(NNPA) — Despite their value, finding mentors still proves elusive to many who need them. A recent Harvard Business Review exploration of diversity in corporate America found that although big-business companies professed their commitment to seeking out and promoting top minority talent, many of those smart and capable employees of color often left their respective companies “frustrated.” Minority men and women who did excel had a “strong network” of mentors and sponsors that offered more than just instruction, they nurtured their careers. Their business journey was made successful by someone else lighting the way. Karen Thompson understands the consequences of trying to get ahead without a mentor. Before joining NAACP Legal and Educational Defense Fund (LDF) as director of its, scholarship program, she was an associate at a respected law firm. Although she found success as an attorney, her road was tougher, she believes, because she did not have a mentor.
