The number speaks for itself! 8 is the number of years I been fortune to have had the opportunity to experience training programs with these two top-notch coaches and trainers during my time with GroupM. None of the workshops they run would never let you down as they will always provide you a world-class training experience. If I have find to someone to run a training workshop for me, The Hummingbirds would be on the top of my mind without any other choice. Superb!
