Karen Mills, head of the Small Business Administration, told agency staff Monday she is stepping down after four years at the helm.
Mills will continue to lead the agency until her successor is named, according to the notice.
She said small businesses have won more than $286.3 million in federal contracts over the last three years of reporting, $32 billion more than the previous three years.
The agency also supported more than $106 billion in loans to more than 193,000 small businesses and entrepreneurs, including two record years of delivering more than $30 billion annually in loan guarantees, she said.
SBA brought more than 1,000 community banks into SBA lending and secured $20 billion commitment from 13 banks to increase their small business lending over three years, Mills said.
