Sarah London has gotten the nod for the CEO role at Centene Corporation following news that retiring CEO Michael Neidorff would be stepping away early due to a medical leave of absence.

The Harvard College and University of Chicago Booth graduate has been with the company since 2020, serving as its senior vice president of technology innovation and modernization.

More recently, she served as Centene’s vice chairman of the board, responsible for managing a portfolio of non-health plan companies, designing differentiated platform capabilities and delivering products and services to customers, according to the announcement.

Prior to joining up, London served as a venture capital partner at UnitedHealth Group’s Optum Ventures, chief product officer for Optum Analytics and the vice president of client services and operations at Optum-acquired healthcare data and analytics firm Humedica. She also held roles at Accretive Health and Health Leads.

London’s appointment is effective immediately. Neidorff remains on leave from his remaining position on Centene’s board.

Toyin Ajayi, M.D., has added the title of CEO to her roles as president and co-founder of Cityblock Health, the disparity-focused healthcare company.

Iyah Romm, Cityblock’s other co-founder and prior CEO, had announced in November a leave of absence to focus on his mental health and handed former federal policymaker Andy Slavitt the reins temporarily. Romm will remain a member of Cityblock’s board.

Ajayi is a practicing family medicine doctor who had served as chief medical officer of integrated health plan and care delivery system Commonwealth Care Alliance prior to launching Cityblock out of Alphabet’s Sidewalk Labs in 2017.

The upgraded role will see Ajayi homing in on scaling her company as it aims to provide healthcare and social services to Medicaid, dually-eligible and lower-income Medicare beneficiaries in new markets.

Robert Wieland, M.D., has been promoted from his role as chief medical officer to CEO of Allina Health | Aetna, effective immediately.

He’s been a part of the provider and payer’s joint venture health plan since its 2017 launch and before that was chief strategy officer at Allina Health itself. His time with the system also placed him in charge of its integrated medical network as well as its clinics and community division.

Wieland will remain in charge of the plan’s care and medical management strategy as well as the formulation of its standards of care. Moving forward, he will also be overseeing the plan’s executive leadership, setting strategic direction for its Medicare and commercial segments and guide its continued growth, according to the announcement.

Wieland is now reporting to the Allina Health | Aetna board of directors. Tom Lindquist had previously filled the CEO role.

Miruna Sasu has been tapped as the new CEO and president of COTA, a provider of oncology real-world data abstraction, curation and analytics for healthcare providers and life sciences companies.

The pharma industry vet joined COTA last year as its chief strategy officer following a two-year stint at Johnson & Johnson as head of clinical trial feasibility and data science.

Prior to that, Sasu was with Bristol Myers Squibb for five years as a manager, associate director and finally head of innovation and digital health. She also served as a branch chief at the U.S. Department of Agriculture’s Food Safety and Inspection Service.

Sasu takes on the new role with growth in mind, particularly around the company’s efforts to build up strategic partnerships with providers and clinical research groups targeting cancer breakthroughs. She also said she is interested in expanding the company’s work to promote clinical trial diversity using its real-world data.
