Intending to foster a partnership between his university and a local school and to create a new identity as a teacher educator in the community, a newly hired assistant professor of English education offered support to a secondary English department and ended up working extensively with the teachers (planning, observing, giving feedback, reflecting, and modeling lessons by teaching classes). This self-study examines the experience of the teacher educator as he navigated this 2-year commitment. A systematic analysis of all data collected (detailed journal, observation notes, debriefing notes, correspondence, and transcribed interviews) reveals how the conditions that allow tensions to become productive -- a need for interaction, a willingness to engage in commonalties and differences, a sense of value for various skill-sets, and a suspension of judgment for the good of the community -- within an emerging community of practice offered opportunities of professional growth for teachers and a teacher educator. This research provides insight into how university professors can better recognize and understand the conditions that allow perceived tensions to function as catalysts for professional development, offering an example of how to improve collaborative relationships between teacher education programs in higher education and K-12 school districts.
