Meet the Team

Mary Carkhuff : Registered Dental Hygienist

I have been working in the dental field for over 25 years. I was originally inspired to work in dentistry by my own dentist when I was in high school. I had a lot of dental work done, and spent a lot of time sitting in "the chair." My practice had such a wonderful atmosphere that I knew I wanted to work somewhere just like that someday. Our practice here reminds me of my childhood dental practice. We all have a good time here, and we all enjoy what we do. I have developed so many meaningful friendships with my patients, and I feel like each of them have become part of my family. I am originally from Germantown, Tennessee, and recently moved to Thompson's Station. My husband, Chuck, and I have three children: Katie, Lauren, and Chuck III. We also have a Weimaraner named Aubrey. I enjoy playing tennis, reading, and walking my dog. 

Becki Voorhis : Registered Dental Hygienist

I was born and raised in Bakersfield, California and moved to Brentwood just after completing High School. My mother is a dental hygienist, and from watching her interact with patients, I fell in love with the dental field too. After completing an Associates of Applied Science at Columbia State Community College, I attended the Dental Hygiene Program at Tennessee State University and graduated Summa Cum Laude with a Bachelors in Dental Hygiene. I was awarded the Dental Hygiene Directors Award, which is an instructor nominated award given to one graduating dental hygiene student who has exhibited leadership potential as demonstrated by her participation in student, departmental and community activities. When I'm not working, my husband Calvin and I love going on hikes and exploring the outdoors with our pup, Oakley. We enjoy living in Franklin and both actively participate at our church and in the community.

Lauren Smith : Registered Dental Hygienist

I have been a Registered Dental Hygienist since 2009. I started working part time at a local dental office while going to college and knew almost immediately that working in the dental field was something I had to do. After graduating college, my husband and I lived out of state for several years. We returned to Franklin in 2017 and I joined Cool Springs Family Dentistry in the summer of 2018. In my free time I love to travel, read, ride horses, and hang out with family and friends. I have been married to my husband, Jay, since 2006 and we have a son, Spencer.

Jessica Netterville : Registered Dental Assistant

I have lived right here in middle Tennessee for my entire life. My husband Tanner and I have been married since 2018 and recently moved out to Ashland City to spread out a bit. I enjoy spending my free time gardening and living a simple life with my husband, two dogs and two cats. I have been a dental assistant since 2006 and I still love it!

Michelle Null :  Front Office

I grew up in Minnesota, ten minutes outside of Minneapolis ... you know, the land of 10,000 lakes. My husband and I moved to the Nashville area 25+ years ago to pursue his music, and we never left. Shortly after arriving here in Tennessee, I found myself working in the dental field... and I'm still here! We have a ten year old son, Jacob, who is working hard towards his career as a professional gamer. My hobbies include crafting, gardening, cooking, and enjoying the early morning hours on my patio. I am very involved in my church, where I serve as an Elder and member of the choir.

Abby Kamel : Front Office 

I was born and raised in Montgomery, Alabama. After high school I attended the University of Mobile in Mobile, Alabama. I have been involved in dentistry for 5 years. The first 2 years I was a dental assistant for a pediatric office in Alabama, and in September of 2019 I moved to Tennessee where I transitioned into my role at the front desk here. My favorite thing to do when I am not at work is art and calligraphy!
