What makes me, me

The pillars of my life are my family and how I show up for them each and every day. The things that fill the time in between are my love for movies, TV, podcasts, games, reading, and my favorite teams. It all funnels back to staying curious and engaged with life.

Why I left sales

I had the means to pursue a career in design, so I took it. Design gives me so many tools, methods, and room for creativity to solve problems in tangible ways.

Then I joined a boutique design bootcamp, where I worked with 3 different startups at the same time which led to me landing my first paid role.
