"about", cesletter.org, accessed Feburary 2, 2023
Born and raised in Southern California, Jeremy is a seventh generation Mormon of Pioneer heritage who reached every Mormon youth milestone. An Eagle Scout, Returned Missionary, BYU alumnus, Jeremy was married in the San Diego Temple with expectations and plans of living Mormonism for the rest of his life.
In February 2012, Jeremy experienced an awakening to the LDS Church's truth crisis, which subsequently led to a faith transition that summer. In the spring of 2013, Jeremy was approached and asked by a CES Director to share his questions and concerns about the LDS Church's origins, history, and current practices. In response, Jeremy wrote what later became publicly known as the CES Letter (originally titled Letter to a CES Director).
The CES Director responded that he read the "very well written" letter and that he would provide Jeremy with a response. No response ever came.
