Our Team

Probe Research was founded in September 1994 by Scott MacKay, growing from a sole proprietorship into a core team of elite research consultants. During this time, Probe has evolved into a boutique, bi-national firm with offices in both Winnipeg and San Diego. In late 2018, Probe Research entered a new and exciting era as two new principals, Curtis Brown and Mary Agnes Welch, joined with Scott MacKay to form a new partnership.
