Mentoring (healthcare) research from low-to-middle-income countries is critical for developing evidence-based healthcare solutions. This paper presents findings from a study of the mentoring and supervisory relationships embedded in a South African fellowship program for early career healthcare researchers. The findings demonstrate how, rather than relying only on formally assigned mentors and supervisors, the fellows chose to establish a mentoring community. This mentoring community included a network of mentoring relationships which involved sharing career advice, establishing professional networks and cooperation opportunities, and creating a reciprocal psychosocial support community. We conceptualize these findings from a developmental network and mentoring community perspective.
