Our Nurses

Hannah Thompson, LPN

I am a happy mama to my boys Rowan and Eli. I have a decade’s experience as a nurse, seven of which have been in a pediatric setting. Growing up I always knew two things. I wanted to help take care of people, and I wanted to be a mother. That led me to my calling— helping to take care of your sweet babies at Phillips Pediatrics. I’m so excited to work with an incredibly loving team of people.

Kara Barbee, LPN

I am a full time wife, mom and nurse, my three favorite things! I became a nurse in 2020 and have 9 years of experience in the medical field. Pediatrics has always been a passion of mine so when the opportunity to work at Phillips Pediatrics came up, I knew God was opening an amazing door in my life.  Every day it is so rewarding making your child’s appointment special, watching them grow and helping put a smile on their face.



Alexus Malone, LPN

I am a recent nursing grad and very excited to begin my nursing career in pediatrics. I am a proud wife and loving mother to Morgan Jayde. I enjoy taking care of children. I am excited to watch your children grow here with us at Phillips Pediatrics!


Claire Jones, LPN

I knew as a teenager that Pediatric Nursing was my calling. It’s even where I landed on my career aptitude and personality test in high school. I love taking care of children and love being a nurse, a wife, and a mama to my sweet Avery Claire. As fate would have it, I met Dr. Phillips in the well-baby nursery 2 days after Avery was born. I knew at that moment that we had found our pediatrician, and ironically, I became her pediatric nurse that same year.  Together, we opened the doors of Phillips Pediatrics. I miss seeing all of your kiddos but am enjoying some much needed family time and helping Taylor Jones State Farm Agency grow in Fulton, MS.
