Debbie Sebastian, Insurance & Billing Coordinator
I have worked with Dr. Williams since 2000. When she moved to Indianapolis I assisted her in purchasing her practice and fulfilled my duties remotely until March 2012. At that time I moved to Indianapolis to assist her with the addition to the clinic and fell in love with the city and the people of Indiana. I have worked in the dental field for over 30 years. I am very passionate about working with Dr. William’s and her staff. To work in an environment that puts the patient first and delivers the best possible care, is a dream come true. In 2014, my family welcomed the addition of my 7th grandchild, at that time we moved back to Arkansas to be close to family. I continue to work for Dr. Williams remotely, handling all of the office billing and insurance.   I consider myself blessed to work for such an understanding person as Dr. Tracey Williams.

Charlotte, Office Manager
I attended dental assisting school at Indiana University School of Dentistry and worked as an expanded functions dental assistant from 1999 to 2005. I was promoted to office manager in 2005 and have worked in both an administrative and clinical capacity since that time. I joined Dr. Williams’s practice in 2012 as a clinical coordinator and feel very fortunate to be part of such a great team that truly strives to deliver the best patient care possible. In my free time I enjoy traveling and spending time with friends and family members.

I was born and raised in Indy. I graduated with honors from PCI in 2004 and entered the world of dentistry. I am extremely well versed in the dental field having worked everything from surgery to general practices in both front office management as well as dental assisting for over 10 years. I joined Dr. Tracey Williams’s amazing team in March of 2014 and couldn’t be more excited to be part of such a fun-loving and cohesive group, dedicated to changing lives, one smile at time. When I’m not passionate about dentistry, I am at home raising three wonderful boys with my husband of 14 years. Together, he and I coach and manage all their travel soccer teams at USAI. I also enjoy reading, working out, and the great outdoors.
