Dr. Janna Cate Routh

I am Dr. Janna Cate Routh. I’m really excited to be joining Fenton Family Dentistry as a dentist. I am originally from Georgia and graduated from the University of Georgia with a Bachelor’s degree in nutrition science. I then moved to Missouri to attend the Missouri School of Dentistry and Oral health where I received my Doctorate of Dental Medicine. During my time in dental school, I enjoyed living in the St. Louis area, so much so, that I decided to stay in the area to practice! I am looking forward to forming lasting relationships with patients while helping them achieve healthy, beautiful smiles. I am currently a member of the American Dental Association, the Missouri Dental Association, the Greater St. Louis Dental Society, and the Academy of General Dentistry. During my free time, I enjoy exercising, traveling, and spending time with friends and family.

Hi! I am Paige. One of Fenton Family Dentistry’s front staff members. I discovered my love for dentistry early in life. I always looked forward to going to the dentist and had so many fond memories being a patient in my pediatric office. I feel that it is my mission to help make everyone feel comfortable and stress free when they come into our office. When I am not at the office, you will most likely find me somewhere outdoors. I like to try and stay active by hiking or biking. One of my favorite things to do in the summer is to go boating and water skiing down at Table Rock Lake with my family.
