Rex Schoolcraft

District Manager
Rex is a dynamic educator and versatile leader whose journey through diverse fields has culminated in a passion for mathematics education. He holds a B.S. in Mathematics and a B.A. in Secondary Education, both through the University of Wyoming. While he started in education as a high school math teacher, Rex was drawn to Mathnasium because our curriculum gives him the words that match the way he thinks about mathematics, and he thrives in an environment that is able to help thousands of kids each and every day. Outside of the center, Rex loves to read, pick at the guitar, and play simulation games on the computer. He also has a dog who he spoils relentlessly!

Nicki Atwood

COO, Owner
Nicki hails from Baltimore and studied Physics and Chemistry at University of Richmond. While working with students in college, she noticed that many times students are held back because of a gap in their educational foundation and that drew her to Mathnasium’s unique approach. When not at Mathnasium, Nicki loves to visit different cities and hang out with her cat. In fact, she loves pets of all shapes and sizes, and has had many different types of pets, including a dog, a mouse, a rabbit, and even a hedgehog!

James Temple

James developed a passion for and proficiency with Mathematics during his middle and high school years. In 2000, James graduated from the University of Virginia with a degree in Mathematics and a love for solving all types of problems. He took those skills into the United States Air Force where he served for 7 years as an aircraft maintenance officer. It was during these years that James had the opportunity to tutor home schooled children and really started to appreciate the frustration that many kids feel towards Mathematics. James left the Air Force in 2007 to go back to the University of Virginia where he received his Master's of Business Administration degree from the Darden School of Business.

Our Mathnasium Mission

Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.

What I love about Mathnasium is the ability to teach problem-solving skills and make math make sense, while also making a student smile.
