About Mary Beth Leisen, PhD and the Yellow Arrow Collective

How the Yellow Arrow Collective Was Born
I’m Mary Beth Leisen, PhD, founder of the Yellow Arrow Collective. I’d been working an unfulfilling job and was aching to move somewhere I could hike and be outdoors. In 2018, I walked the Camino de Santiago, a 870km pilgrimage across the entire country of Spain. We were guided by ubiquitous yellow arrows that kept pilgrims on the path and encouraged us all to move courageously ever onward, as a community.
The Camino changed my life, and it is the spirit of the Yellow Arrow Collective: people coming together to support and encourage each other in taking courageous steps to transform our lives, in small and big ways.
My personal healing journey and calling to serve others have both been lifelong. I’ve struggled with being adopted, interpersonal traumas, divorce, grief, and depression – and with a very active chorus of inner critics, judges, and mind hijackers inside my head. I’ve also been incredibly blessed with family, friends, therapists, teachers, coaches, and mentors who have been there for me and with me along the way. The path of healing and growth is not always easy, but it is deeply rewarding. I’m proud to be a lifelong work-in-progress, and I hope you are, too.
I firmly believe that to thrive, we need to attend to our well-being holistically: mind, body, and soul (however you define your most innate, wise, connected self). We need to be in right relationship within ourselves (living our values, intention, and purpose), with others (respect,integrity, harmony), and with the world (in communion with nature and energy). In this epidemic of loneliness, I believe we are all hungering to have more meaning, to truly connect and belong, and to remember and embody our wholeness – our innate goodness that has never been broken or in need of fixing but that expresses who we truly are in our healthiest, most healed state. Ceremony, nature, and my beloved communities help me continue to foster this kind of growth.

Mary Beth in Boulder – and the World
Last but not least, I’d rather be on a hiking trail, traveling, or eating a delicious meal than doing anything else – especially if it’s with my amazing husband, Mark. I’ve visited over 50 countries and also love to cook, read, bike, photograph, write, knit, play, connect with nature, and be in ceremony. Growth, curiosity, and openness are the keys to a meaningful and fulfilling life, and in the spirit of my Second City training, I’m committed to living a “Yes, and” life with as much energy, laughter, and joy as possible.
