About Siben & Siben Llp

Siben & Siben, LLP., was founded in 1934 by Sidney R. Siben after his graduation from New York University School of Law. Upon graduation from Brooklyn Law School, his brother, Walter, joined him in his office in Central Islip. After both Sidney and Walter were discharged from the Army, after World War II, they moved the office to Third Avenue in Bay Shore. When the firm outgrew the space on Third Avenue they relocated to our present location in 1964. Also in 1964 Sidney’s son, Stephen, graduated from New York Law School and joined his uncles and cousin in the family practice. Andrew Siben graduated from Hofstra Law School in 1985 and went on to join his family in this growing firm. Sidney’s grandson, Mark Rudner, graduated from Touro Law School in 1990,
