I appreciated his dedication, advice and the building up of our relationship.” 

Robert Schuler 

Robert understands me as a person and how I work. I'm not the easiest of individuals to work with but he not only advises mebut he also guides me knowing the way I think and execute. The only suggestion for improvement is if he could maybe clone himself.
