Between Thanksgiving and the holiday season, this time of year is really centered around giving back. As community support is at the forefront of Calix’s values, our team organized a number of volunteer and charitable events for employees to give back this holiday season. We are honored to have taken part in these incredible activities, some of which included, building teddy bears for children in underprivileged communities, recording holiday audiobook for youth with disabilities and even sharing messages of love, hope and seasons greetings through American Sign Language (ASL) for those with hearing loss. At Calix, we believe investing in our communities is an honor and privilege. We look forward to more opportunities to give back to the communities where we live and work.
