About Mark: As the CEO and co-founder of SonderMind, I lead a fast-growing and compassionate team whose mission is to redesign behavioral health to increase access, expand utilization and improve clinical outcomes. Our focus is to democratize behavioral healthcare for both patients and practitioners, by making it easy to access therapists with the right expertise, making it convenient by offering online or in person treatment, and making it affordable by matching patients with highly qualified providers that deliver the most effective care. I believe in leading with transparency, empathy, and courage, and my passion is to build an organization that has a positive and transformative effect on the field of behavioral health and ultimately the entire healthcare ecosystem. Prior to founding SonderMind in 2015, I helped found three other successful ventures, including Next Oncology, TermScout and SafeImageMD. Prior to my career as an entrepreneur, I worked in healthcare investment banking at Morgan Stanley, as well as time with Lehman Brothers and CDI Global. Prior to my business career, I served as an officer in the US Army. During and after that time in the military, I saw friends and colleagues return from deployments and struggle to access appropriate mental health care. This experience shaped and strengthened my commitment to enhancing access to therapy to improve and enrich people’s lives.

Why CEOs keep coming back.
01
A room that gets it
Every attendee is vetted. No service providers, no job-seekers. CEOs are peers, not products. One room, 40 CEOs, one evening a month.
02
Structured to connect
Not a mixer. Before each dinner, everyone gets the full list of attendees and their asks. Introductions are built in. There’s always a speaker. The right conversations happen by design.
03
More than a dinner
Between events, members keep showing up — making intros, answering questions, helping each other. You’re not attending an event. You’re joining a community.
Scenes from the last three years.
“We start companies because we can’t help ourselves. The smart founders find a room full of people who are just as crazy and want to help.”
— Eric Marcoullier, Founding Director
