LESLIE WILLIAMS
GENERAL MANAGER

Our General Manager, Leslie Williams, is originally from Chattanooga, TN. She joined Galleria BMW for its grand opening in May of 2017! She has worked for the BMW brand for 20 fun and exciting years, and she says, “I found my passion with BMW, the last remaining wholistic, family-owned automotive company in the world. I believe the combination of performance and luxury a BMW provides is truly unique, but owning a BMW is more than driving and experiencing The Ultimate Driving Machine. It is inspiring to work with associates who genuinely care about your experience, purchase, and service after the sale.” Leslie’s inspiration comes from growing people around her and from her family. When she isn’t at work, she is spending time with her husband and four children.
