"Simply put, the effective presentations Mark produced for us became instrumental in describing our business-growth story. He successfully took ideas steeped in 'real-estate business jargon' and made them more accessible to a much larger audience, which improved our bottom line.

Mark again delivered strong results co-authoring and editing my book on 'Unique Value Propositions,' which made Amazon's BestSeller List. He's a rare talent, who comes highly recommended."
