Meet The Warrington Orthodontics Team

Emily - Dental Assistant

Emily is a dedicated dental assistant atWarrington Orthodontics, where she thrives as part of an incredible team committed to transforming patients' smiles and boosting their confidence. A resident of Warminster, Emily lives with her parents, three brothers, and a collection of pets, including three cats and a dog. She graduated from William Tennett High School and took up dental assisting at Middle Bucks Institute of Technology. Emily aspires to become a dental hygienist.

Emily enjoys the teamwork at Dr. Markham and Dr. Foley's practice, which she believes creates the best care experience for their patients. In her free time, Emily loves hanging out with her friends and family, as well as watching movies from the Marvel and Fast & Furious franchises.

Gillon - Dental Assistant

Gillon is a skilled dental assistant who has been with the practice for over eight years. With a passion for hands-on work, Gillon enjoys both the people she works with and the patients she serves. She is originally from Abington and currently resides in Willow Grove.

When she isn't at work, Gillon enjoys spending time with his family and friends, shopping, and reading. A fun fact about Gillon is that her father, a self-proclaimed mediocre poker player, regularly loses to Rick Markham, much to the family's amusement.

Cindy – Receptionist

Cindy, the friendly receptionist at Dr. Markham and Dr. Foley’s office, is a lifelong Warminster resident. She has over a decade of experience working in orthodontics, including a 12-year stint at another office. Recently, Cindy volunteered at the elementary school her sons attended, a role that allowed her to interact with children — something she loves to do. Now, she continues to enjoy seeing the bright, happy faces of young patients at Warrington Orthodontics.

Cindy values the kindness and friendliness of the team she works with. Outside of work, Cindy is a proud mother of three boys (and one "grown-up" son in her husband). She also enjoys walking, reading, and spending Friday nights playing games with her family.

Julissa - Dental Assistant

Hi. I am a dental assistant with Dr. Markham and Dr. Foley. I work on our patients, sterilize instruments, stock supplies, and handle anything else that is needed.

My family is originally from El Salvador, but we have lived in Warminster for 14 years. I am the oldest of five children. I have three brothers and one sister. I attended William Tennett High School and the Middle Bucks Institute of Technology’s dental assisting program.

When I am not working, I like to go to the gym, play soccer, and just hang out with my friends and family.

I love being part of a dental team and seeing smiles change. Everyone at Warrington Orthodontics is supportive, and Drs. Markham & Foley are amazing doctors. I learn so much from them.
