About Your Doctor

Being up-to-date in the latest orthodontic techniques and treatments for pediatric, adolescent, and adult patients has always been a priority for Dr. Mullen. He is well versed in Invisalign and self-ligating bracket systems that can reduce treatment time and increase patient comfort, and uses the latest technologies in orthodontics to maximize smile aesthetics and give the best possible results to his patients.  He is a diplomate of the American Board of Orthodontics, an achievement earned only by about 25% of practicing orthodontists.

Dr. Mullen grew up in Springfield, Virginia as the oldest of four children. He went to the University of Virginia and earned a Bachelor of Arts in Biology. He then attended the Medical College of Virginia School of Dentistry, where he graduated Magna Cum Laude. While attending MCV, he was a member of Psi Omega dental fraternity and received the Fraternal Achievement award; an award given to the senior student who showed the most outstanding service during their four years of school. Dr. Mullen was also inducted into Omicron Kappa Upsilon, a dental honor society whose members are chosen by the faculty of the dental school. He then completed a three-year orthodontic residency at West Virginia University, and earned a Masters of Science in Orthodontics. 

Dr. Mullen is a member of the American Dental Association, the Virginia Dental Association, the Northern Virginia Dental Association, the American Association of Orthodontists, and is a member of several dental and orthodontic study clubs.  He currently serves as Secretary/Treasurer of the Virginia Association of Orthodontists, and is also represents the SAO as a Delegate to the American Association of Orthodontists.  Living and working in Leesburg with his wife and three young children, Dr. Mullen enjoys hiking, tennis, competing in triathlons, and mountain bike racing.

I have been with the practice for four years and thoroughly enjoy working with all of our patients and their families. I live in Lovettsville with my husband Bruce, our four children and our dog, Diesel. Most days you can find me cheering on one of my kids at a sporting event!

I've been working as an orthodontic assistant for twelve years. What I love the most about my job is being a part of bringing beautiful smiles to all of our patients. I love spending time with my family, learning Italian and photography.

Jessica Hopkins-Orthodontic Assistant

I have been a dental assistant since 1993. I find it very rewarding to be part of a practice that has great patient relationships and helps to give people beautiful smiles. I live in Ashburn with my son, Adam, who is the light of my life. We love to spend time together, especially when I am coaching his soccer team. I also enjoy going to the gym, being outdoors, reading non-fiction, and finding new music.
