Born in Southampton, he attended the public schools and studied medicine at Elizabethtown, New Jersey (later Elizabeth.)

He was undersheriff of Suffolk County from 1784 to 1787, and was sheriff from 1787 to 1792. He moved to Herkimer County in 1793 and settled in what is now the town of Lodi and continued the practice of medicine. He also erected and operated a grist mill.
