Corbin Petro, founder and CEO of hybrid substance use disorder (SUD) provider Eleanor Health, announced her plans to resign.

She said she intends to remain on the company’s board and take a more strategic role in the future.

“As I look at where I can be most valuable to Eleanor during this next phase of growth, it’s in a more strategic role,” Petro wrote in a Linkedin post. “With the board’s support, I have made the decision to transition out of day-to-day CEO duties and into the role of board member and advisor. I’m looking forward to continuing to support the important work Eleanor does, including helping in the search for a new CEO.”

In the meantime, the company has formed the Office of the CEO, which Kyle Raffaniello, one of Eleanor’s independent board members, will lead. Raffaniello is the CEO of the predictive health care analytics company Prealize Health.

Waltham, Massachusett-based Eleanor is focused on providing addiction and mental health care on value-based payment models. The company has garnered a fair amount of investor attention. In 2022, it raised $50 million in Series C funding, bringing its total raise to roughly $82 million.

Eleanor offers virtual or in-person treatment in Massachusetts and medication-assisted treatment. It accepts several insurance plans, including UnitedHealthcare, Horizon, Aetna and Tricare.

“I don’t make this decision lightly – I love this company, I love this team, I love our mission,” Petero wrote. “However, as a board member and advisor, I will be close and will continue to help shape our future and vision.”

Behavioral Health Business reached out to Eleanor Health for comment.

Under Petro’s leadership, Eleanor has made several deals with payer organizations. For example, in 2021, Eleanor inked a partnership agreement with health plan Point32Health to develop a value-based program built on a population health model to provide care to serve its Medicaid members.

In 2022, Eleanor Health announced a value-based care partnership with managed care organization Amerigroup Washington to provide care to its members living with SUD. The agreement aimed to reduce the total cost of care and improve key outcome metrics.

This isn’t the first C-suite shakeup for the virtual SUD provider. In November, Eleanor announced a new chief customer and patient engagement officer, chief financial officer and chief of staff.

And it hasn’t been all smooth sailing for Eleanor. Late last year, the provider reduced staff by roughly 18% to 20%.
