Live music, time with his wife and two daughters, a great book, and suffering through each Seattle Mariners season are the preferred ways Brad spends his time.
TAMI HOLLAND
Board Member
Tami Holland has served with Doxa in Tijuana since 1993. As a newlywed who knew nothing about construction, she quickly formed friendships with the kids she met at Casa Hogar De Los Niños. While her construction knowledge has expanded greatly since then, it’s those relationships that have kept her coming back to Mexico every year since. She has brought all four of her children to Tijuana for house building, orphanage remodels, Christmas parties and quinceñeras.
Now, as a member of the board of Doxa, she is grateful for the incredible ways she has seen God in Tijuana, and is proud to serve alongside them.
