Angela S. Christian, RDH, BS

Dental Hygienist

After graduating from Thomas W. Kelly High School, I continued my education at Southern Illinois University in Carbondale where I received my Bachelor of Science degree in Dental Hygiene.

My husband and I have two children. Spending time with my family and friends is an important part of my life. My summers are spent at the ballfields cheering for my favorite baseball and softball players. In my free time, I enjoy playing the piano.

My favorite part of being a dental hygienist is the joy that I feel when I am educating and taking care of my patients. It is important that each one feels special, cared for and happy as they leave their dental appointment. I strive to do the very best that I can so that each patient leaves with their teeth feeling clean and with a shiny, beautiful smile!

Dental Hygienist

I completed my Dental Hygiene degree from Missouri Southern University in Joplin, Missouri. Spending time with family, traveling, and doing outdoor activities is my favorite way to spend my time outside of the office. I also really enjoy trying international cuisines and my favorites are Indian and Thai foods! The most rewarding part of dentistry for me is being able to help and support our patients on their smile transformation journey.
