KimberlinKimberlin Moore, Treatment Coordinator
Hello, my name is Kimberlin. I moved down to Atlanta from Illinois in September 2018 and have been here at Quest Orthodontics since October 2018. My position here at Quest Orthodontics is the Treatment Coordinator, but my favorite thing about my job is meeting all of the new families that walk through our door. I enjoy spending my time outdoors either hiking or at a sporting event. GO CUBS GO!!! I can’t wait to help start your journey here at Quest.



Clinical Team

KristinKristin Tinsley, Clinical Assistant
Hi, my name is Kristin! I joined the Quest Orthodontics team in August 2017 and I couldn’t be happier. I love assisting Dr. Patel and watching our patients transition into a healthy, beautiful smile! In my free time I enjoy not only watching but playing soccer. I also have an amazing greyhound named Carm!


VashtiVashti Pirtle, Clinical Assistant
I started my journey as a pediatric assistant in 2012 and fell in love with ortho. I joined Quest Orthodontics as an assistant in early 2018, and truly enjoy being a part of our patients’ life changing experiences. I stand with my team as we strive to make every experience as fun and comfortable as possible. I enjoy living in Atlanta with my husband, trying new restaurants, exploring hiking trails/parks of Georgia, and most importantly spoiling our pup Charlie Frankenstein.


AngelAngel Chattam, Clinical Assistant
My name is Angel, and I joined Quest Orthodontics in August of 2018. One of the most rewarding parts of being an orthodontic assistant is watching our patients’ smiles transform, and knowing that I was a part of their journey to a beautiful smile. Dr. Patel, my coworkers, and our patients are the best. We have an amazing team! When I’m not helping create beautiful smiles, I enjoy spending time with my fiance, family, friends, and my French Bulldog, Nala. Oh, and Go Dawgs!
