J. Patrick Sheehan, a managing director for public finance at Wells Fargo & Co. in New York and, as a student, the first person to serve as Georgetown University's mascot, in a bulldog costume, has died. He was 54 and was a resident of Larchmont.

He died on Nov. 9 after the chauffeured Lincoln Town Car he was riding in was struck by a Ford Explorer sport-utility vehicle that crossed the median on the Hutchinson River Parkway, according to a police statement.

He died at the scene, as did the driver of his livery car, Ata Noorzi, 51, of Queens.

The Ford also hit a second SUV and both drivers were taken to Jacobi Medical Center and listed in stable condition, police said. The accident is under investigation.

Sheehan, whose 26-year banking career included stints at JPMorgan Chase & Co., Citigroup Inc. and Lehman Brothers Holdings Inc., joined San Francisco-based Wells Fargo in June 2010, specializing in not-for-profit health care clients. He headed the bank's unit serving that industry for the eastern United States. "Sheehan was a trusted senior and experienced adviser to his not-for-profit health-care clients, which included some of the most prestigious hospitals across the country," the bank said in a statement. "His genuine honesty, intellect, expertise and quick wit were highly valued and appreciated by all."

In 1977 as an undergraduate at Georgetown in Washington, Sheehan was the first person to prance the sidelines of sports events dressed as Jack the Bulldog, the school's mascot, according to the university's website.
