After graduation from MIT, Raysman worked for the IBM Corporation as a systems engineer for six years, based in New York City.
In that capacity he guided the information technology departments of major corporations in implementing new computer systems and upgrading to more advanced hardware.
During that time he joined the U.S.Army Reserve, where he served in the Military Police for six years, doing his basic training at Fort Gordon, in Augusta, Georgia.
Since the use of computers in a business context was increasing exponentially, Raysman decided, in 1978, to start his own firm in New York City specifically to counsel companies in those transactions.
He is also a regular speaker in this field at numerous conferences, including those sponsored by the International Bar Association, the Outsourcing Interests Group and the Intellectual Technology Law Forum in Europe.
Raysman is married to the former Georgia M. Urbano, a graduate of the Columbia University School of Law and Connecticut College, who is also the former President and Chairman of the Nantucket Preservation Trust.
