Meet the Team

David Glendenning

President / Director

David began a career in telecom in 1994 and over the past 25 years has become an expert and influencer within the industry.

Early in his career, David witnessed that poor levels of service and support often plagued the industry. He founded CSG to provide clients and partners with a superior experience. He has stayed at the forefront of emerging technologies to work as a well-informed advocate for the buyer as well as holding vendors accountable. With his leadership, CSG has grown each year since its inception. He and the team strive to provide a white-glove level of service while offering best in class solutions.

Over the last 10 plus years, Mr. Lewis was instrumental in helping grow their carrier services division into an organization generating millions in revenue and supporting mid size to Enterprise companies around the globe.

During the course of his career span he has worked directly with 120+ services providers and over 300 customers.
