Andrew Piltser Cowan is the co-founder and principal attorney at the law firm of PiltserCowan in Cambridge, MA, where his practice focuses on wills, trusts, and estates as well as criminal defense. He happened into the niche field of estate planning for writers when he got involved in litigation over the estate of a deceased English professor, and has since gone on to represent several writers and musicians. Prior to founding PiltserCowan in 2013, Andy worked as a Massachusetts public defender for five years. He lives in Belmont, MA with his spouse, Jade, the co-founder and business architect for PiltserCowan.

Andy received his bachelor's degree in physics and astronomy from the University of Iowa, and his law degree cum laude from Cornell Law School, where he was an editor of the Journal of Law and Public Policy and received the school's Freeman Award for Civil-Human Rights. While in law school, Andrew also received a commendation from the Louisiana Supreme Court for his volunteer work in the wake of Hurricane Katrina. In 2012, Andy received Cornell Law School's Rising Star Award for Exemplary Public Service, and in the same year shared the Massachusetts National Lawyers Guild’s Legal Worker Award with the other members of the Occupy Boston Legal Working Group.
