Plunkett Cooney partner and appellate attorney Mary Massaron was recently named by Michigan Lawyers Weekly (MiLW) to the publication’s 2025 Hall of Fame Class.

Massaron is one of 26 attorneys selected by MiLW as a top legal leader in Michigan who has been practicing for 30 years or more. Candidates were selected because they built exemplary careers with numerous accomplishments and valuable contributions made to the legal industry, businesses, their individual law firms and community.

MiLW will host a Hall of Fame awards ceremony on April 25 at The Mint at Michigan First Conference Center in Lathrup Village, Michigan. This year’s honorees will also be profiled in a special section of the April 21 issue of MiLW.

A former law clerk to Justice Patricia J. Boyle of the Michigan Supreme Court, Massaron has handled or supervised the handling of over 400 appeals, resulting in approximately 150 published opinions, including over 100 appeals in the Sixth Circuit Court of Appeals. Massaron’s appellate advocacy is widely known. She has won numerous victories before the Michigan Supreme Court for public- and private-sector clients, overturning multi-million-dollar judgments and establishing new legal principles. 

In addition to this honor, MiLW selected Massaron as a Leader in the Law in 2009 and she has twice received Western Michigan Cooley Law Review Award Distinguished Brief Award for the best briefs filed in the Michigan Supreme Court. She has also been recognized by Best Lawyers in America for Appellate Law and has been repeatedly acknowledged as one of Michigan’s top 100 lawyers, top 50 business lawyers, top 25 women business lawyers, top 50 female lawyers, and top appellate law practitioners by Michigan Super Lawyers. She was recognized as the Best Lawyers 2017 and 2021 Appellate Practice “Lawyer of the Year” in Bloomfield Hills, and DBusiness Magazine named her top appellate lawyer for the past five years.
