Meet Our Staff
Undergrad Ministry
Steven Ambo
Area director & campus staff (UW Seattle: InterVarsity Undergrad, Everett Community College, Pacific Lutheran University)
Steven has been on staff for 14 years, serving for ten years in Oregon before moving back to the Puget Sound, where he now lives with his spouse and children. As area director, he oversees ministry in Tacoma, Seattle, and Everett, and he counts it a privilege to be involved in something as personal as students’ faith lives. This year, he is also directly on campus at IVU at UW Seattle, Everett Community College, and Pacific Lutheran University, and is looking forward to how God will work in those campus communities.
