Jay P. Sheryll, Esq.

Attorney and Owner of Sheryll Law

As a husband and father of two daughters, Jay Sheryll understands the importance of family relationships and legacy. When he graduated Summa Cum Laude with a Juris Doctor degree from Touro College Jacob D. Fuchsberg Law Center, he knew he wanted to start his own practice and devote it to estate planning because, in his words, “having a family is all we leave behind.” He established Sheryll Law, P.C. in Riverhead, New York, in 2017, where he and his staff cater to clients’ estate planning needs on the East End of Long Island.
