Early Life

Mark L. Attanasio was born on September 28, 1957, in The Bronx, New York City, before growing up in Tenafly, New Jersey. He attended Brown University, where he graduated with a Bachelor of Arts in 1979. He later pursued law, earning a Juris Doctor (J.D.) from Columbia Law School in 1982.

His academic background in both the liberal arts and law gave him the foundation to build a career that would span finance, investment, and professional sports ownership.

Career in Finance and Investments

Attanasio began his professional journey in finance, eventually co-founding Crescent Capital Partners in 1991, an investment firm based in Dallas. The company specialized in high-yield and mezzanine debt. In 1995, Crescent Capital was acquired by the Trust Company of the West (TCW), giving Attanasio a foothold in the upper tiers of financial management.

He went on to become a senior executive with TCW/Crescent Mezzanine and the Trust Company of the West, cementing his reputation as a skilled money manager. His expertise in structured finance and investments laid the foundation for his wealth, which he later diversified into the world of sports.

Attanasio also served on the board of directors of Global Crossing in the early 2000s, though the telecommunications firm famously filed for bankruptcy in 2002. Despite that setback, his investment career continued to thrive.

Ownership of the Milwaukee Brewers

In September 2004, Mark Attanasio led an investment group that reached a deal to purchase the Milwaukee Brewers from the family of then-MLB Commissioner Bud Selig for $200 million. The deal was officially approved by MLB owners in January 2005, making Attanasio the team’s principal owner.

Since taking over, he has been credited with stabilizing and revitalizing the Brewers’ operations. His tenure has been marked by a commitment to building competitive teams, strengthening community engagement, and investing in player development. He has also worked closely with general managers and coaching staff, including extending contracts for former GM Doug Melvin and manager Ron Roenicke.

In addition to the Brewers, Attanasio is also a part-owner of the Milwaukee Admirals, a minor league hockey team, alongside Brewers Assistant General Manager Gord Ash and former pitcher Ben Sheets.
