She moved into Executive Search in 1983, initially as Research Manager and then as Consultant with The Caldwell Partners, a leading Canadian search firm, working with the team that went on to form Bucher Rugman and subsequently Thewlis Graham.

Karen has completed searches across a broad range of organisations in her 30+ years experience, including the Private and Public sectors and more recently the third sector. She has completed assignments to find CEO’s, COO’s, Chairmen, Trustees and Heads of function.
