WE’RE HERE FOR YOU

Prescribed by medical professionals and guided by registered nurses from our secure, HIPAA-compliant telemedicine platform, KetaMD provides safe, effective, and potentially life-changing at-home ketamine treatments for those who are suffering from depression, anxiety, and other mental health challenges.

Our Story

KetaMD was founded by Warren Gumpel and Zappy Zapolin, two pioneers in the psychedelic industry.

For the last decade, Warren and Zappy have dedicated their lives to help those suffering from debilitating mental heath issues find relief through psychedelic medicines.

Having personally experienced the healing benefits of ketamine, they sought out to bring this innovative treatment to those greatly in need through The Ketamine Fund, a non-profit devoted to help veterans and others fighting life-threatening mental health disorders.

Since its founding in 2019, The Ketamine Fund and its founders have donated approximately 500 free and subsidized treatments to veterans and their families.

When the Covid-19 pandemic hit in 2020, access to the in-person ketamine clinics serving this community evaporated. Zappy and Warren knew they had to find another way.

They partnered with Chief Experience Officer and bestselling mindfulness author Kaia Roman, and from there KetaMD was born.
