Mary Beth Leisen, PhD

Founder and Principal, Yellow Arrow Collective

Mary Beth Leisen, PhD is a clinical psychologist, coach, and mentor who creates and delivers programs online and in-person: courses, talks, workshops, and retreats.  Mary Beth's programs are based on her training background across a variety of areas, from science to spirituality: neuroscience / neurobiology, psychology, mindfulness, compassion, skill-building, Eastern philosophy, and indigenous wisdom practices.  Mary Beth's psychology background focused on understanding and treating stress, anxiety, PTSD, and depression in adolescents and adults.  She has led workshops, trainings, and other programs in over 25 cities across four continents.

 Mary Beth lives in Boulder, CO and would rather be on a hiking trail than just about anywhere else.  In 2018, she walked across the country of Spain on the Camino de Santiago, which inspired the name and philosophy of the Yellow Arrow Collective, which you can read more about here.  She believes that the most powerful growth and healing for the mind, body, and soul take place in deep connection with others and with the natural world, and she does coaching, retreats, and ceremony in nature as much as possible.  

Mary Beth has traveled to over 50 countries and dreams of seeing all of them.  She views a commitment to growth, curiosity, and openness as the key to a meaningful and fulfilling life, and in the spirit of her yearlong training at The Second City, she's committed to living a “Yes, and” life with energy, laughter, and joy.
