Lab employees in Fontana partner with Mission Viejo’s office staff to support various initiatives that exclusively benefit the children of Auxiliary of Crittendon Services, who’ve been abused, abandoned, trafficked, and/or are impoverished. Employees from both locations donate gifts, money, shoes, socks and school supplies to help these underprivileged children.
