Building Stronger Connections

The Gonzalez Team recently had the privilege of supporting Caritas Family Solutions in their 75th Anniversary celebration by contributing to a playground expansion project. Several team members volunteered their time and skills, joining forces with other community members to bring the playground expansion to life.

The collaborative effort aimed to create a safe and enjoyable space for children to play and grow. This playground will serve as a joyful legacy for the community, and we are honored to have played a small part in this meaningful project.
