Quest Diagnostics: Yuri Fesko

Quest Diagnostics has named Yuri Fesko senior VP and chief medical officer. He replaces Jay Wohlgemuth, who held the role until he stepped down in early 2023. Fesko has served in a number of roles at Quest since joining the company in 2016, most recently as VP of medical affairs and senior medical director for oncology services. Among other achievements, he led the clinical development of the company's 500-gene somatic tumor NGS panel, as well as clinical research on minimal residual disease test technology developed by Haystack Oncology, which Quest acquired earlier this year. Prior to joining Quest, he was medical director of oncology for the Duke Cancer Center and chief of oncology for Wake County in North Carolina. Fesko holds MD and bachelor's degrees from Case Western Reserve University.
