Sean R. is a President - Marcus Global LLC at MARCUS GLOBAL LLC. Colleagues describe them as "While serving as the Chief Administrative Officer at Trinity Wall Street, NYC, I had the privilege of hiring Sean Ryan as the organization’s first Director of Safety and Security. Sean built a new operation and an outstanding team that, in turn, oversaw security contractors for multiple sites in Manhattan, a site in Connecticut, and a site in Berkeley, California. Sean is a gifted leader and manager, working seamlessly with authority above him, executives at his level, and with his staff and contractors. Additionally, Sean treats everyone from the head of the agency to the custodians with the same level of respect, and genuinely cares for the people around him. As a colleague, Sean is easily the most responsive person I’ve ever worked with, literally on-call 24/7. Although he had more expansive and complex responsibilities at previous jobs, Trinity offered a unique challenge, to which he not only rose but set a very high bar. The main site in the Financial District served as an historic landmark and national treasure as well as a local church near Ground Zero where security was of the highest priority and needed to be invisible to parishioners. Sean was able to juggle these competing requirements while deftly navigating a sometimes-contentious community. No matter the situation, Sean was unflappable and proved comfortable making decisions, comfortable presenting up through board-level audiences for approval, and he took responsibility for his and his team’s actions. Finally, he is a pleasure to work with. He is knowledgeable about his field and craft, he is professional even when those around him are not, he maintains a subtle sense of humor in the face of trying situations, and he is ridiculously well read. I am pretty sure that he can carry a conversation on nearly any topic. In short, Sean would make an excellent additional to any leadership team, anywhere."
