Struggling with PTSD, addiction or recovery?
A Guided Retreat in Colorado
A small, guided three-day retreat in Boulder, Colorado with Maureen Lennon-Schafer. Dates run from October to February: tell us you are interested and Maureen will be in touch personally.
January 8 to 10, 2027 · Boulder, Colorado

A few days away with a small group and an experienced guide: quiet mornings, time outdoors, circles that are small enough for everyone to be heard, and real time to rest.
Maureen speaks with everyone before they join. That first conversation is about you: what you are carrying, what you hope for, and whether this retreat is the right fit. There is no obligation.
The retreat runs over three days in Boulder, Colorado. Dates: October 23 to 25, November 6 to 8, November 13 to 15, December 4 to 6, January 8 to 10, January 21 to 24, February 19 to 21 and February 26 to 28. Groups are kept small, so register your interest below and Maureen will help you choose a date.
Who it is for
For adults who are carrying something heavy and want unhurried time away, a small group and an experienced guide. Maureen speaks with everyone first, so you will know whether it is right for you before you commit to anything.
How the days go
A conversation first
Maureen speaks with everyone before they join: what you are carrying, what you hope for, your health and your medications, and whether this retreat is right for you. There is no obligation.
Day one: arriving and preparing
You settle into the house, meet the small group and spend the afternoon in a group preparation session with Maureen.
Day two: the guided session
A long, guided session at a licensed healing center under Colorado's regulated natural medicine program, with facilitators present throughout, then a quiet evening back at the house.
Day three: integration
A group integration session to make sense of what came up, and time to rest before you travel home.
Included
Two nights in a premium house with private or shared rooms, meals prepared by a chef, transport to and from the healing center, and facilitators on site for the whole retreat.
