The Board

Greg Haliday
Greg Haliday
Owner and Manager Director

With extensive experience and proven performance in a number of roles with nationwide freight companies, Greg co-started Mainstream in 1992.

Greg's approach is innovative and solution-driven. His unrelenting can-do style and strong work ethic meant the business grew rapidly, successfully moving freight that was typically perishable, urgent, or just simply difficult.

His leadership style is very much hands-on and forthright. Day-to-day activities still include managing clients, many of whom had faith in Greg and Diane when they began using Mainstream in the early 1990s.
