Jacquline Rivera


With 4 years of experience in the field of dentistry, I am excited to have recently joined Lansdowne Family Dental as a new associate in the New Year 2023. I find great pleasure in interacting with my colleagues and patients, and constantly learning and growing to provide the best service. I am a local from Sterling, VA, a graduate of Potomac Falls High School and a Northern Virginia Community College attendee.

In my free time, I enjoy reading especially mystery, but I am open to nonfiction, realistic fiction and biographies. Additionally, music is one of my passions, and I enjoy listening to a variety of genres, including classical, country, pop and others, while taking walks. I am also fascinated by the world of dreams and have the ability to remember and interact with my dreams while I sleep. It’s like watching a movie where I am fully aware of my actions and words within the dream while being in a deep sleep.
