I was born on the same day as my older brother and my mother. We all share the same birthday and are always exactly the same age apart!

As Director of Project Management, I am responsible for the installation of solar projects across the US, from pre-construction through final completion. I oversee all aspects of construction including quality control, permitting, build schedules, safety, budgets, and best practices for installation.I immediately discovered my passion for the solar industry when I started my career 11 years ago as an installer at a residential solar firm in New Orleans, LA. From there, I continued to develop my career at American Solar Partners and PowerFlex before joining Onyx in the spring of 2022.
