In 2005, she graduated from Leadership Oregon, and in 2007 earned a bachelor's degree from Corban College (now Corban University) in Salem, Oregon.

Political career
By 2008 Sprenger had become chairperson of the Lebanon Community Schools' school board. On February 1, 2008, she was appointed to the Oregon House of Representatives to replace Fred Girod who had been appointed to the Oregon Senate. After winning election to a full two-year term in November 2008, she beat Bruce Cuff in the May 2010 primary and then won re-election to the House in November 2010 by defeating Democrat Richard Harisay in the general election, she was re-elected in 2012, 2014, and 2016. During the 2011 legislative session, Sprenger helped support a bill to once again allow people to use dogs when hunting cougars. The bill, which would have reversed part of Oregon Ballot Measure 18, passed in the House of Representatives but failed in a senate committee, therefore not reaching the floor of the senate.
