Meka worked in Navigation Games in 2024 and loved what we do, so he joined the Board. He's knowledgeable about our programs, passionate about youth development and full of energy!
John retired after a successful career working in the biotech/pharma industry as a finance director. Former Army veteran, John used to compete as an adventure racer in Team 24 hour races.
