Holly Walsh

Dental Hygienist

A North Carolina native, Holly Walsh has enjoyed working as a dental hygienist for more than
18 years. She believes that a healthy smile is an important part of overall health and enjoys
building meaningful connections with her patients while helping them achieve and maintain
healthy smiles.


“I love working as a dental hygienist because it gives me the opportunity to connect with
people and contribute to a healthier community.”


Outside the office, Holly enjoys spending time with her husband and daughter, hiking, and
crafting. She is also an animal lover and shares her home with what she proudly calls the
world’s cutest cats, Miso and Chow Mein. Holly is a member of the Surfrider Foundation, an

Alexandra Maria

Dental Hygienist

Born in Arlington and raised throughout Northern Virginia, Alexandra “Ally” Mari is a Dental
Hygienist who is proud to care for patients in the community she calls home. She graduated
from Old Dominion University’s School of Dental Hygiene in 2021.


Ally approaches dental hygiene with empathy, understanding, and a strong emphasis on patient
education. She especially enjoys helping patients who may not have received the guidance or
education they needed to develop healthy oral hygiene habits. Rather than focusing on the
past, Ally believes every patient deserves the opportunity for a fresh start.


She enjoys giving patients that “reset” by working alongside them to develop better habits,
improve their oral health, and feel more confident caring for their smile at home. Her goal is to
make each visit encouraging, educational, and free of judgment.


As she likes to say, “It’s a beautiful day to save smiles!”


Outside the office, Ally loves traveling and hopes to visit every continent. She also enjoys
attending concerts with family and friends and staying active with her Zumba community.
