Since the inception of the Tangelo Park Program, high school and college graduation rates are higher; students’ grade point averages have increased, as have life time earnings. Crime rates are down and real estate values have steadily increased. The program’s successes, however, is due to the community agencies that work together, developing partnerships outside the community, and working towards the same common goal in an enduring partnership that has lasted for over a decade and a half. Harris Rosen brings credibility, experience, commitment, and financial support to the Tangelo Community, defining the new normal for philanthropy where the donor remains actively involved with the program, understanding that genuine and sustained transformation does not happen quickly.
