Tenacity is a city-wide Boston youth development organization focused on closing the achievement and opportunity gaps for underserved Boston youth. From elementary school through college and beyond, we offer a unique combination of literacy and life skills instruction, mentoring, family engagement, and tennis/fitness coaching that mitigates barriers to success, unlocks potential, and empowers participants. The youth served by Tenacity's programs develop positive identities as students, mentors, and leaders, which opens educational and career pathways as well as opportunities for personal, civic, and professional growth. The effectiveness of Tenacity's whole-child approach is evidenced by the achievements of Tenacity Pathway students: 95% graduate high school and 70% of our high school graduates are enrolled in or have completed college or approved post-secondary programs.
