Center Leadership

Patrick McLaughlin
Chief Executive Officer
Patrick McLaughlin graduated with a degree in Business Administration from the University of Texas-Austin in 1999. Patrick’s entry into the clinical research space was in 1996, when he was recruited to a full-service, multi-specialty dedicated research site, as President. Three years into the position at the Institute of Clinical Research (ICR), sales were up 600% and the ownership group desired to sell the company.
In March of 1999, Patrick was the principal negotiator in arranging a deal that sold ICR to Protocare, a Site Management Organization. Protocare named ICR as one of their premier sites in Centerwatch and one in which other Protocare sites would be modeled after. Shortly after the sale, Protocare was acquired by Radiant Research and ICR to this day is one of Radiant’s leading sites nearly 23 years after its acquisition.
In May of 1999, Patrick started working at Advanced Clinical Research Institute in Anaheim, CA as its Executive Director. Patrick made a decision for the company to enter the Phase I sector after an entire history of exclusively conducting Phase II-IV studies at the facility. Dr. Dennis Riff and Patrick McLaughlin funded the purchase of an 8,800 square foot, dedicated Phase I facility in 2007, and re-branded the company as Anaheim Clinical Trials.
Through years of continued success and the need for additional investment to move the company to the next level and to a much larger state-of-the-art research facility, a decision was made to bring on an additional investment partner which was completed in February 2019. Patrick is now CEO of CenExel ACT.
