Our firm traces its roots to 1931, when Orville H. Mann, Sr. established his practice in the village of Nyack, New York along the Hudson River, where he practiced for 48 years. Orville H. Mann, Sr. served as Rockland County Bar Association and graduated from Princeton University and the Columbia University Law School. In 1961, his son, Orville H. Mann, Jr., also an graduate of Princeton University, joined his father to continue their legacy under Mann & Mann, P.C. In the early 80’s, Attorney Robert P. Lewis, Jr. brought his legal and judicial experience to the firm to form Mann, Mann & Lewis, P.C.
About 10 miles west of Nyack, in the hamlet of Pearl River, New York, Orville H. Mann, Jr.’s uncle, Edmond L. Mann, and Attorney Marshall Rooney, were partners at the firm Mann & Rooney, dating back to the 1940’s. In the 1970’s Attorney Rooney joined the firm Amend & Amend, where Attorney James K. Riley and Thomas F. O’Connell were partners.
In 1978, Mr. Riley and Mr. O’Connell left Amend & Amend and established their own firm, O’Connell & Riley on East Central Avenue. Three years later, in 1981, Attorney Marshall Rooney also joined O’Connell & Riley bringing almost 50 years of local relationships to the firm. For over 40 years, Attorneys O’Connell & Riley provided estate planning, elder law and litigation services to the greater Rockland County community.
In 2001, Attorney Joseph M. Donohue began his legal career, working in the New York and Paris offices of Leboeuf, Lamb, Greene and MacRae, LLP. Driven by his entrepreneurial spirit, Joe founded his own practice in Warwick, New York, in 2007.
The firm established a presence in the Granite State in 2013, to take advantage of New Hampshire’s favorable tax and regulatory climate for trusts.
