She is also bilingual and able to communicate our patients’ needs during their visit. She enjoys the team she works with on a daily basis and seeing how something as simple as a cleaning or a dental filling can make such a difference in someone’s life.

Expanded Duties Dental Assistant

Esra joined us in September 2022. She is an international dentist from Jordan and has passed the American dental board exam. Her favorite part about working at the practice is having the opportunity to continue her education and learn from Dr. H and the privilege to use the latest digital technologies to help expand her experience and proficiency. She contributes to the success of our office with her scientific and educational background and years of clinical experience both in and outside of the U.S.

Esra is married and has three children, Lamees, Layal and Fayez. In her free time, she enjoys hiking, watching movies, traveling and exploring new places.

Laura H.

Registered Dental Hygienist

As a child, Laura enjoyed visits to the dentist. The kindness she received made an impression and inspired her to pursue a career in the dental profession. At 20, she joined the military as a dental specialist, which gave her the opportunity to assist dentists of all specialties. Early on she gained knowledge of different dental disciplines and the importance of interpersonal relationships between health care providers and patients. Later, she became a dental hygienist. This allows Laura to work one-on-one with patients, learn their specific needs, and give outstanding, individualized dental hygiene care.
