Moving to his family's farm in New Knoxville in 1959, he established the location as the headquarters for The Way's Institute for Biblical Research and Teaching, later The Way Inc. The Way's followers grew significantly in the late 1960s and early 1970s. In January 1968, Wierwille's visited San Francisco to personally witness the Jesus People street ministries, such as those in Haight-Ashbury, where he ministered himself. Some of the groups he met later incorporated as The Way East (based in Rye, New York) and The Way West (based in Mill Valley, California), groups that utilized Wierwille's PFAL class in their ministries. Wierwille had many join him on his trip, marking a period of large growth for his ministry. Wierwille later merged The Way East and The Way West into The Way Inc., now the Way International.
