Dr. Kathryn Benson

I have been in practice as a pediatrician for over 20 years. I love what I do and was one of those people who knew what I wanted to be when I was a child. I didn’t only know I wanted to be a doctor but knew that I wanted to be a pediatrician specifically. I love working with children and enjoy them at all stages of development from the newborn infant, to the stubborn toddler, to school age kids and adolescents. Many of my patients have grown up in my practice and now some of them are going on to have their own children and bring them to me as their pediatrician. In pediatrics you get to know the whole family and I know the parents as well as I do the children. When my patients grow up and move on to adult physicians it is just as sad to say good bye to their parents as it is to my patients.

I grew up in Michigan and Ohio and moved to Atlanta in 1980 where I attended Emory College. I did all of my training at Emory University which included college, medical school and pediatric residency. In Emory College I was involved in an organization called Volunteer Emory, which at the time was a newly formed organization. Volunteer Emory pairs Emory students with volunteer opportunities in the community. I volunteered at Grady Memorial Hospital in the Pediatric Emergency Room and was also in charge of coordinating the pre-medical Emory volunteers that volunteered at Grady. As a pediatric resident I was involved in Camp Independence, a summer camp for children with kidney disease. I worked a few summers in this camp which allowed children on dialysis to attend a summer camp.

 I continue to have an interest in volunteering and helping others. I currently volunteer weekly with Meals on Wheels and I am also interested in missions/helping others in the local Atlanta area as well as internationally. I went on a medical mission trip to Liberia with a church group in April of 2014 and I will be going to Honduras this summer to work in a clinic there. I also currently volunteer my time to teach Emory students in my office. I am a preceptor for Emory medical students, NP students and Pediatric residents on a regular basis.

 In my spare time I enjoy being outside. I enjoy cycling, hiking and kayaking. I love being in nature and enjoy exploring places I have never been. I like to travel, love reading and enjoy spending time with family and friends. I have 3 dogs which are all “rescues” and I am an animal lover. I have fostered dogs with a local animal rescue group. Other areas of interest for me are environmental and social justice issues and advocating for the rights of children. One of my favorite quotes is by Martin Luther King Jr. “Life’s most persistent and urgent question is, what are you doing for others?”
