Quest Diagnostics to Promote Exec VP James E. Davis to CEO

Quest Diagnostics has appointed its exec VP of general diagnostics James E. Davis to be the company’s next CEO, effective November 1. Davis will succeed Steve Rusckowski, who will have been CEO for over a decade. Rusckowski will continue to serve as Quest’s Executive Chairman through March 2023.
 
“Today, Quest is the clear leader in diagnostic information services, positioned for continued execution of its ambitious growth plans under a new CEO in Jim Davis, who has been instrumental in accelerating growth and driving the company’s operational excellence program for eight years,” Tim Ring, Quest’s Lead Independent Director told the press. “Jim is uniquely qualified to lead Quest in its next phase of growth, and this gradual and comprehensive transition process will ensure continuity for the company’s strong market momentum.”
 
Davis, 59, currently oversees Quest’s diagnostics business, which accounts for over 80 perfect of the company’s $10.8 billion 2021 revenue. He joined Quest in April 2013 as senior VP of diagnostic solutions, named senior VP of operations in February 2014, and finally his current position in 2017.
 
Further, he has provided oversight for the company’s pandemic response, overseeing rapid molecular testing capacity development and expansion. His team innovated new testing techniques and new models for patient testing, including retail sites and direct-to-consumer testing.
 
“I am deeply honored to have the opportunity to succeed Steve and lead Quest into the next phase of growth and build on our vision of empowering better health with diagnostic insights,” said Davis. “Our company has never been more integral to patients and the healthcare system, as we have seen during the pandemic. Together with the Quest management team and all 50,000 of our colleagues, I look forward to building on the strong foundation we have put in place. Quest’s future is bright, and we are extremely well positioned to continue to create value for shareholders as well as all the patients, customers and partners we serve.”
 
Mark Guinan, executive VP and CFO also announced his intent to retire this year following eight and a half years in his role. The process to identify a new CFO has begun.
 
Current Quest CEO Rusckowski said, “I want to thank Mark Guinan for his many contributions as a key member of our leadership team as we have transformed Quest and accelerated its growth. I am especially grateful that Mark has remained central to our team throughout the pandemic, and that he will ensure that the transition to his successor is seamless.”
