Meet the Staff


Office and Mobile Administrator/Dental Assistant

Hello! My name is Vanessa Monterrosa, wife of a very loving husband and mother of 2 amazing children Natalie (8 years) and Jayden (3 years). When I’m not at the office I am spending quality time with my son Jayden. Chasing a 3 year old around is a full time job but it’s worth every moment, he is so loving and everything he does makes my heart melt. My daughter Natalie is a 3rd grader and she enjoys learning, our mommy and daughter time is when I take her to her gymnastics practice, I’m always there cheering her on and letting her know how proud I am of her. I enjoy cooking and spending time with the family, I consider myself a very family orientated person.

I have had the privilege of being part of Dr.Thapar-Dua D.D.S and Senior Smile since August 2011 and I feel like I am part of a family. Dr.Thapar-Dua and the staff are so welcoming and make it easy to fit right in. I enjoy the time that I am working in the office, our patients are so friendly and humble, and they make my job so much better when I see them leave with a big smile on their face and “thank you!.” I look forward to helping our patients and making sure they feel as part of the family as I am.



Dental Assistant/Mobile Coordinator

My name is Agatha Campos, I have a beautiful energetic two yr old son who loves to keep me on my toes. I recently joined Dr.Thapar-Dua and Senior Smile. I truly believe in her mission as a dentist and am quickly learning the ropes. In my spare time, I like to read, cook, and take my son on any adventures that we can find. I grew up in Arlington, VA but have traveled throughout the DMV area as I’ve gotten older. I’m glad that I have this opportunity to help the elderly along side taking care of my parents. Working with Senior Smile has helped me gain a new perspective and appreciation for the elderly, that which I’m proud of.

Since working with Dr.Thapar-Dua I’ve been able to see the other side of dentistry that not many people have had the pleasure of exploring. We work diligently to make sure our patients feel like members of our family and get overjoyed when patients have a wonderful experience. I’m humbled to be a part of such an amazing team of women.
