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!


Keshia started as a Dental Assistant over 20 years ago and because she loves the dental field, she has worked her way up to Practice Manager. “I love the patient contact.”  Described as compassionate, confident, and encouraging, it seems to be mutual.

A lifelong resident of Prince George’s County, Keshia enjoys Capitol Hill for its sense of community…and the outstanding restaurants!

When Keshia’s not at the office, she enjoys working out and spending time with her 16-year-old daughter and her Bishon-Yorkie, Quincy. She also “loves to laugh!” We like that, too. 


Catrya is the team member that will assist you with your appointment scheduling. This Washington native is no stranger to customer service in the healthcare industry, with 10 years of experience prior to joining this team in 2016. “I enjoy working for a company that provides superior care while maintaining the warmth and hospitality of a small business.” Some of Catrya’s outside interests include art, photography, cycling, coffee and philosophy. Get to know Catrya and she will help to ensure that your visit is seamless and stress-free.


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.
