Marc was a highly effective executive coach for me during a period of significant transition in my professional life. Marc identified areas that would benefit from focus. He validated the results of baseline assessments and monitored my progress with a carefully-managed 360 feedback process, assessing my progress objectively over the course of our work together. The changes that I have effected in myself with Marc’s guidance have been remarked on positively by many. More than 2 years after completing my work with Marc, I can say that his coaching was effective and lasting.
