Case Study

Building the event venue business at Boulder Flower Farm involved a five-part process: research and branding, website build, marketing strategy and implementation, and customer experience.

About

I’m a curious and collaborative operator driven to build better systems and improve end user experiences. Here are a few things about me...

  1. Working with customers, and simplifying operations are some of my greatest strengths. They’re skills I’ve applied and honed across each role, from customer service to engineering.
  2. Before working in the digital space, I worked in Quality Management Systems for a healthcare company, streamlining and improving electrical and mechanical engineering processes.
  3. Outside of work, you can find me exploring the Boulder trails, painting with watercolor, and handbuilding ceramics.
