James Dinan is an American hedge fund manager and the founder of York Capital Management, located in New York City. Dinan is also a partial owner of the NBA’s Milwaukee Bucks. Dinan was born and raised for the first 10 years of his life in Baltimore, Maryland before moving to Worcester, Massachusetts.
Dinan graduated from Bancroft School, a private school in Worcester. James then enrolled at the Wharton School of the University of Pennsylvania where he earned his Bachelor of Science in economics. In 1981, Dinan took his first job with Donaldson, Lufkin & Jenrette (DLJ), a stock research firm. He later would earn his MBA from Harvard University. In 1987, Dinan lost his entire $600,000 in savings when the stock market crashed. However, Dinan recovered in 1991 when he raised $3.6 million from his former colleagues at DLJ and started his own hedge fund, York Capital. By 2000, the fund had over $610 million in assets. Ten years later, he sold 33% of York Capital to Credit Suisse for $425 million. Dinan is a big supporter of the Museum of the City of New York and has supported them through the charitable organization, Portfolios with Purpose.
