Meet the San Marcos Dental Team

Marilyn Fox, Insurance Coordinator

Marilyn handles several important tasks in our San Marcos dental office, including scheduling procedures for patients, reviewing their treatment plans, and organizing important insurance information. She is proud to have been working in this position for 11 years now and brings a detail-driven, organizational approach to Rio Vista Dental. These characteristics allow her to provide accurate results for her patients!

Like the doctor, Marilyn is also happily married to her high school sweetheart, and they have two daughters, a son-in-law, and a growing grandson. When she’s out of the office, she enjoys traveling, going to concerts, and indulging her guilty pleasure – science fiction.

Aubrey Barnhart, Registered Dental Assistant

Aubrey works closely with Dr. Earnest to provide quality chairside care, as well as digital X-ray assistance. She has been with our practice for many years and loves being able to help patients improve their oral health. She really enjoys the respectful, quality approach at Rio Vista Dental!

In her free time, Aubrey loves being with her son, attending rock concerts, baking, disproving the existence of dinosaurs, and running 5Ks alongside Lisa.

Kim Johnson, Hygienist

Kim has a knack for dental cleanings that are both thorough and gentle, and she makes sure to pay plenty of attention to patients’ comfort levels. She’s been practicing dental hygiene here in San Marcos for over seven years now and was voted one of the best hygienists in the 2012 Herlad-Zeitung’s “Reader’s Choice Awards.” She is also a member of the National Scholars Honor Society and Phi Theta Kappa. For Kim, it’s not important to judge or lecture her patients about their oral hygiene routines – instead, she wants to help you find the perfect plan of action that keeps your smile shining. Our patients really enjoy her positive attitude and kind honesty!

Kim has been happily married to the love of her life for 30 years now. When she has free time, she enjoys having fun game nights with the whole family, decorating, doing DIY projects, working in years, and cuddling with her husband while they watch the latest shows on Netflix.

Joanna Lehrmann, Hygienist

Joanna makes it a point to stay up-to-date with the latest advancements in dental care so that she can keep your smile healthier and happier over the years. She has a degree in horticulture from Texas Tech, as well as a degree in dental hygiene from Amarillo College. She provided dental care to people in need during a mission trip to Nicaragua in 2011, and today, she’s a proud member of the American Dental Hygiene Association. She enjoys being able to have fun with her patients and show them how much she cares about their oral health.

Joanna has lots of family all over Texas, and she loves spending time with them whenever she gets the chance. During her free time, she enjoys keeping up with the Texas Tech Red Raiders, being outdoors, and kayaking.
