Our Law Firm was founded by attorney William J. Leininger in 1981. Mr. Leininger is a native New Yorker who graduated from Regis High School in Manhattan and St. Francis College in Brooklyn.  In 1974, he graduated from Fordham Law School with the rank of #1 in his Evening Division. He was admitted to the New York Bar in 1975 and was subsequently admitted to the Bars of New Jersey and Florida. Mr. Leininger has appeared on the Phil Donahue Show, the Sally Jessy Raphael Show, the Today Show on NBC, the CBS Morning Show, and other national television and radio programs, and has lectured on Divorce for over 40 years. Mr. Leininger became a certified Divorce Mediator in 1994. Since then, he has mediated over 850 cases to completion. We believe that he is one of the most experienced attorney divorce mediators who mediates online with New York residents getting divorced.
