Pieter Gershon Weinrieb

Pieter G. Weinrieb is a divorce and family law attorney serving Buffalo, Williamsville, and all of Western New York. As the founding attorney of Weinrieb Law, he has more than 20 years of experience representing clients throughout Erie County and Niagara County in contested and uncontested divorce, child custody, child support, spousal maintenance, equitable distribution, prenuptial agreements, and divorce mediation. Admitted to the New York State Bar in 2005 and the Connecticut State Bar, Pieter is a 42-hour certified family and divorce mediator — one of relatively few attorneys in Western New York who is both a seasoned litigator and a certified mediator. He serves on the Attorney for the Child panels in Erie and Niagara County Family Courts, which gives him direct insight into how judges evaluate custody cases and what evidence actually moves outcomes. Pieter holds a J.D. from the Elisabeth Haub School of Law at Pace University, an M.A.H. from the State University of New York at Buffalo, and a B.A. from Hobart College. His graduate training in psychology and humanities background in English and religion shape his practice: family law cases are stories about people in crisis, and Pieter brings as much attention to the human side of a case as he does to the legal strategy. He is particularly experienced in high-conflict custody, high-net-worth divorce, complex asset division, QDROs, military divorce, same-sex divorce, and contested matters involving allegations of parental alienation, domestic violence, or hidden assets. Recognitions include Top 10 Family Law Attorney (Best of the Best Attorneys, 2026), Lawyers of Distinction (2026), the Association of America's Top 100 Lawyers (2019), the Avvo Client's Choice Award (2017), and an Avvo rating of 9.8 out of 10. Pieter has been featured in the Buffalo News. Weinrieb Law is located in Williamsville, NY, and serves clients in Buffalo, Amherst, Clarence, Cheektowaga, Tonawanda, Kenmore, Lancaster, Hamburg, Orchard Park,
