About Our CEO & Founder, Chelsea Wilson
The ultimate California girl, Chelsea takes her โcool as a cucumberโ vibe and brings it to her work, keeping composed amidst any challenge โ no matter what fire she needs to put out.
Chelsea has worked in the experiential industry since 2006, starting out at a global agency in New York City and producing events around the world, from Vancouver and Cancun to London and Paris. From hotel openings and pop-up shops to spring break pool parties and A-list concerts with thousands of attendees โ sheโs done it all, and collected some incredible stories along the way.
She moved back to Southern California in 2014 to open the west coast office which led to eventually going out on her own and launching 3CS in 2020. Since founding the agency, she has continued to offer clients first-class work and a personalized experience, and has made her mark. She was selected as one of the Top Women In Marketing By Chief Marketer and honored by the San Diego Business Journal numerous times, including being listed as a San Diego Woman Of The Year; featured in the SD500 as one of San Diegoโs Most Influential Business Leaders and listed to the 40 Under 40.
When sheโs off-duty, she spends time with her husband and two kids on the beach or being active outside. She has a unique gift of being present in both her home & work life.
