Officers and members of CVC's Global Board volunteer their time for a minimum of two years. They organize and execute monthly events; provide on-demand assistance to members and chapter leads around the world; and liaise and develop partnerships with regional alumni clubs. They're the "glue" that keeps our community up and running.
