We're located at 4910 Massachusetts Ave NW, Suite 308, easily accessible from Georgetown, Foxhall Village, Palisades, Glover Park, Tenleytown, Friendship Heights, and the broader DC, Maryland, and Virginia area.

Dr. Matzie was born and raised in Granby, Connecticut. She decided to pursue a career in medicine after undergoing an operation in her freshman year of college.

Elizabeth Alexandra Zubowicz, MD, FACS, FASMBS is a board-certified general surgeon. She specializes in bariatric surgery and hernia surgery. She performs both open as well as minimally invasive surgery, with a focus on robotic surgery and its advancement in the realm of general surgery. She has performed over 1000 bariatric procedures and has a passion for helping patients get healthier.
One of the biggest concerns post bariatric surgery is “loose skin.” After so much hard work and effort to lose weight and get healthier, patients still have this loose skin that can significantly impact their quality of life and self-image. Skin removal surgery is rarely covered by insurance and can be an extremely long and painful recovery.
In addition, being a mother of 2, she personally felt the body image challenges of having permanent loose/sagging abdominal skin no matter how many crunches after having babies. After extensive research, Dr. Zubowicz was impressed by the significant results from minimally laser techniques for loose/wrinkled skin and decided to incorporate it into her practice.
This market-leading body-contouring technology can be used on many areas of the body and can help improve skin laxity after weight loss, pregnancy or aging. It is also great for removing those last stubborn areas of fat that just can’t be lost no matter how much weight one loses.
She is extremely excited to now offer these skin tightening and rejuvenating techniques as well as other minimally invasive approaches to graceful aging and improved overall body wellness at Thrive Medspa.
Dr. E. Alexandra Zubowicz is a board-certified general surgeon and a Fellow of the American Society for Metabolic and Bariatric Surgery as well as the American College of Surgeons. Dr. Zubowicz received her medical degree from University of Texas Health Science Center San Antonio. She completed her residency at the Georgetown-Medstar General Surgery Residency Program in Washington, DC. She has presented at numerous regional and national conferences and has been published in multiple peer-reviewed publications.
Dr. Zubowicz is originally from Atlanta, Georgia. She has an interest in medical mission work and has been on several medical mission trips, in both Ecuador and in the Philippines. Her husband is active duty with the United States Army, and they have two daughters Gabrielle and Sophia.
