Meet the NPA Team

Everyone on our team is passionate about the Psychedelic-Assisted Care (PAC) community and dedicated to supporting this industry.


Founded in 2019, we’ve already come a long way. The team has grown, and we are well set up to serve the needs of this great industry. Thank you for taking an interest in getting to know us. We look forward to meeting with you too.

We began as a non-profit 501(c)(3) organization supporting advocacy work for the industry and a state-specific membership association.

We expanded into a services business supporting the Psychedelic-Assisted Care (PAC) community of clinics and practitioners.

We’re a team of passionate and dedicated individuals, steeped in experience from advocacy to healthcare operations. We’re already working hard to support the Psychedelic-Assisted Care (PAC) community … and we are only just getting started.
