About Our Capitol Hill Dental Practice


Dr. Nishan Halim arrived in July, 2013 to carry on the practice started in 1976 by retiring Dr. Jeffrey Stallsmith. Four years later, the practice of Nishan Halim, DMD has become an important part of the Capitol Hill community in its own right. The practice has won three notable awards thanks to votes by enthusiastic and loyal patients.

Nishan Halim, DMD, specializes in adult and pediatric restorative and cosmetic dentistry, as well as preventative dentistry, which is at the heart of this general and family dental care practice. Enjoy the website and we look forward to welcoming you into the family as a new or returning patient!


Alicia (Halim) joined the practice in 2015, with a strong background in dental assisting and practice management, from previous jobs. Alicia served as Team Leader in the early years, and has, more recently, played an important behind-the-scenes role in managing patient data, as she and Dr. Halim have been about the business of starting and growing a family.

Having recently returned from family leave following the birth of Dr. Halim’s and her third child in June 2020, Alicia stands ready to assist patients with financial questions and resolutions. 


Marilyn has enjoyed the diversity of living in DC all of her life. Helping people and keeping up with advances in technology – especially as they relate to the field of dentistry and patient care – are two of her most important values. When Marilyn isn’t at work, she may be found in her NW DC neighborhood, providing pet care to community members that need a helping hand. She loves animals as well as people and it means a lot to her to spread joy, love, and compassion in the world. We’re glad she is here and hope you will welcome her, too!



Dr. Halim’s reputation and popularity have been growing since he set up practice in the bustling Capitol Hill neighborhood of Washington DC.  Singles, couples, children… all are welcome and cared for like family.
