What people say about Sean:

"Very informative and delivered very well. Interactive session. Helpful to our role as AMHPS.  Enabled me to stop and think about my own assessments and how to help others."

"Good to have some organic conversations that were meaningful rather than the usual just for the sake of it. The day went very quickly which is a good sign! Useful to see photos of drugs in various states. Harm reduction advice excellent."

"Really nice relaxed manner. Allowing sharing of experiences and good conversations"

"The trainer was very knowledgeable and kept the group engaged throughout. He adapted the course to our learning needs. It was a very enjoyable session!"

"Every aspect was really helpful. Could easily be a 2 day course. Really sensitively delivered without judgement."

"Very approachable, easy to engage and a good balance of stats/law/knowledge."

"Really well delivered course. It's always so much better having a practicing AMHP teaching us!"
