What People Say
Marc played a significant role in my professional career over the past ten years through his unique ability to lead and mentor. He was the type of leader that made you excited to show up every day because he set a culture that many are never fortunate enough to be able to find in a company. Marc was always accepting of feedback, was never afraid to jump in and try something new even if it meant we might change it again the next day if it didn't work. He had a drive that is difficult to explain, but is deeply rooted from the passion he has for his clients and team.
