Both have their merits: Jonathan has a background in operations and construction management with the US Army. His degree in business and years of experience puts him in charge of the day to day operations, scheduling, and administrative actions of the company. Anthony has his background as a handyman and creative artist. With his charm, eagerness, and attitude, he runs the marketing and advertising sectors of the company.
