Peter Alford – CCO

Peter graduated from Macquarie University, Sydney in 1977 with a Bachelor of Arts (Environmental Science) and a Diploma of Education. The BA course consisted of a range of science, mathematics, accounting and computing subjects. While the computing industry was still in its infancy during the 1970s, the wide range of courses gave an excellent grounding to an IT based business career that started in 1980.

Early industry experience was based around the import and distribution of US based vendor products. With a series of sales and sales management roles, Peter progressed to a management role as divisional head of a Public Company. These roles gave Peter a solid grounding in technology, business and people management skills. Peter was directly involved in the introduction/distribution of very successful brand products such as Epson, Novell and Citrix to the Australian market.

After 13 years in various distribution businesses, in 1993, Peter moved into the integration and services sector of the IT industry. The integration and services business involved sales, sales management and leadership roles for local ‘start up’ businesses. Since 2003 Peter has been involved in building one of the first On-Demand IT businesses in Australia, then joined the management team of ITonCloud in early 2009 as a continuation of his passion to build a Cloud Computing Business.
