Prior to joining Ridgewood in 2000, Warren held executive positions at various venture-backed companies and led the turnaround of a public company and its subsequent merger. Warren spent the first segment of his career building Corning Corporation’s diagnostic subsidiary to be what was and still is, the world’s largest clinical laboratory, now known as Quest Diagnostics. This business grew annual revenue from $90 million to over $500 million during his six-year tenure.

Subsequently, Warren co-founded LifePoint Corporation, a successful regional competitor to Quest Diagnostics. As the CIO for Medical Resources, the nation’s largest diagnostic imaging enterprise, Warren brought over 100 imaging sites onto one information system and managed its software subsidiary. As the CEO of Princeton Diagnostic, a publicly traded AMEX company, Warren led a financial turnaround and profitable sale of the business. Warren joined Ridgewood Capital in 2000 as its Chief Financial Officer and transitioned to a Managing Director investment role.

Warren received his MBA from Cornell University Johnson Graduate School of Management and his BA from Michigan State University. He is responsible for the investments in Volterra (IPO in July 2004), Bluesocket, Comverge and Oryxe-Energy.
