Rennie Cook

Results matter most to Rennie Cook, and he builds leaders and teams that deliver them. Through Triumph Team, he serves small and mid sized companies in professional service environments such as education, financial services, oil and gas, and related sectors where people are the real differentiator. He shows up when performance is inconsistent, communication is muddled, and leaders are spending more time managing problems than moving the business forward. Many organizations respond with one off workshops and inspiring keynotes. Rennie sees that as a distraction from the real work of reshaping how leaders think, act, and operate every day.

At the core of his approach is a tight integration of consulting, training, and coaching that actually changes behavior. Rennie is skilled at reading the room, spotting patterns in how decisions are made, and identifying the gaps between what leaders say they value and what their teams experience. He builds development plans that are specific to the company’s goals and context, not generic content pulled off the shelf. Through targeted training and ongoing coaching, he helps leaders raise expectations, clarify roles, and build practical rhythms that drive accountability and execution. Clients see stronger alignment, healthier team dynamics, and a noticeable lift in how confidently their people handle complexity.

When stakes rise and patience for trial and error runs out, Rennie brings a direct, grounded presence that keeps everyone focused on what moves the needle. He strips away vague language, gets leaders talking honestly about performance, and gives them tools they can put into play immediately. The leaders who work with him report clearer direction, fewer surprise issues, and teams that show up ready to perform, not just participate. If you want training and development that translates into real traction in the business, Rennie is the partner you want in the room.
