The present study examines the relationship between four career success variables--salary, promotions, subjective career success, and job satisfaction--with experience as an informal mentor among employees of a health care organization. Regression results indicate that individuals who serve as a mentor to others report greater salary, greater promotion rates, and stronger subjective career success than do individuals without any experience as a mentor to others. The results provide preliminary evidence supporting the notion that career benefits are associated with serving as a mentor to others. (Contains 2 tables.)
