  • Jennie Alexander
    DC
    Chiropractor

    Dr. Alexander was born and raised in the Gallatin area. She attended Tennessee Technological University graduating in 2010 with a Bachelor’s in Science majoring in Agriculture. She returned home to work with her family in the family business, Alexander, and Family Heritage Funeral Home. After being in the business for 5 years, she realized she was on the wrong end of the spectrum. Instead of trying to help families with the loss of their loved ones she wanted to help families have more memories together. Loving anatomy and physiology and wanting to help people, she remembered working her first job at Gallatin Chiropractic. Reflecting on how much Dr. Groff’s patients and family loved him and the office, she took a leap of faith and applied to Chiropractic College. Being the 5th generation of Alexander’s to work in the funeral home, it was a hard decision to leave but she felt it was right.  She attended Life University where she graduated Cum Laude in June 2018. She worked in Alabama for a year before returning to where it all started, at Gallatin Chiropractic Clinic. 


    During her schooling at Life University, Dr. Alexander took several mission trips which included Africa and Mexico City. She was selected as a University representative to attend The Rubicon, a worldwide chiropractic school conference in Switzerland. She lead the campus MLS club for 2 years and served on Student council for 2 years. She was honored in receiving the Light of Life award for having double the required adjustments and outstanding preforming in her clinicals.  To merge her love of animals and chiropractic she achieved her certification in Animal Chiropractic thru Parker University. This has come in handy as she has a dachshund named Gordon who has lost the use of his back legs and is now adjusted regularly.


    During her time outside of the office Dr. Alexander enjoys working out and eating good food. She attends Long Hollow Baptist Church. She loves to travel, and enjoys crocheting blankets and stuffed animals.


    Chiropractic is dear to her heart as are her patients, and she is extremely excited to be back serving in her home community.
