About Us

Atlas Unbound creates immersive experiences that inspire the discovery of hidden lands and plunge participants into the wilderness, learning and innovating from the wisdom of nature. We catalyze transformative conversations and fresh perspectives relating to systems change, leadership models and regenerative cultures. Unfolding the planet has a lot to do with unraveling yourself too, embracing new paradigms and connecting to global challenges through embodied experiences. 

Atlas Unbound was founded by Siobhan Brewster and Alexa Firmenich. 

Siobhan Brewster has previously used an anthropology major, a stint in the fashion industry and five years in international investment banking as her ticket to traversing the world on various adventures. Scottish by birth, her prior chapters have included London, Bali, New York and most recently, four years in Mexico City.

Alexa Firmenich is passionate about designing deep regenerative systems change through the power of transformative experiences and reconnecting with the wild. Her work as a conservation leader, communicator and photographer has taken her around the world. She lives to embrace the thrill of the unknown.

What they say about us... 

What Atlas Unbound has created is nothing short of remarkable. In our crazy, disconnected and repetitive world, a trip into the unknown exploring cultures, communities and creatures provided me with a renewed sense of purpose and a richer perspective on our place in the world. With new friends gained, knowledge shared and a life time supply of stories to tell, this is a winning combination. I would do it again in an instant.

One of the most formative, powerful, genuine and inspiring experiences of my life.

The journey left me feeling breathless and inspired; it felt like I took ten days off instead of a weekend and was left energized for weeks. Reminiscent of a Tarantino film set amongst Mayan temples, the places we visited were so secretly marvelous and the group was filled without exception with such wonderful people that surely will become part of my community.

I loved every step of the journey. Being immersed in the wonders of nature. Personal reflection. Mindfulness. Kindness. Understanding. Mind-expanding conversations with remarkable people from all over the world. Atlas Unbound is that and so much more.
