Gary Colleran BA (Hons), C.M.C.T - Managing Director

Gary Colleran worked for SmithKline Beecham from 1990 to 1999 and had a successful career in sales, sales training and sales management. In 2000 he established Sales interAction Limited, specialising in selling skills and the influence programme "Principles of Persuasion" from Professor Robert B. Cialdini; the worlds most quoted author in the field of influence. To address customer requests, Gary started Advance® development in 2005. It was conceived to provide a platform that allowed consistent assessment of In Call Performance and sharing of coaching report forms in a transparent manner between sales people, managers and coaches.

Sport has played a big part of Gary's life. He played rugby for Coventry FC, Bedford FC and Edwardian FC. He has completed seven marathons, and Lands End to John O'Groats (Lejog) three times. Knee injuries are catching up, but he still intends to complete Lejog for the fourth time this year!

Having worked extensively within the training and salesforce effectiveness ‘arena’ Ian is able to work with organisations to enable their people to reach their potential operating at both a strategic and tactical level.

An enthusiastic skier, Ian enjoys both the sporting and recreational side of Winter holidays as well as taking short breaks to explore the restaurants and bars – not to mention sites - of European cities. Ian is also a long suffering Liverpool fan although a consequence of living in the South is that support is restricted to shouting at the TV these days.
