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 will likely be the first person you see when you walk through the door. Her warmth and smile can put even the most dental-phobic person at ease. As the Team Leader, Alicia supervises the other administrative staff and sometimes helps out chairside, too.

At the moment, Alicia is on family leave following the birth of Dr. Halim’s and her first child in April 2016. While she is away, the front desk and all your patient information needs are in Ashley’s capable hands.


Katina has been a practicing dental assistant since 1998 and loves her work. A native of the Washington, DC area, Katina will tell you that her favorite thing about dental assisting is that she gets to play an active role in helping change people’s lives.  The patients she serves will tell you that she is “sweet, friendly, and thoughtful.” We agree. When Katina isn’t working she enjoys spending time with family – a husband, four children, and one grandson. Katina joined the practice team in 2016. We are glad she is here and think you will be, too!
