As president of Wall Street Access, the financial services organization founded by his father Denis Kelleher, Sean has helped guide the firm through successful ventures in online brokerage, institutional research, global execution services and trading, fixed income, and asset management. In 1992, Kelleher joined the firm as a clerk and now manages a team of more than 50 analysts, traders, and salespeople. A graduate of Wagner College, Kelleher now serves on the college’s alumni board. He also served as co-chairman of the Staten Island Film Festival, served on the board of the Staten Island Zoo and co-founded the Gerry Red Wilson Foundation to support spinal meningitis research.

He is actively involved in New World Preparatory charter school, Camp Good Grief and Project Hospitality. Kelleher, who spent the summers of his youth in Ireland working in the bog, says the catalysts behind his love for Irish culture are his family and playing Gaelic football in his father’s village in County Kerry. He lives on Staten Island, New York with his wife Wendy and their three children, Maggie, Jack, and Denis.
