Shindō Jim Nowik started on his dharma path with an introduction to Zen at Zen Mountain Monastery in Mount Tremper, New York, in the early 1980s. After years of dabbling in the Dharma, he became a formal student of Helen Kobai Yuho Harkaspi, sitting regularly with her practice group in Poughkeepsie, New York. After he showed interest in a more disciplined practice, Helen introduced him to Stef Mui Barragato at Dragon Cliff Zen Center in Kerhonkson, New York, where he received jukai in 1997 and shukke tokudo in 1998. He practiced there for 12 years, focusing on koan study. He also served for years as an assistant Buddhist chaplain at the Eastern NY Correctional Facility, a maximum-security prison in Napanoch, New York.
When Stef moved to Maine to start Treetop Zen Center, Jim began practice at Valley Zendo in Charlemont, Massachusetts, a Soto branch temple of Antaiji under the direction of Isshō Fujita, focusing on shikantaza. Though never a formal student of Isshō’s, Jim considers him an important mentor.
Jim spent several years in the interim sitting with different teachers before beginning a residency at Treetop in 2016. He continued his formal practice there with Peter Joryu Harris, receiving denkai and dharma transmission in 2018. He now serves Treetop as a senior priest and teacher in residence. He also serves as a Zen Buddhist instructor at Colby College in Waterville, Maine.
Previously Jim practiced anesthesia as a nurse anesthetist in New York City for more than 25 years. He has two grown children, Kailen and Dylan, and one granddaughter, Claire.

He sat with a lay Zen group in the DC area but did not begin formal practice with a teacher until he moved to Maine in 2016.
Prior to coming to Maine, Brad worked as a hospice chaplain and pastoral counselor in the regional Washington, DC, area, where his patients and families taught him the practice of spiritual care at end of life and deepened his experience of and commitment to the interfaith path of many threads, one heart.
