"The Bottleneck Guy," Author and Business Consultant
"Graham has a quiet and very, very clever way of helping other people solve gnarly problems. A lot of people can solve problems, a few people can solve gnarly problems, but very few people can help others solve them."

"Graham is the kind of teacher that we need more of. He takes the time to listen; to understand; and to guide you to challenge your assumptions and your approach. He is clear and logical in how he helps people to think; and to find their own breakthrough to business success. I hope to have more time with him."

Mirta Fagundes
Director — Viago International
"We have worked with Graham in many different capacities for over a decade. Graham has a natural ability to handle any situation with calm. He is a deep thinker with a passion for problem solving, which has helped many of our clients resolve persistent, deep-rooted issues."
