Our Talented Team

Luis Guitart is the Regional Sales Manager at Delta Air Lines, based in Austin, where he leads sales efforts working closely with key corporate, civic, and community partners.  Prior to his time in the airline industry, Luis built professional experience in marketing, strategy, and communications across a number of diverse organizations in big-box retail, local news and state government. He is a graduate of the University of Minnesota with degrees in Marketing Management and Political Science. Away from the office Luis spends his time traveling, wine tasting and attending sporting events.

Marissa Grass (she/her) is a self-described local government nerd. When she is not at community events with her two kids, she likes reading, camping, and hiking with her friends and family. Her career in local government spans areas such as city planning, utilities, garbage and recycling, emergency management and parks and recreation. Marissa ran for class president in 8th grade because of her belief that individual action, collectively, is what will change the world. Her book, A Kids Book about Civic Engagement, is a blueprint for how to do just that, and (spoiler alert!) you don't have to be a grownup to do it. Marissa is excited to work with Politisit to make civic engagement a family activity.
