Honoring Marcus Grail: A Life of Service

On August 22nd, our beloved friend, teacher, and mentor Marcus Grail passed away from complications following a major stroke.

Marcus dedicated his life to healing and service. He was a pioneer in the psychedelic renaissance, developing a groundbreaking 5-MeO-DMT protocol now used worldwide. For more than a decade, he led Mankind Project groups, helping thousands of men find peace and belonging.

He was also an arborist, tending to Northern California’s trees, and an aerobatic flight instructor, teaching pilots to trust themselves and soar. Most of all, Marcus was a devoted husband and father of three, touching lives with his compassion, wisdom, and heart.

In the wake of his passing, his wife Geffen faces profound grief and mounting medical bills. We invite you to join us in lightening this burden in honor of Marcus’s extraordinary life of service.

Every donation, share, and memory matters.
