Perspectives from Our Faculty

"The brain-reset analogy makes people think psychedelic-assisted therapy is a passive thing. In fact, it is a deeply engaged process that requires support from trained therapists."

Rosalind Watts, PsyD

"The work of a therapist is to be confronted with difficult situations every day. Finding a place where you are taken care of as a therapist can be very helpful."​

Marc Aixalà, MSc​
