Nystrom & Associates, a Nautic Partners-backed group of professional care providers in psychiatry, psychology, clinical social work, marriage and family therapy, substance use disorder and nursing, has named Mark Peterson as its new CEO. Peterson succeeds Mark Arnold who has held the role since May of 2020.

Peterson most recently served on Nystrom’s board of directors. Prior to that, he was the CEO of Genoa Healthcare. While at Genora, Peterson grew the business from a startup, generating over $3 billion in revenue. During his tenure, the organization also achieved a medication adherence rate of over 90 percent, demonstrating a commitment to quality of care. He also broadened Genoa’s service offering, adding telepsychiatry in 2015.

“With more than 20 years of experience in behavioral health and an ongoing dedication to the Nystrom organization, we are excited that Mark will lead the company in its next chapter of growth and expansion,” says Brian Nystrom, founder and current board member of Nystrom.
