Meet Our Team

Dr. Mattson

My dental school and orthodontic training are from the University of Pennsylvania as I grew up in Philadelphia. I now realize how lucky I was being exposed in my young years to the tremendous faculty at Penn at that time. I am humbled to realize that many of my treatment decisions stem back to what these great teachers exposed me to. “We stand on the shoulders of giants”.

Beside my career in private practice in Olney, Maryland, I have been on the faculty of the University of Pennsylvania serving as Clinic Director and the faculty of the University of Maryland serving as Associate Clinical Professor in Orthodontics. My teaching responsibilities included biomechanics and diagnosis and treatment planning with the orthodontic resident while guiding them with patient care. I also was the orthodontic staff member for the Department of Craniofacial Anomalies at Children’s Hospital in Philadelphia and Washington DC.

I am a life time member of the American Association of Orthodontist, American Dental Association, Maryland State Dental Association and the Middle Atlantic Orthodontic Society.

Dr. Dalia Shlash

Dr. Dalia Shlash grew up in Gaithersburg, Maryland and later attended the University of Virginia in Charlottesville, Virginia.  She received her Doctor of Dental Surgery (DDS) degree from the University of Maryland School of Dentistry in Baltimore, MD where she received the Harry E. Kelsey Orthodontic Award and was a member of the Ferdinand Gorgas Odonatological Honors Society.

Dr. Shlash went on to further her dental training by completing the Advanced Education in General Dentistry residency at the University of Maryland School of Dentistry.  While she was a resident, she also obtained a Master in Public Health degree, as she is interested in improving public policy for dental and orthodontic health.  She completed her orthodontic residency at the University of Maryland School of Dentistry, which is where she met Dr. Mattson, her all-time favorite clinical instructor.   She is honored to be working along side Dr. Mattson in the months to come and looks forward to carrying on his legacy of compassionate, high-quality orthodontics that he has established in Olney for over thirty years. 

Since dental school, Dr. Shlash worked in a cutting-edge Diamond+ Invisalign orthodontic practice with locations in Howard, Baltimore, and Carroll counties for many years and is happy to finally establish herself in her native Montgomery County.  She resides in Howard County with her husband and three kids and enjoys spending time with her family and going on hikes on the various local trails and county parks.   


Natalie joined our team in September, 2018 as our full time front desk receptionist. She is always smiling (and what a great smile she has!) and willing to help in any way she can. In her spare time she enjoys hiking, making crafts, eating spicy foods and spending time with family. We are fortunate ans happy to have Natalie working in our office.


Diane recently switched from full to part time as our bookkeeper. She keeps us afloat with all the business needs of the office.


Donna first worked on our team as a certified chairside assistant right out of high school. Her artistic talent and energy led her to college. There after she married and welcomed three children. Fortunately when the children grew older she returned to orthodontics with us. A lucky day for me. She has managed for two decades all our treatment implementation needs while helping me as a certified chairside assistant. Could not run this office without her.


When Esmeralda joined us she raised the intellectual level of our team by being bilingual. Her biggest frustration is in trying to teach me Spanish but she is a treasure for our Spanish speaking patients. How do I know? Because she doesn’t stop talking in Spanish if that is your primary language! She is a certified orthodontic assistant working with me in adjusting the treatment appliances.


She is a very important part of our staff since her main responsibility is making ready the instruments needed to work. We therefore can move efficiently, staying on schedule so you do not have to wait beyond your appointment time.

Karleigh’s  life is occupied with training event horses and she competes as a member of the USA Young Riders Team. Go Karleigh!

We are grateful to have her assistance in delivering quality care to our patients and look to a bright future as she moves on in life.
