Vizient CEO Curt Nonomaque will retire in March and be replaced by the group purchasing organization's chief administrative and financial officer, Byron Jobe, the company announced Tuesday.
During his 15-year tenure at the helm, Nonomaque helped Irving, Texas-based Vizient grow into the largest GPO in the country, now serving more than 3,100 health systems. He was CEO of predecessor company VHA from 2003 to 2015.
Nonomaque, who was selected as one of Modern Healthcare's 100 Most Influential People in Healthcare this year, was a key player in forming Vizient through VHA's 2015 merger with University HealthSystem Consortium and Novation.
His successor, Jobe, will be a good fit for the role after shaping Vizient's strategic, operational and financial direction, according to David Blom, CEO of OhioHealth and chairman of Vizient's board.
"He brings deep experience and a strong skill set to the job, having led complex financial and growth-related endeavors for the company," Blom said in a statement.
Jobe first joined Vizient, then named VHA, in 1994 to tackle corporate planning and business development and left in 1999 to work in the healthcare technology sector for companies including PricewaterhouseCoopers, Baylor Scott & White and Healthvision. He returned to the company in 2007 and helped guide it through the 2016 acquisition of MedAssets' spend and clinical resource management businesses.
Vizient now represents more than 50% of the nation's acute-care providers and more than 20% of the ambulatory-care market.
"Byron is the right person to lead Vizient into the future," Nonomaque said in a statement, "He has extensive experience across all our business lines and has a relentless focus on driving member and company value.
