Just so grateful to our industry partners and for encouraging us to have our company join .

It’s been such a blessing to be surrounded by other companies who all share in the desire to support our local community.

Late last year it was our turn to nominate a nonprofit and after an incredible presentation by April Casillas, her nonprofit was selected.

April is a survivor of human s*x trafficking and warrior for other victims. She fights daily to help victims with many services including recovery and relocation assistance.

I met April while mentoring s*x trafficking victims and have been blown away by her story and all she does to help others daily.

Thank you so much 100 Companies that Care for all you’re doing to help nonprofits in Orange County.
