About Gregory Rosko

As a partner with Deloitte, I have the unique opportunity to connect a passion for learning and teaching to providing valuable tax counsel to my clients. Clients view interactions with me as a chance to leverage the deep knowledge and insights I have gained from over two decades of advocating for multinational corporations and shareholders. Expect a collaborative and transparent experience and leverage me as go-to advisor for translating complex accounting and tax matters into practical, actionable advice. I am also committed to developing the next generation of business professionals—taking an interest in each team member’s career, investing time in training and mentoring, as well as leading campus recruiting efforts. Community and family are also vital to me; I seek to make a difference by serving on the Advisory Boards for Cleveland Central Catholic High School; EasterSeals of Northern Ohio; and, Greater Cleveland Sports Commission; and, finally, coaching my children’s sports teams; and, also being involved in the local community through his church. I’m ready to collaborate when you are, please write or call: g•••••@deloitte.com or 21••••••44.
