Why Choose Our Practice?

Dr Callahan talking to a patientBlending art, science, and technology, Dr. Cheryl Callahan, Dr. Kate Nematollahi and our talented team strive every day to give our patients a beautiful smile. Our practice is devoted to providing you with extraordinary service and the highest quality of care at every visit.

We concentrate on your personal comfort: developing open lines of communication and creating personal treatment plans to help you attain and maintain optimal oral health and a beautiful smile.


Developing Lasting Relationships: We treat all our patients as we would treat our family — with respect, compassion, and genuine care for their well-being. We take the time to learn about each patient, listen to their concerns and fears, treat them as an important individual, and customize their care to meet their needs.

Education-Based Decision Making: Educating our patients to improve their health and quality of life is our focus. We understand the vital connections between the oral health and overall body health, and teach our patients about how these two are closely intertwined.

Comfort-Based Treatment: Our patients’ comfort is our highest priority, and our treatments and technology reflect that. Digital X-rays and iTero® digital impressions make diagnostics easier and more accurate, while our soft-tissue laser and nitrous oxide (laughing gas) make treatment faster and more comfortable.

Advanced Care for Your Smile: We go beyond general dentistry to offer advanced care to make you smile. Our in-office CEREC® machine produces custom crowns during a single office visit. For those with sleep apnea and snoring issues, custom-made sleep appliances can give you the restful night’s sleep you desire. And, to improve the appearance of your smile, we offer a full line of Invisalign® clear orthodontic aligners.


We offer complimentary consultations at our Rockville, MD dental office, where we welcome patients throughout Montgomery County and the Washington DC area. Please call to schedule a consultation!
