Our staff is built to teach each student individually, to develop the skills they need to thrive in mathematics, and to foster a love of learning.

Keegan Collins

Assistant Center Director

Keegan holds a bachelor's degree in Physics from the University of Notre Dame, class of 2018. He brings over 10 years of tutoring experience and previously spent two years teaching math and science at St. Paul VI Catholic High School in Chantilly, VA.  

He loves the creativity that math inspires and enjoys guiding students through meaningful, problem-solving experiences. Mathnasium allows Keegan to blend his love for education with his analytical background. In his free time, you’ll find him enjoying board games or educational podcasts, always looking for new ways to challenge himself and grow. 

Matt Fitzgerald

Area Manager

Matt earned an Associate Degree in Computer Science from Northern Virginia Community College. Drawn to Mathnasium by his love for math and desire to make a meaningful difference in students’ lives, Matt is passionate about helping kids gain confidence in their abilities. 

As someone who struggled with math in middle school, Matt understands firsthand the impact that positive guidance can have. He now strives to be that supportive figure for his students. Outside of work, Matt enjoys video games, puzzle-solving, and exploring the strategic layers of game theory. 

Ben Bramsen

Senior Regional Director

Ben began his career in education by volunteering with marine animals—especially walruses—at the Indianapolis Zoo. That experience ignited his interest in teaching and environmental awareness, eventually leading him to a career where he could directly impact students' growth and development. 

At Mathnasium, Ben values the opportunity to witness students' progress every day. His approach blends education with curiosity and fun. In his free time, Ben enjoys exploring nature, traveling to new places, and playing guitar—even if he jokingly claims he’s still learning. 


Jeff McCabe

President

Jeff holds an Economics degree from James Madison University and a Master’s in Education from George Mason University. After ten years teaching math at both the high school and college level, Jeff transitioned into leadership roles in the restaurant industry before returning to his true passion—math education—through Mathnasium. 

Now, as President, Jeff leads with a commitment to student success and organizational excellence. When he’s not working to “Change Lives Through Math,” Jeff enjoys spending time with his wife of 28 years, their two dogs, and visiting their three adult children. 

James Temple

CEO

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.
