About Our Founder

Marissa Feinberg is the founder of Psychedelics for Climate Action (PSYCA), a growing community of 13,000 people committed to raising and expanding consciousness to discover pathways through the climate crisis. Evolving her focus from social and environmental impact to psychedelics in recent years, Marissa began convening communities at the intersection of climate and consciousness in 2023. Her spark moment came from a regenerative agriculture client, who reminded her: “Environmental problems are human problems—it’s the humans who are destroying the planet.”

Marissa is now on a mission to convene the PSYCA community globally, uniting leaders and enthusiasts across climate and psychedelics to transform the climate crisis into a consciousness opportunity. By bridging these ecosystems and cultivating a mycelial container for unconventional solutions — both consumer-facing and systemic — and initiatives that drive these approaches forward, she and the PSYCA community believe that, together, we can uncover pathways through the climate crisis and meet this era of unprecedented global transformation with psychedelic values of oneness, interconnectedness, and compassion.

In service of this mission, since founding PSYCA, Marissa has helped the movement gain momentum with nearly 100 earned media stories since January 2024 alone. She spoke at SXSW 2025 on "How Psychedelics Can Accelerate Climate Action" and hosted the Changemaker Discussion at The New York Times' Climate Forward 2024, "Can Psychedelics Help Address Climate Change?" during Climate Week NYC.

In parallel, Marissa leads Triple Bottom Why, a boutique communications consultancy and thought leadership advisory for values-aligned organizations. She created the “triple bottom why”™ method to align clients’ internal purpose with their audience and business goals—supporting people, planet, and profit through storytelling. Her clients span industries from regenerative agriculture to psychedelic therapy and have been featured in The New York Times, TechCrunch, Mashable, BBC World, Bloomberg, Fast Company, Entrepreneur, Inc., Forbes, and NBC, among many others.

Marissa entered the psychedelic therapy space as fractional PR & Brand Director for Nushama Psychedelic Wellness, helping the organization grow from inception into the nation’s leading ketamine therapy brand within two years. Helping build the global ketamine therapy narrative, educating consumers and the media, she guided the strategy and execution to earn over 200 press stories, including feature stories in The New York Times, Good Morning America and The Wall Street Journal.

Previously, Marissa co-founded Green Spaces NY, the first coworking and events space in New York City for environmental and social entrepreneurs, creating a working home for them to convene, learn, grow and thrive. It was acquired and became part of the global Impact Hub network, where she later served as Vice President of Marketing + PR for its parent company, MissionHUB, and its flagship event, the SOCAP Conference for impact investors.

Her pioneering work in the coworking and climate space earned her organization recognition in The New York Times, Gotham Magazine’s “The List” and profiles in Mashable, Crain’s, and Triple Pundit, among others. She has also written for Forbes, featuring many of the mission-driven entrepreneurs and organizations she has supported, supporting their education and awareness efforts.

Marissa frequently speaks on topics ranging from psychedelics and climate to leadership, impact, and storytelling. She has recently presented at SXSW, The New York Times Climate Forward, Psychedelics as Medicine Iceland, Transformative Impact Summit, Harvard University’s Climate Leaders Program, Psychedelic Humanities Lab, and for Social Venture Circle, NYU Entrepreneurial Institute, and more.

She also supports Connected Leadership, a pioneering psychedelic leadership and creativity program developed by regenerative economics professors and studied in partnership with the University of Maryland, as featured in The New York Times' “The C.E.O.s Are Tripping. Can Psychedelics Help the C-Suite?”

A graduate of Syracuse University’s S.I. Newhouse School of Public Communications, Marissa earned her degree in Public Relations with a Marketing minor from the Maxwell School of Management. She serves on the boards and advisories of Green Map, The Predistribution Initiative, Ecodeo, Entertainment for Change, and The Artist Co-op.
