Journey to success

Global Building Services is a private minority-owned business that has valued the representation of its individual employees over investors for over 35 years. GBS was founded by Julio Belloso, an entrepreneurial success story of someone who achieved the American dream. Starting from humble beginnings, Belloso immigrated from Guatemala with no formal education to lay the foundation for this company that set its roots servicing just a single client with the help of only two other supervisors. Today, Global building Services operates nationwide servicing some of the most well-known Fortune 500 companies. We contribute our achievements and success over the last three decades to our committed staff members, some of which who have served with the company since its early inception. We benefit from a company-wide dedication to hard work and a high standard of what good looks like. We are proud to serve our clients each day and are committed to providing opportunity for success to every employee who wears the Global Building Services uniform.
