Yesterday we came together at #TheBlockatBoyntonYards for our annual Friends & Family Day. Good food, great conversations, and special moments reminded us that community is at the heart of all we do. Grateful for the people—inside and outside Tessera—who give our work purpose.

June has been a month of celebration, reflection & connection. For the 3rd year, we marched in the Boston Pride Parade—led by TesserOUT & supported by allies—wearing team-made tie-dye that embodied Pride & community. Thanks #TeamTessera for living our values every day.🏳️‍🌈
