DocGo Chief Executive Lee Bienstock is standing by the mobile-healthcare company’s performance under a controversial migrant-care contract awarded by New York City.

In an interview, the former Google executive, who took the reins of DocGo in September, defended the company’s work serving the tens of thousands of asylum-seeking migrants in New York. He said the work fits into DocGo’s mission to provide healthcare in homes and other settings beyond traditional hospitals and healthcare facilities.
