Alexandra Mushin Gericke Sensei was born and grew up in Southern Germany. She skied for the German national youth team, earning her a scholarship for the University of Utah. While coming to Salt Lake City to study Psychology in 1994, she also had her first encounter with Zen practice at the Kanzeon Zen Center.

Wanting to study with her teacher, Soten Genpo Roshi, she became a resident Kanzeon in 1996. Living there for eight years, she trained in both the more traditional forms of Zen as well as in Roshi's Big Mind process. She received Shukke Tokudo (Ordination) in 1998 and served as Roshi's attendant for many years, becoming Hoshi (Lineage Holder) in 2002 and receiving Denkai in 2006.

Since 2008, she has been married to Belgian Zen teacher Frank De Waele Roshi. They live in Ghent with their two daughters. She also trained in body awareness practices like Feldenkrais and Focusing and is working as a certified Iyengar Yoga teacher.

In August of 2022, Mushin received Shiho (Dharma Transmission) from Genpo Roshi in Germany and then went on to start the No Mind Zendo in Belgium.
