"Growing up in South Texas, there weren't many options for people to go to for assistance. Learning about Waterloo's mission and what they have to offer gave me a sense of hope that one day we could provide access to affordable mental healthcare to anyone in our community. I'm honored to be part of an organization which strives to achieve that goal."
