Our Roots
In 2004, Bob Kerr and Tim Greiner launched Pure Strategies. After collaborating in their work with a wide range of clients through Kerr, Greiner & Associates (KGAA), Tim and Bob have combined the resources and talents of their separate companies, Greiner Environmental and Kerr & Associates, under one roof. With more than 30 years of consulting experience between them, Tim and Bob look to lead materials flows and corporate practices towards greater sustainability.
