Michael Lewis has been selected to be the next Putnam County commissioner of finance by County Executive Kevin Byrne, taking over for longtime Commissioner Bill Carlin, who recently retired. Lewis has been serving as chief deputy finance commissioner since 2021.
The appointment is contingent upon approval by the County Legislature.
“Mike Lewis brings a dedication to fiscal responsibility that is desperately needed to ensure the continued effective financial operation and management of our taxpayer dollars,” said Byrne. “I am confident in his ability to effectively manage the county’s finances, promote fiscal responsibility, and drive economic growth in our community.”
Lewis was appointed by the county executive after a “competitive interview process” was conducted by a selection committee.

Carlin said he is proud of Lewis and of the work they did together over the last couple of years. “I’m confident the county is in good hands with County Executive Byrne and Commissioner Lewis,” he said. “It’s been an honor to serve the residents of Putnam County for the past 30 years.”
While Carlin has officially retired, he has agreed to stay on through the rest of 2023 in an advisory role to the administration, at minimal expense to taxpayers. Carlin will assist the county in navigating its first budget without him at the head for nearly 34 years.
Lewis is a native of Putnam County, having graduated from Mahopac High School before earning a bachelor’s of business administration degree in accounting from Pace University.
He collectively worked more than 10 years as a private sector accountant and auditor at KPMG and PKF O’Connor Davies, and more than 11 years in government finance, having served as deputy commissioner of finance/treasurer for the City of New Rochelle and chief deputy commissioner of finance in Putnam.
