I would (and do) highly recommend Minds Matter. I have been a mentor for 3 years - 2 in Boston and 1 in San Francisco - and I can't imagine a better way to spend my early Saturday afternoons. The kids that make up the program are incredibly motivated and accomplished, each has such a fantastic story to tell and just needs some help learning how to tell it. As a mentor, you have a very postiive, tangible and long lasting impact on their lives; you are often the first person to truly push them to broaden their dreams, and will be amazed how well they can rise to the challenge. In addition, the mentors and exec team members are a great and fun group, and the Minds Matter community is a fantastic social circle outside of our weekly sessions. Highly recommend getting involved.
