Science Department Teachers
Ms. Singletary
Hi! My name is Amanda Singletary and I am teaching Physical Science. I have been married 3 years and this will be my second year teaching as well. I have 12 reptiles and a tarantula, plus one cat at home. I enjoy sharing the experience of reptiles with children and adults alike as we learn a healthy respect for things in nature and in our homes when they are pets.
Mr. Paulk
I am a graduate of Emory University. I’ve earned a Master’s degree in math and science. I have a specialist certification in education and leadership. I’ve been teaching for 31 years. I’ve taught in south Dekalb, Buford, and for the last 6 years I’ve been part of the River Trail family. I’ve had students take the top honors at the state science fair, and last year we took the top spot at the state for chess. I look forward to another wonderful year with my River Trail Students and Parents.
Ms. DiMaggio
I am an alumnus of The University of North Georgia where I have a degree in biology and chemistry. Somewhere on the road of studying to become a veterinarian, working with tigers, and becoming a mother, I realized that my true passion was to teach. This is my 12th year teaching 8th grade science and my 5th year at River Trail! I live with my husband, 13 year old daughter Lorelei, 7 year old son Landon, 4 cats, 1 dog, a turtle, a hamster and several fish! I enjoy reading, crafting, and musical theatre. I also sponsor the Jr Beta Club and direct the spring musical!
Ms. Callaway

Donna began her professional life as a lighting designer for theatre and film before her second career in education. She loves hiking with her family, her husband, and kids aged 14 and 16.
