Bridget McCool, RDH
Lead Hygienist

Bridget most commonly provides the first and most fabulous impression at Noble Dentistry. Our new patients are pleasantly surprised by her thoroughness, often remarking “I’ve never had my teeth cleaned like that!”; and returning patients look forward to their next visit. It is abundantly clear that Bridget takes tremendous pride in her job and takes extreme care with each patient. She is highly detail oriented, very knowledgeable and forthright with education & home care. Bridget sets the bar high for all of our hygiene staff… and not just clinically – Bridget is well known for her vibrant and always matching attire! Sneakers, watchband and scrubs included 🙂 Fun fact: Bridget has always wanted to learn how to crochet, so if you know, teach her!

Kate Kelly
Hygienist, RDH

Kate was one of the first employees at Noble Dentistry shortly after the practice’s inception. Before starting as a Dental Hygienist in December of 2017, Kate graduated from Montgomery County Community College in 2015 where she won the Johnson & Johnson Special Needs Award. Kate says she loves coming to work each day because of her ability to help educate patients about their oral health while being in a comfortable environment, which she believes sets Noble aside from other dentists’ offices. In her free time, Kate loves to cook when she is not spending time with family and friends.
