He has studied and trained in the Mahayana Buddhist tradition since 1995, most intensively with Geshe Michael Roach. He is a certified ACI teacher and has taught internationally since 2006. David and Sarahni helped establish the Diamond Mountain Retreat Center in southeastern Arizona, where he served as operations manager from 2004 to 2010.
From December 2010 to April 2014, he and his lovely wife participated in a three-year, silent, isolated retreat at Diamond Mountain Retreat Center. During the three-year retreat he received a transmission for the practice of White Tara, which is now his main personal practice. During retreat, he wrote a compendium of advices on her practice, which he enjoys sharing with those who feel connected to White Tara. He is currently teaching students in South Africa.
