“It is fitting that Michelle is being recognized for her many professional accomplishments, as well as for her strong and continuing record of high-impact service to the Greater Pittsburgh area,” said Casey Ryan, the firm’s global managing partner. “Michelle’s legal acumen and dynamic representation have made a positive difference for hundreds of businesses; her dedication to the common good has made Pittsburgh a better place for thousands of adults and children; and her many contributions to Reed Smith as a leader, mentor and role model have made us a better law firm. This award is exceptionally well-deserved.”

During her leadership of the chapter’s major fundraiser, the Pittsburgh Signature Chefs Auction—including serving as 2021 vice chair, 2022 chair, and a 2023 and 2024 executive leadership team member—the event has raised about $1.4 million to support advocacy, educational programs, medical research and the provision of health care services that advance and protect the health and welfare of mothers and infants. In 2023, Mantine began a three-year term on the board of the Western Pennsylvania market of the March of Dimes; in 2024, she chaired the market’s Nominating, Recruiting and Volunteer Engagement Committee; this year, she chairs the market board’s Movement Committee, which is responsible for volunteer recruitment and engagement and awareness-raising.
Mantine is also an active member of Women United and the Bridges Society of the United Way of Southwestern Pennsylvania, one of the nation’s largest donor networks.

Mantine previously served as a board member of YWCA Greater Pittsburgh and continues to support the nonprofit as an external adviser.
“I am honored to be recognized by the Pittsburgh Business Times,” said Mantine. “I owe much of my success as an attorney and community leader to my own role models, the Reed Smith attorneys who have mentored me along the way. They impressed upon me the need to pay it forward by mentoring others and supporting the community where I live and work. Today, it’s all about supporting others to achieve success and thrive.”
