In 2010, Rohrer and six other Bay Area gay and transgender pastors were reinstated into the Evangelical Lutheran Church in America, after the national assembly voted to allow partnered gay people to serve as clergy. When the policy changed in 2009, Rohrer became the first openly transgender person to serve as a minister in the Evangelical Lutheran Church in America. Rohrer was ordained in 2006, during a time when the ELCA did not allow LGBTQ pastors to openly serve.

Rohrer claims to be related to Nicholas of Flüe in the 16th generation.

Rohrer attended Pacific Lutheran Theological Seminary before transferring to the Pacific School of Religion (PSR) in Berkeley, California, earning a Master of Divinity degree from PSR in 2005 and a Doctor of Ministry degree in 2016. By this time they had come to identify as transgender. Rohrer moved to the San Francisco Bay Area in 2002 to continue their studies. They encountered resistance, threats, and attempted 'cures' by fellow students for their sexuality. In college they came out as gay, and became president of the gay–straight alliance. In 1998, they graduated from high school and enrolled at Augustana University to study religion. Rohrer was born on April 3, 1980, in Sioux Falls, South Dakota. Following their reception as a minister in the Evangelical Lutheran Church in America, Rohrer served the church as bishop of its Sierra Pacific Synod from 2021 until asked to resign in June of 2022 after allegations of racism against one of the pastors under their care came to light. Rohrer was the first openly transgender minister ordained in the Lutheran tradition. Megan Rohrer (born 1980) is an American Lutheran minister and activist.
