Small Group Retreats
A deeper connection to the beginning of your story
Our 3-day retreats
At the Experiential Training Institute, our small group retreats are the heart of our work.
These 3-day retreats (maximum 8 participants) are designed for people who want to explore their inner world within a carefully held, relational container — supported by experienced facilitators and the quiet presence of others doing their own work. Rather than working in isolation, the group offers pacing, grounding, and a sense of shared humanity that many people find deeply regulating and unexpectedly supportive.
People often come to our retreats feeling curious, stuck, disconnected, or quietly searching — for clarity, meaning, creativity, or a deeper relationship with themselves and others. The retreat creates space for this exploration to unfold gently, without pressure to perform, fix, or force insight.

Compassionate care
What you might experience
New perspectives from a different angle on the same issues that you have struggled with, enabling you to experience a new way of thinking
Processing of childhood memories that have impacted your life, allowing you to shine a new light on feelings of vulnerability, internalised shame or guilt and increase self-acceptance
Increased self awareness and self-love, which can result in a renewed sense of being and belonging
Emotional release; positively altering your emotional process in two ways: increasing your ability to be in direct contact with the present moment and enhancing experiences of positive emotions enabling you to experience a new way of thinking.
The ability to feel a deep and profound sense of connection to yourself (or the different parts of you), to others and to the environment, which encourages you to keep your heart open and develop stronger relationships with others
Structural neural plasticity (the brain’s ability to make new connections) has been understood to provide some of the greatest benefits, which can lead to an overall increase in the adoption of new behaviors and positive habits
