Alfred Joel Horford Reynoso was born in Puerto Plata, Dominican Republic, to Arelis Reynoso and Tito Horford. His father was drafted in the second round of the 1988 NBA Draft and played three years in the NBA for Milwaukee and Washington. Horford's uncle, Kelly, played college basketball at Florida Atlantic University in the early 1990s, while his brother Jon played for Michigan and Florida. Al Horford has two other brothers -- Josh and Christian -- and two sisters, Anna and Maria. The Horford family moved to Lansing, Michigan, in 2000. There Al attended Grand Ledge High School in Grand Ledge. As a senior, he averaged 21 points, 13 rebounds and five blocks per game and was named Class A Player of the Year. Horford ended his tenure at Grand Ledge with seven school records, including most career points (1,239). Horford has been involved in many charitable causes since reaching the NBA. He was awarded the NBA Cares Community Assist Award for March 2011, in part due to his support relief efforts in Japan and the Pacific region following a devastating earthquake and tsunami. In 2019, he partnered with the Built With Chocolate Milk campaign to put on a basketball clinic for 30 middle school and high school students. He has also been involved with Basketball Without Borders, the Make-A-Wish Foundation, the NBA's fight against AIDS and as an ambassador for elephants and rhinos with WildAid. In addition, Horford spent a summer reconstructing basketball courts in Puerto Plata, his hometown, and put together youth basketball clinics. In 2020, he donated $500,000 to support coronavirus relief in the Dominican Republic as well as in each region of the United States where he's played for a team.
