Mimi Whittingslow

Clinic Coordinator and Assistant

Mimi has been with us since the first day we opened back in April 2010. Her favorite part about working at West Cobb Orthodontics is interacting with patients and seeing them light up when they see their beautiful new smile without braces. She is also fascinated by the science of how teeth move and enjoys watching them change over time.

With an impressive educational background, Mimi has attended classes for orthodontic assisting, X-rays, OSHA, and Invisalign® treatment. She is CPR certified and has also completed CE courses from AOA and AAO trade shows.

Mimi works very hard for our patients and the team and makes sure everyone is happy and satisfied. She takes care of any emergencies, and patients are often relieved to see her clip an archwire or fix a broken bracket. She has had some good times working here, where we have had ice cream parties, costume contests, pumpkin decorating, pool parties and more. She also loves being a part of a family that never takes anyone for granted and is never too busy for anyone.
