Jeffrey E. Poehlmann is a writer and filmmaker based in Los Angeles. After a mass was discovered in an X-ray following his treatment for a torn rotator cuff, it took nearly three months to receive a final diagnosis. He began chemotherapy toward the end of 2014 and completed 40 rounds in August 2017. He is in a clinical trial for a targeted drug designed for a mutation that was not treatable four years ago.
