History[edit] Originally founded as Metropolitan Pathology Laboratory, Inc., in 1967 by Paul A. Brown, MD, the clinical laboratory underwent a variety of rebranding processes. In 1969, the company's name changed to MetPath, Inc. with headquarters in Teaneck, New Jersey. By 1982, MetPath was acquired by what was then known as Corning Glass Works, and subsequently renamed Corning Clinical Laboratories.

Modern day growth[edit] On December 31, 1996, Quest Diagnostics became an independent company as a spin-off from Corning. Kenneth Freeman was appointed as CEO during this transition. Over the next year, Quest acquired a clinical laboratory division of Branford, CT-based Diagnostic Medical Laboratory, Inc. (DML).[5] Two years later in 1999, Quest added SmithKline Beecham Clinical Laboratories to their subsidaries; which includes a joint venture ownership with CompuNet Clinical Laboratory. The new millennium welcomed the launch of Quest's Six Sigma in 2000 - a data-centered approach to process improvement strategy within the healthcare industry. From May 2004-April 2012, Surya Mohapatra, PhD, served as the company's President and CEO. In response to Mohapatra's resignation after 8 years with Quest, former Philips Healthcare CEO Stephen Rusckowski was appointed.[6] Under Rusckowski, Quest Diagnostics bought all the labs, including the business, from UMASS Memorial Hospitals in Worcester, MA.[7]
