Diana Taylor is an American business executive who was the First Lady of NYC from 2002 to 2013 through her domestic partnership with politician Michael Bloomberg. She is also the former New York State Superintendent of Banks.
Biography
She was born on February 6, 1955, in Greenwich, Connecticut, USA, as Diana Lancaster Taylor.
Her great-grandfather was involved in financing the Spence School on the Upper East Side.
Her mother was a schoolteacher, while her father worked as a biochemist at Union Carbide in New York.
Old Greenwich is where she spent her childhood. Taylor told The New York Times in 2013: “Growing up, I imagined I would come to New York, get married, move to the suburbs and have kids. It just didn’t happen that way.” (NYT interview, 2013)
She graduated from Greenwich High School.
In 1977, Taylor earned an A.B. in economics from Dartmouth College.
“I absolutely loved it; but it was hard,” she said of Dartmouth to Robin Givhan in 2020.
She also has an MBA from Columbia Business School and a degree in public health from Columbia University.
While attending business school, Taylor worked part-time at Lutheran Medical Center in Brooklyn.
Business school started a family war.
Her father did not want her there, and she recalled in that same Givhan interview:
“It was the first fight I had with my father.” Round two, in her words: “We had a knockdown, drag-out fight, which was great.”
From 1993 to 1994, Diana served as the Executive Vice President of Muriel Siebert & Company.
Citigroup’s 2014 proxy lists her as an associate at Smith Barney, Harris Upham from 1980 to 1982 (SEC copy), and the Post says she later became a senior vice president at Donaldson, Lufkin & Jenrette, where she helped set up public finance department.
From 1988 to 1993 (and once more from 1995 to 1996) she was president of M.R. Beal & Company, a full service investment bank, per Citi’s 2026 proxy statement.
In 1996, she worked as assistant secretary to George Pataki — former governor of New York.
From 1991 to 2001, Taylor served as the Vice President of KeySpan Energy. At some point, the company was the 5th largest distributor of natural gas in the US.

From 2001 to 2002, she worked as Chief Financial Officer for Long Island Power Authority.
From 2003 to 2007, Taylor served as New York State superintendent of banks under Gov. George Pataki.
In 2010, she considered running for NY Senate against Sen. Kirsten Gillibrand but ultimately decided not to run since, at the time, her boyfriend Mike Bloomberg was serving his third term as NYC mayor. ”It was not the right time for me,” Taylor said.
On March 13, 2010, The Village Voice reported her statement, in which she said she was flattered, “but I have no intention of running for the U.S. Senate.”
From 2014 to 2018, she was Vice-Chair of Solera Capital LLC.
In 2020, Taylor became Director of Citibank, N.A.
Chair of the ballet at 66
September 1, 2021: New York City Ballet made Taylor chair of its board, the first woman in that seat, after Charles W. Scharf, who had the job since 2017.
She did not expect the call. “I practically fell off my chair and said, Well, why me?” she told the Times in 2021.
Katherine Brown, NYCB’s executive director, said in the 2021 release: “The New York City Ballet community could not be more thrilled to welcome Diana Taylor as our next Board Chair.”
Husband
In 1987, Diana Taylor married doctor Jefferson Katims.
Diana and Jefferson divorced six years later and had no children.
”I never had kids because there was never anyone I wanted to have kids with,” she said in an interview.

Second Marriage
Update: in November 2026, Michael Bloomberg married Diana Taylor in a private N.Y.C. wedding.
Diana Taylor is married with Michael Bloomberg, an American businessman and politician who was the Mayor of New York City from 2002 to 2013.

She acted as the de facto first lady of New York City during Mr. Bloomberg’s three-term tenure as mayor.
The two first met in 2000 at a Citizens Budget Commission event.
That first meeting ended with an invitation.
Taylor described it to The Washington Post: “He looked at me and came over and said, ‘Would you like to have a drink after this?'”
She said yes. At the time he was a Democrat and she was a Republican.
Twenty years on, in his 2020 presidential run, labels were still a problem. “I hate ‘girlfriend’ because it sounds so temporary,” she told the Post, and in the next breath: “It’s very junior high.”
Her preferred label was stranger and better: “I’m a unicorn in a unicorn campaign.”
Diana campaigned with Bloomberg during the 2020 Democratic Party presidential primaries in Alabama, Arkansas, Utah, and California.
”He is a man of incredible capabilities and resources,” Taylor said about Bloomberg. She added: ”I’ve always thought that he’d be a really good president.”
Bloomberg has two daughters (Georgina and Emma) from a previous marriage with Susan Elizabeth Barbara Brown. About Bloomberg’s daughters, Georgina and Emma, she called herself “sort of a step-whatever for Mike’s children, friend, I guess.”
