Patient Square Capital, a healthcare investment firm headquartered in Menlo Park, Calif., has added John Marotta as executive in residence with the firm.

In this role, Marotta will leverage his decades of operating and leadership experience in healthcare to pursue investments in life science tools and diagnostics companies. He recently served as the president and chief executive officer of PHC Holdings Corp., a global life sciences, diagnostics and medical device company formerly known as Panasonic Healthcare. Prior to that, he was president and CEO of Epredia. Marotta led PHC Holdings to an initial public offering, where he helped to deliver growth, drive operational improvements, expand margins and complete the carve-outs of Epredia & LSIM from ThermoFisher and Mitsubishi respectively.

“We have identified the life science tools and diagnostic sector as an area primed for innovation and operational efficiency and believe John can play an instrumental role in helping unlock that potential,” comments Jim Momtazee, managing partner of Patient Square.
