Leo Grillo, his former wife and veterinary assistant Stacy Grillo, and veterinarian Dr. Gaylord Brown work out of an exam room at the fully-equipped veterinary hospital at Leo Grillo's DELTA (Dedication & Everlasting Love to Animals) Rescue complex in Acton, Calif. Nearly 35 years ago, Grillo thought he could get people to stop dumping dogs and cats in the forests and deserts of Southern California. After more than three decades, there is no end to the number of animals he finds discarded on the side of the road. Delta Rescue is now the largest no-kill, care-for-life sanctuary in the nation for abandoned pets, home to some 1,500 dogs, cats and horses with 50 employees, a state-of-the-art hospital with full-time veterinarian, and his own fire department. Here is his amazing story.
