Lucy Ross

Lucy Ross Web Designer Web Manager Experientia Development Partners

Living in this entrepreneurial golden age, Lucy finds it incredibly fulfilling to empower business owners, consultants, and creatives to ‘level up’ with a striking & effective website. Lucy graduated from NYU with a BFA in Film and TV and a minor in Business, so she comes to web building with an eye for framing while understanding how + why customers buy.

As a media maker + web designer, she works with high-vibe clients to create an experience that resonates and feels human… because we are human for cryin’ out loud!

Way too much of what we see from brands is stuffy and out-dated. But media can be medicine and design can be delightful, so why the heck not use their powers for good?

Lucy’s intention for her work—whether it’s a brand video, landing page, or simply an email to a client—is to uplift and shift.

Her production experience includes Nickelodeon in NYC, the BBC in London, Lead With Love and  JAS Labor Day Experience in Aspen. And she can’t lie: it feels pretty cool that two short films she produced have won awards from both Tribeca Film Festival and the Student Academy Awards.
