My Story

How do you just make things happen?

People have asked me my whole life how I just make things happen. I never had a good answer until recently.

As a Spanish speaking missionary across three states, I inherited the territory everyone before me had written off. I built it into our most productive account through one relationship that unlocked everything. A corporate career that took me from Vivint Solar, where I identified a $2M opportunity and sold it to senior leadership, to Goldman Sachs, where my hiring manager called my interview one of the best he had ever seen. Most recently, finishing my EMT program in the top 5% of my class and finding myself in emergency rooms and trauma bays executing under pressure alongside physicians.

Different rooms. Same instinct. Read the person. Understand what they need. Earn their trust. Find a way to close the gap. That is what I have been doing my entire life. In medical sales it just finally has a name.
