Akida Mashaka
Founder
(pictured on the left)
BHS is the brainchild of Akida Mashaka, an American free-spirited entrepreneur from Los Angeles, California and author of the BHS Method for Startups. Akida founded BHS to create the best learning environment for his teenage son. During Covid, he started BHS with only 5 students in a basement and 4 years later BHS has grown to over 300 students based on Akida's vision to have the best learning environment and school experience for students.
After living in Barcelona with his family, Akida experienced the antiquated teaching methods and major flaws of traditional education in schools, which were clearly exposed during Covid. Accordingly, Akida created a school to solve the problem that he had in finding the right school for his son.
Akida wanted a school with smaller class size focusing on individualized and communal learning in a family-like environment. Through a student-centered culture, innovative digital educational tools, independent learning, social engagement, and emotional confidence, Akida founded BHS to foster the skills necessary to be successful in today's modern world, not the world of the past.
While the name "Akida" means leader, Akida is a graduate of Harvard Law School and attended university on a tennis scholarship. Akida graduated #1 in Psychology for his Bachelor's degree at Morehouse College. Therefore, a one of kind work-life culture committed to academic empowerment, social confidence, emotional growth, mental health, along with athletics, extracurricular and after-school activities are collectively the backbone of BHS.

Principal

Ciarán has developed the school’s Mathematics and Science Departments based on nine years of tutoring mathematics and physics to both high school and university students in Ireland. Ciarán currently teaches advanced Mathematics courses such as AP Statistics. He also trains teachers on the BHS Method™ while overseeing Professional Development and the curriculum of the school.
