Mitzie Slayden

Mitzie Slayden, Au.D., CCC-A

Dr. Mitzie Slayden has been an audiologist for thirty years.  She earned her Bachelor of Science in Communication Disorders from Murray State University in 1980.  In 1986, she completed her Masters in Audiology at the University of Memphis.  She later returned to Salus University to obtain her Doctorate in Audiology and completed in 2009.  During her career, she has had the opportunity to work in private practice settings and with hearing aid manufacturers.  As an outside representative with a manufacturer, she worked with audiologists in their offices training them on the latest technology as well as helping ensure successful hearing aid fittings with patients with challenging hearing losses.  She applied this knowledge to helping patients when she began her own private practice.  Over the years, she has helped thousands of hearing impaired people to hear better.  Mitzie believes she is providing her patients with a better quality of life by improving their ability to communicate with their friends and family. 

Mitzie grew up in Gallatin and Clarksville and has lived in Mount Juliet since 2006.  She shares her home with her "fur baby", Honey, a Malti-poo that she has spoiled.  She is an avid reader and enjoys seeing movies, Broadway shows and musicals, and attending live music venues. Traveling to new places whether near or far, flying to a new country for vacation, or a quick road trip on the weekend is her favorite way to spend her free time.
