In 2014-15 Sittser teamed up with Terry McGonigal, former Dean of Spiritual Life, to procure two grants, one from the Lilly Foundation and one a Murdock Grant, worth a total of 1.4 million dollars, which led to the establishment of the Whitworth Office of Church Engagement. Beginning in the summer of 2015 Sittser will work half time as Senior Fellow in that office, in addition to teaching in the theology department.
Sittser won the Hope College Distinguished Alumni Award in 2009. He has also been voted Most Influential Professor ten times by the Whitworth senior class, most recently by the Whitworth Class of 2015. During graduate school he also won the Jacob K. Javits National Graduate Fellowship award.
