      The most amazingly magical and powerful retreat I've ever been on.

    I attended the Evolving Leadership for a New Civilization retreat on Lake Atitlan by Holos Global in Jan 2020. Upon arriving at the agreed-upon hotel in Guatemala City we all caught a shuttle the next morning to Lake Atitlan. Communication was clear and the retreat logistics were well organized. The retreat center, Villa Sumaya, that we had the retreat at was absolutely lovely. The accommodations were clean and comfortable, the art uplifting and healing. The staff was friendly and helpful, the meals absolutely delicious! The temple spaces were stunningly beautiful and well maintained with the most amazing view of the lake and the volcanos. Holos outdid themselves with the choice of location for sure. The ceremonies were deep and profoundly magical for me. I had never experienced that particular type before and it really made me feel connected to my deepest self and to spirit. Both Ian-Michael and Samantha Sweetwater held amazing space during the retreat and made everyone feel safe to be their authentic selves and dig deep into their own truth around leadership. We prayed for our own evolution, for the evolution of humanity and the planet. We called in a new paradigm, the creation of a new civilization that is sustainable and puts the sacredness of life first and foremost. All of us could feel the power of the retreat and the difference it made in our hearts and in our lives. We've made a lifelong connection of friendships and of people who are together committed to making change in the world for the better. I strongly recommend Holos Global and encourage you visionaries, mystics, leaders and conscious entrepreneurs to attend the next leadership for an evolving civilization retreat! Or any of their other retreats. :)

      Unforgettable Experience!

    Ian-Michael Hebert is an amazing leader and heart-centered visionary. The Living Visions Retreat was an unforgettable experience! As the world begins to wake up to the wisdom of plant medicines it's important to have communities like Holos to guide the way. May we all find our way back to our own true nature.

      What an honor

    My experience with Living Visions was incredible. I really felt like everyone participated and contributed in their own beautiful way, which not only brought us closer as a group but also let us each shine. We were also engaged directly in the ceremonies with the elders of the indigenous group we had the great fortune of journeying with and learning from. Overall, it was an experience of a lifetime and I’m so grateful to be involved with such creative and collaborative people.

      A beautiful retreat

    I could not recommend a retreat with Holos enough. The facilitators Samantha and Ian-Micheal picked a beautiful spot to hold the retreat. Along with this, both facilitators were amazing when it came to holding space for experiences ranging from trauma releases to spiritual awakenings. I came back from my time in Guatemala feeling like a new person thanks to this retreat. This was my first retreat with Holos, and it will not be my last.

      Massive heart opening

    My experience in the Holos retreat was life changing. I feel so grateful for the deep guidance and safe loving container that held me through healing waves and allowed me to soften the shields around my heart. I feel more fully opened to life and positive and excited about my future and more confident about my place in the whole as I can now deeply feel and recognize the wholeness and beauty in me. After the Holos retreat, I feel more mental clarity and relaxed in my nervous system as I had just gone through a lot of transition and change shock in the months before the retreat. I now feel grounded and more connected to others and know that the container Ian-Michael and Samantha held allowed for deeper connection to source, my true essence and the others who were there with me. It was such a beautiful, ceremonial experience that I will never forget. I’m so glad I took the leap of faith and gave myself this gift. - Eden
