Megan Speirs, DDS

Dr. Megan Speirs was born and raised right here in Amarillo, TX. She graduated from Amarillo High School in 2012 as Salutatorian and attended Brigham Young University in Provo, Utah, where she graduated with a BS in Exercise Science in 2017. She then went on to attend dental school at the University of Utah in Salt Lake City, while serving in a 2-year position as president elect, and then as president of the Utah chapter of the American Student Dental Association. Megan's time and efforts have always been dedicated to serving others, which is why it was relatively easy for her to choose dentistry as a profession while in college. She not only considers dentistry an honor, but a calling. During her time serving as ASDA (American Student Dental Association) President, she not only worked closely with the Utah Dental Association to plan annual conventions, but served on the committee for the annual charity event, Give Kids A Smile, to bring together hundreds of community dental professionals who volunteer their time to provide free dental care fo children in the Salt Lake Valley.

During Dr. Speirs' third year of dental school she had a baby, which led to her helping draft and implement a family-leave policy at the University of Utah School of Dentistry. She more recently has used her passion for organized dentistry, and gone on to become a member of the ADA (American Dental Association) and was a recipient of the International College of Dentist's Humanitarian Award for ""exemplifying and demonstrating passion for altruistic humanitarian service as a dental student"" in 2021. She has always believed that excellent dental care should be available to everyone, which has helped her in saying ""Yes"" to the many God-given experiences and people that have been placed in her path, including serving in the mission field from 2013-2015 where she learned Spanish while serving with The Church of Jesus Christ of Latter-day Saints.

In her personal time, Dr. Speirs is a dedicated wife to her loving husband, Colby, and a wonderful mother to their baby girl, Rowan. Together, they're a family of faith, and are dedicated members of their church. Over the years she's enjoyed playing violin, having played in the Symphony Orchestra at BYU, and has largely enjoyed doing gymnastics at Amarillo College, after which, she was able to coach a team in Salt Lake as an undergrad student. Her down time now mainly includes running, reading, and hiking, preferably at her favorite spot, Grand Teton National Park.

Shemen Dental Group

of Amarillo, Texas

After brothers, Dr. Eddy and Dr. Scott Sauer combined their dental practices into one business, they were stumped as to what to name their newly combined practice. As Dr. Eddy was studying his bible, reading in the Psalms, he came across the word that suddenly got his attention, “oil,” a word that was used for anointing and healing. The word translated in Hebrew is “Shemen” – which the brothers immediately knew should be the name of their practice, as it perfectly described the goal of their practice, to be a place of healing for all of their patients. They have been in the business of practicing their namesake, “healing,” ever since.

Dr. Scott has since moved to Frisco with his family and continues to practice dentistry with another dental practice.

Now led by Dr. Eddy Sauer, Jr. and Dr. Nathaniel Avirett in Amarillo, TX, our team at Shemen Dental Group LLP offers modern dental services with a focus on personalized care.
