This article reports a series of planned efforts on cultivating a group of teachers of English as a second language (ESL) into a community of practice (CoP) for sustainable professional development over a period of 10 months. This case study shows that planned efforts enabled teachers from different backgrounds to learn and develop as a professional and as a CoP. This community could be developed through different stages. The authors learn that sensitivity, honesty, self-awareness, and individual commitment of the participating teachers helped resolve tensions and dissonances arising out of different teaching approaches.
