About Us:

Greg York
Managing Director

Greg came to the Asia Pacific Region in 1982 with Rank Xerox Australia and Rank Xerox Singapore. Seeing the enormous possibilities for Computer-Telephony applications while working at Rank Xerox Asia headquarters in Hong Kong as Regional Product Manager for Xerox IT systems, Greg founded Interpac in 1986 to develop software systems for telecom applications. Following a philosophy of combining top software development talent with the best proven development tools, of closely incorporating customer feedback into every stage of the product development lifecycle, and of taking a world view of designing each product from the outset for global rather than just local markets, he has guided the company from its beginnings as a one-product supplier to Hong Kong Telecom to one of the most trusted providers of call management applications in 16 countries across Asia Pacific. Greg holds a Bachelor of Administration Degree with Distinction from the University of Regina in Canada.
