Edson joined the BEAM community back in 2013 and loved learning about each person’s story of how they came to be who they are, or how they even came to BEAM! Three years later, he joined the BEAM staff as a junior counselor. Along with teaching kids the fundamentals of mathematics and complex concepts, he also made them enjoy learning about cinema and the arts. In his free time, Edson writes his own scripts, produces his own short skits, and plays soccer. He is a total wild card!
