I strive to make every patient feel at ease and do whatever it takes to make your visit a fabulous one. My goal is not only make each visit go smoothly, but also make each patient feel at ease and build a lasting relationship. I have been happily married to my husband for 5 years.

Hi, I'm Mary Anne, one of Fenton Family Dentistry's Registered Dental Hygienists and Mother of two. I grew up in St Louis and am the youngest of seven kids.
