Holly — Dental Hygienist

Holly’s energetic, enthusiastic personality is a wonderful addition to our practice.

Holly says, “As the saying goes, ‘I wasn’t born in Texas, but I got here as fast as I could!'”
Holly is originally from southern Idaho.  She and her husband, Tom, moved down to Texas after graduating from college in 2005, and they have been loving the warm weather ever since.

She has a deep passion for dental hygiene, but when she’s not “nerding out” on dentistry she enjoys yoga, reading, hanging out with friends and family, visiting breweries and wineries, puzzles and movie marathons.
