His earlier career in entertainment included a variety of other experiences, including as a background actor on the West Wing and operations supervisor at Universal Studios Hollywood.

Jeff’s interest in public policy began while pursuing his bachelor’s degree at Gustavus Adolphus College, where he took on a leading role in the school’s LGBTQ+ Network and was a co-creator of the theater project Voices of Diversity. He later joined the board of the LGBTQ+ focused Outfront PAC and volunteered on the Minnesotans United for All Families campaign for marriage equality.
