Scanning Technician

I am a recent graduate of UMBC, where I studied Biology. I decided to take some time off from school to start working.

I am so grateful for the opportunity to be working in an environment where I am constantly learning an abundance of information about the field of orthodontics. I love being challenged to always provide top notch care and the ability to work with the latest technology. I am honored to be a part of the OX team. It is a pleasure to work with both the staff and the patients.

New Patient Coordinator/Marketing Assistant

Christine joined OXOrthodontix in March 2014. She previously worked with Drs. Hickory and Selnick and is very happy to be back working along side them again creating beautiful smiles. She has 27 years of experience in all aspects of the orthodontic field including orthodontic assisting, treatment coordination, office management and marketing. Christine and her husband Tom enjoy watching their daughter Marissa play lacrosse and are so proud of her recent college graduation from Stevenson University. Christine enjoys yoga, the beach and dinner and wine with good friends.


Administrative Assistant

Having worked at OX since April 2011, I enjoy the field of orthodontics. It is a pleasure to work for such talented doctors, and I admire their way of making our patients happy. I am a native of Bulgaria and I currently live in Ellicott City, MD. I have two adorable children, Iva and Nicholas. In my free time, I enjoy spending time with my children, taking them to the parks, and playing with them.



Front Desk Coordinator

I have worked here since February 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 live in Carroll County, and in my free time, I enjoy spending time with friends, traveling, and watching movies.


Business & HR Administrator

I joined the OX team in December of 2013. What's not to love about OX Orthodontix? I get to work with top docs who use the most cutting edge technology to give every patient the smile they have always wanted. Favorite thing to do in my free time is spending time with my awesome family and friends.



Clinical Technician

I am a clinical technician and I have been with the OX team for 1 year. I enjoy working here because of my interactions with the patients. I am here to give patients great customer service and quality efficient work and that is what I do! I take my job seriously but I don't take myself too seriously that's why my patients always leave with a smile!


Orthodontic Technician

I've been a part of the OX team since 2010. I like learning about new advancements and technology as they occur in orthodontics. I am a southern girl at heart, but currently reside in Gaithersburg, MD with my husband and two-year-old daughter, Julianna. Together, we love to go to the park, shop (more like look!), and bake scrumptious desserts for everyone at OX.


New Patient Coordinator

I like working at OX because every day I get to meet different residents of the communities where our offices are located. I get to know about the patients and/or parents and their hobbies. When they come through the door, I know they've been referred to our office by word of mouth or referral from their primary dentist, and I find joy in knowing that we are setting them up for success in obtaining a beautiful smile! When not working, I love going to the beach, and hanging out with my friends and fiancé. I like to shop, especially for my niece and nephew! Also, I have family that lives in Italy, and it's always fun to Skype with them!


Orthodontic Technician

I have known Drs. Hickory and Selnick for 12 years. I enjoy working at OX because the doctors are fabulous! In my spare time, I spend every minute with my son who is 12. He is the moon and the stars of my life. I also enjoy taking walks with my "crazy dog". In addition, I enjoy cooking Persian food for my husband.


Executive Assistant

As the Executive Assistant at OX Orthodontix, I've worked with our fabulous doctors since 2003 and seem to learn something new from them every day. Coming to work for Drs. Hickory and Selnick has been the best decision I have made. I've learned about Invisalign, all types of digital technologies and I love working with hip and up to date doctors. When I'm not working, I'm home enjoying time with my husband, kids and 2 dogs. I have 3 daughters- 7 years old, 4 years old and a newborn. They keep my life active to say the least. I look forward to meeting you when you visit the office.
