Dr. Austin Erker 

Dr. Erker

Dr. Austin Erker is very excited to be joining Smith Chiropractic.  He was raised and grew up in Ballwin, Missouri. Throughout his childhood he was very active playing sports such as baseball, soccer, roller hockey, and golf.  He attended high school at nearby Marquette High School in Chesterfield, Missouri. It was there, where he took a liking to human anatomy and biology sciences classes. He was also very active in golf and played the saxophone in the marching band.  After graduating, he went on to attend The University of Missouri in Columbia. He continued his love for the sciences by graduating with a Bachelors of Health Sciences.  

Dr. Austin became aware of the vast benefits to chiropractic care when his mother received treatment for neck pain and migraine headaches.  Throughout care he saw his mother’s neck pain improve tremendously, and she was able to stop taking her migraine pills. It was then when he decided to continue his education at Logan University for a degree in Chiropractic. While in school, he specialized in treatments such as Diversified, Cox Flexion-Distraction, and Active Release Technique.  He continued his education after graduation by certifying in MPI and Selective Functional Movement Assessment (SFMA).  

While he believes that everyone can benefit from chiropractic care, he has a passion for treating athletes and active patients alike.  He believes that chiropractic adjustments along with myofascial release and rehab exercises combine to be the best conservative treatment for his patients.  

Dr. Austin continues to be an avid golfer.  He also spends most of his free time working out, traveling, spending time with family and friends, and rooting on the St. Louis Cardinals, St. Louis Blues and Mizzou sports.  Dr. Austin looks forward to treating you and your family and friends. It is time to take your health seriously and live the best possible life that we were meant to live all along.  Take charge and see you soon!

Hi, my name is Brooke. I was raised in Ballwin, Missouri and still reside there with my husband Eric and two boys, Evan and Andy. I suffered from severe lower back pain and became a patient in early 2016. I was delighted with my results and really enjoyed the difference in philosophy. Several months later I became an employee, excited to share my love of chiropractic with others. After successfully managing my symptoms through adjustments and the decompression table, I now maintain my spine with weekly adjustments.

Since starting at Smith Chiropractic in 2016, I have seen miracles occur before my eyes. Whether it is a baby being adjusted for the first time or a grown adult walking out of the office feeling like a million bucks, there is never a dull moment in the office. I love that my passion for this job continues to grow. There is never a day that goes by that I am not learning something new, making a new friend, or working as a team. I am incredibly grateful for where I am in my life and could never thank Smith Chiropractic enough.

When I am not at the office, I like to do just about anything. On weekends, my husband and I are going to the lake with family, camping, cooking, gardening, or spending quality time with our family and friends. My goal is to make sure you leave the office with a smile on your face.


Hi, my name is Anna and I’ve been working with Smith Chiropractic since 2001. Over the years, my love and passion has grown immensely for the chiropractic field. Not only do the chiropractors at this office treat the pain and symptoms that patients walk in with, but they treat the patients like they are family. The relationships that we develop with all of our patients are just as important as taking away their pain and discomfort. My goal, everyday, is to make sure that your total experience in our office left a smile on your face and confidence in your heart for resolution of your pain.I was born and raised in South County. Currently I live in Lincoln County with my husband Chris, our two beautiful children Rylee and Ty, and our yellow lab Zoey. When I’m not working, my husband and I are running the kiddos to their sporting events, camping, boating and/or fishing. Personally, as long as I can be in the sunshine—I’m happy!


I am a St. Louis native and grew up with Chiropractic care. It has always been a part of my family's health and lifestyle. We have been seeing Dr. Smith for over 15 years. I was thrilled to receive an opportunity to join this team in 2012. Being a part of this positive group has impacted my life. My passion is getting to know the individual patient and working with them as they return to health.

My husband, Tim, and I have 2 beautiful daughters and 2 Portuguese Water dogs that keep us busy. I enjoy running, cooking and rooting on our St. Louis Cardinals!


I am originally from the Cleveland, Ohio area and moved here about 10 years ago with my husband and children.  I have been a patient of Dr. Smith’s, and had the privilege of knowing Dr. Smith through our sons’ baseball careers.  Over the years, Dr. Smith has treated our entire family with care and personal attention.  I started working for Smith Chiropractic in June 2019, and although it’s a big switch from homeschooling my six children, I love my new spot in life and especially the wonderful people, (doctors and patients), that make Smith Chiropractic the uniquely professional and yet personal place that it is. My hope is that I can help our patients feel deeply taken care of as they seek treatment for their health issues. 

Some of my favorite things are waterskiing, reading, working out, photography, doing life with my kids, and going on dates with my hubby, Rick! 


Hi, My name is Lesa. I started out as a patient and was thrilled to join the staff of Smith Chiropractic in 2018. I love meeting the patients and seeing them achieve their health goals. It is truly a pleasure to work in such a positive environment, surrounded by such caring and talented professionals.

My husband, Steve, and I live in Chesterfield and have two daughters and one very spoiled Shih Tzu. When I'm not working at Smith Chiropractic, I enjoy crafting, hiking, traveling, and spending time with family and friends.
