Petno was born on February 7, 1965. He later studied at Wabash College, a men's liberal arts college in Crawfordsville, Indiana, and then pursued graduate business study at the University of Rochester in New York state.
Petno earned a Bachelor of Arts degree in biology from Wabash College. Founded on November 21, 1832, Wabash is a private, independent liberal arts college for men in Crawfordsville, Indiana. The college was patterned after the conservative liberal arts colleges of New England, and although its founders were Presbyterian ministers, it has always been independent and non-sectarian.
He then earned a Master of Business Administration from the University of Rochester's Simon School of Business. The school began as a small business program at the University of Rochester in 1958 and awarded its first MBA in 1962. In 1986 it was renamed the William E. Simon Graduate School of Business Administration, and its approach has long leaned heavily on economics and the application of empirical research.
Petno's career included various positions at Morgan Stanley & Company. Morgan Stanley was founded in 1935 by Harold Stanley, who had been barred from the securities business for more than a year, together with partners from J.P. Morgan. Its founding followed the Glass–Steagall Act, which separated commercial banking from investment banking.
Petno began his professional career with J.P. Morgan in 1989 in Oil & Gas Investment Banking. Over the following two decades in global investment banking, he held several senior positions and rose to lead J.P. Morgan's Global Natural Resources Group. The natural resources unit covered clients in oil and gas, power and utilities, chemicals, metals and mining, building products, and paper and packaging. In that role he advised on some of the largest transactions in the natural resources industry over the past decade. He was recognized by Dealmaker magazine in 2006 and 2007 for his energy and power deal-making.
In 2005 Petno became managing director and group head for energy at J.P. Morgan Securities Inc., a subsidiary of JPMorgan Chase & Company. J.P. Morgan Securities was part of a banking group that provides banking, asset management, investment banking, credit card and mortgage services.
From 2012 to 2024 Petno was CEO of Commercial Banking, having previously served as its chief operating officer. Under his leadership the business expanded significantly in the United States and entered 27 countries, serving more than 60,000 clients, including mid-sized businesses, corporations, founders, government entities, not-for-profit organizations, and real estate investors.
Later he served as Co-Head of Global Banking in the Commercial & Investment Bank and as Co-CEO of that division. The Commercial & Investment Bank encompasses Global Banking, Markets, Payments and Securities Services. In 2026 he was appointed sole head of the business and serves as Co-President of JPMorgan Chase, as well as a member of the firm's Operating Committee.
Petno was a member of the National Petroleum Council, an advisory body established in 1946 at the request of President Truman. The Council advises the U.S. Secretary of Energy on matters related to oil and natural gas, and its members serve as representatives of their industry rather than of their individual companies. Petno served on the Council while at J.P. Morgan Securities as managing director and energy group head.
Petno has served on the Global Board of Directors of The Nature Conservancy, a conservation organization, and has been a director since 2018. He is also a director of the JPMorgan Chase Foundation, the philanthropic arm of the banking group.
He was formerly a director of the American Bankers Association, a banking trade association that represents the banking industry.
