Southern California

Welcome to the Southern California Chapter...

Where our members bring the California sunshine and the sweet Hawaiian aloha. 

We’re excited to welcome you to our chapter. We are an enthusiastic group of professionals, visionaries, and change-makers who are shaping the way our regions move.

Our chapter is dedicated to fostering collaboration, leading meaningful conversations, sharing our knowledge, and driving impactful change across Southern California/Hawaii’s transportation landscape all while having fun.

Our members gather and bring people together to keep our communities connected and growing. Join us for our events we host throughout the year. Whether it’s a beach bonfire to kick off TDM Week or an exclusive LAX People Mover Tour, we are always excited to learn from each other. Through events, dialogue, and partnerships, we aim to spark bold thinking and build smarter, more sustainable transportation futures.

So here’s to the journeys ahead. Together, let’s keep moving forward.
