Office Administrator

Our patients are my favorite part of my job. They come to us because they know we provide the best care. They’re smiling and thanking us when they leave because we’ve exceeded their expectations. Each of them is fascinating, and I love getting to know them and their families. At our practice, I make sure everything runs smoothly so our team can focus on providing a seamless, wonderful experience for each patient. I oversee our team by coordinating all aspects of staff relations, plan staff meetings and continuing education classes, schedule staff, and provide training to new employees. I am responsible for all communication with vendors, I track, order supplies, and meet with vendors to review new products. I also provide assistance in the clinical area as I am an expanded functions certified dental assistant and also a dental radiation technologist. I keep very busy, but I’m never too busy to answer questions.

Outside the office, I spend my free time with my husband Orlando, our son Orlando Daniel, our daughter Sofia, and our Mini Pinscher, Max. My husband and I love to cook together and we also enjoying spending time outdoors with our children.



Dental Hygienist

The most important part of my job is providing excellent dental care to our patients. I love to teach them how to maintain a healthy mouth and how this relates to the health of their entire body. I also like getting to know them personally, because they become like family members, and I can’t wait to see them at their next visit so I can hear about all the events in their lives. I provide dental hygiene care and periodontal care. This includes cleaning, debridement, non-surgical periodontal treatment called scaling and root planning, and periodontal maintenance. In addition I perform an oral examination assessing the mouth for disease. I provide education to our patients on dental treatment that may improve their health or esthetics. Together the patient and I create an at home treatment plan to improve and maintain optimal oral health.

I hold a Bachelors of Dental Hygiene from the University of Maryland School of Dentistry in Baltimore, Maryland. I am certified to deliver local anesthesia, in addition to nutrition counseling and smoking cessation. I attend many lectures and workshops that allow me to stay on top of the latest technologies in dental hygiene. 

My husband Dan and I have three children, two girls and one boy. In my free time, I love to swim, bake, and dance, and teach Vietnamese at my church. I am an active member of the American Dental Hygienists Association, and the Montgomery County Dental Hygienists Association. 




Dental Assistant 

I love the chats I have with our patients, to catch up on the news about what’s been happening in their lives and their families, or learning about the interests of someone who’s new to our office. These conversations are interesting and I learn a lot. I spend individual time with each patient during their visit explaining the procedures we will be performing, answering any questions and attending to their needs. I assist Dr. Callahan provide excellent dental care, in addition I take digital X-rays, impressions, and perform any necessary lab work. I always focus on the patient—assuring they are comfortable and relaxed. I am also responsible for sterilization of instruments, OSHA monitoring and all coordination with the outside laboratories. 

I’m happily married to Vincent. Together we enjoy spending time with our daughter Vivian, and our family. We also enjoy hanging out with friends, shopping, and going to the movies.
