Strategy Consulting Testimonials

Between 2004–2008 I had the pleasure of working with Graham on a number of projects ranging from portfolio strategies to individual product assessments. Graham provided value to our team through his ability to work with cross-functional stakeholders, identify key business questions and areas of uncertainty, and translate these issues into an appropriate modeling framework. In addition to his masterful Excel skills, his ability to apply rigorous analytics to extract meaningful business insights is where he truly shines. I look forward to working with Graham again in the future!

Graham helped us in modelling some challenging projects. He understood the business extremely fast and helped us in asking the right questions. His modelling skills are fantastic. On top he is a good team player which worked really well with our team.

I have known and worked with Graham for over a decade. In addition to being a great person, he is an outstanding decision analyst and a master business modeler. In particular, Graham’s Excel models are functional works of art that often serve as the basis for decisions well beyond their initial intended purpose. Over the years, he has been reliable and trustworthy. While our professional opportunities have lately taken us on different paths, I look forward to the day when we can work together again and, maybe, have some sushi and a beer.
