Top Invisalign Provider Since 1997
Dr. Mitra Derakhshan
Dr. Mitra Derakhshan has worked with Invisalign for over 10 years and has demonstrated her expertise with the clear aligner system by being published in the Journal of Clinical Orthodontics, giving seminars in orthodontics, and lecturing on orthodontic topics worldwide.
Before Dr. Derakhshan joined the OX Orthodontix team, she received her dental degree (DDS) at the University of Michigan and her master’s degree (MS) and Certificate in Orthodontics at the University of Illinois at Chicago.
Outside of the office, Dr. Derakhshan enjoys spending time with her family, traveling, exploring the outdoors, and watching a romantic comedy movie every once in a while.
Dr. Sandra Selnick
Dr. Sandra Selnick is dedicated to staying on the cutting edge of innovative orthodontic treatment to provide the best possible treatment results for her patients. Dr. Selnick takes pride in “creating beautiful smiles for all ages” using the latest advancements in orthodontic technology.
As the daughter of a pediatric dentist and a pediatrician, Dr. Selnick was bound to work as a medical professional too! She graduated with a Bachelor of Science (BS) from the University of Miami before earning her doctoral degree in dentistry (DDS) from the University of Maryland where she graduated with special recognition from the American Association of Orthodontists. After completing a hospital-based General Practice Residency with the VA Medical Center in Baltimore, Dr. Selnick’s interest in orthodontics led her back to the University of Maryland for three years of specialty training resulting in a Certificate in Orthodontics. She concurrently pursued her research in orthodontic computer analysis, earning a Master of Science Degree (MS) in Oral Biology.
In previous positions, Dr. Selnick was in private practice and worked as a staff orthodontist at Children’s Hospital at Washington Hospital Center. She is leader and innovator using Invisalign to treat patients since its introduction in 1997.
Dr. Selnick is also dedicated to giving back to her community and her strong ties in the Howard County area are a source of pride in her professional and private life. When she is not in the office, Dr. Selnick is active with her son, who is a swimmer attending the Naval Academy and her daughter, enjoying her college experience at University of Maryland.
Dr. Kathleen McKeon
Dr. Kathleen McKeon has been excited about orthodontics since she was a young girl growing up in Catonsville, MD. It has been her lifelong dream to be able to share that passion and to make happier and healthier smiles in her hometown. Dr. McKeon graduated with a Bachelor of Science degree (BS) from the University of South Carolina before returning to Baltimore and earning her doctoral degree in dentistry (DDS) from the University of Maryland. While in dental school she was recognized by the American Association of Orthodontists and was inducted into the Omicron Kappa Upsilon Honor Society. Her interest in orthodontics then led her to the University of Pittsburgh where she received a Certificate in Orthodontics and a Master of Dental Science degree (MDS) after three years of specialty training. In her free time, Dr. McKeon is a certified yoga instructor that enjoys spending time with friends and family (including her two cats!), staying active, and enjoying good food and wine. Dr. McKeon is excited to be back home again, to serve the community she grew up in, and to be a part of the OX Orthodontix team!
I have been with OX Orthdontix since 2011. I enjoy learning about orthodontics and the new technology the office embraces, which is amazing. I look forward to seeing everyone with their beautiful smiles! I am originally from Carroll County and now reside in Howard County. In my free time I enjoy to travel, shop, and watch movies.
Malinda grew up in Centreville MD, a very small town on the Eastern Shore.
She said, “I like working at OX because I enjoy meeting new people, and love helping others achieve their beautiful smile.”
A little-known fact about Malinda; she traveled to Italy to play softball and represent the USA.
Candace has over 13 years of experience in the dental field starting as an assistant and working in all other aspects of the dental field as well. The knowledge she has gained through the years and the experience she has, makes it possible for her as a treatment coordinator to help patients gain more confidence that they will achieve the beautiful smile they envision.
When she is not at work you may find her at one of her son’s sporting events, boating, camping or even riding on the back of her husband’s motorcycle! She also enjoys traveling with friends and family.
“I am excited to be part of a team that embraces new technology and empowers me to create a personalized plan tailored to the patient’s preferences and pocketbook,” Candace said.
