# Julie Trell – Cal.com booking page > I'm Julie! Founder & Chief Play Officer of Playful Purpose. My background is a bit of a patchwork: business building, teaching, improv, peer coaching, and culture design, all pointing to the same thing: helping people think and work better by taking themselves a little less seriously. I mentor founders, women navigating career conversations, and corporate teams looking to bring more play into how they communicate and collaborate in order to create better business results. I bring the same energy when we meet: real talk, useful perspective, zero judgment. Whatever stage you're at, book some time and let's figure out how we can support each other. Maybe that's designing a workshop for your team, booking a speaking gig, running training sessions, or bringing in one of my playful programs like Baby Shark Tank, Whose Startup Is It Anyway, Bot Joy or hiring some Kidsultants for some projects.
