Arizona Diamondbacks: As part of the D-backs Give Back program, three Tucson organizations were awarded grants of $5,000 each. D-backs employees raised a total of $50,000 and selected 10 organizations across Arizona to receive the funds. The winning organizations are: Assistance League of Tucson, Big Brothers Big Sisters of Tucson and La Paloma Family Services. Assistance League of Tucson will use the funds for its Operation School Bell program, which provides low-income children with school clothes, shoes and other personal items.

Big Brothers Big Sisters of Tucson will use the grant for community-based mentoring programs.

At La Paloma Family Services, the money will be used to purchase supplies and services for Amparo de los Angeles, which provides shelter and support for pregnant or parenting homeless girls ages 12 to 21.

  • BRAKEmax: Staff from the Tucson company helped deliver hundreds of pounds of clothing to the Veterans Administration for homeless and at-risk veterans. The clothes were donated as part of a month-long Veterans Appreciation Event during which BRAKEmax associates performed more than 400 free oil changes for active duty and retired veterans.
