1. Could you share a bit about your journey in the military?       

I was commissioned by ROTC from California Baptist University as a 2LT. Shortly after I was stationed in Missouri for roughly 6 months where I became a Combat Engineer for the Army.

After graduating from the schoolhouse, I became a platoon leader for a route/ area clearance company where I managed ~30 people. After that, I became an executive officer for a maneuver augmentation company where I managed logistics, planning, and overall operational success for the company.

Then as a captain, I became the commander of a combat engineer company (armored sapper). Once my role there was finished, I became a commander for an engineer Firefighting detachment. 

2. How has your role in the military reserves shaped your skills and perspective?

My role as an officer in the army has allowed me to manage large organizations, operations, complex logistics, hundreds of personnel (full-time and part-time personnel), and act as a mentor/ teacher to other officers. I’ve been able to manage organizations with over 170 people with more than $32m worth of equipment.

All that has allowed me to be a better accountant and manager for my civilian job because I have a wider array of work that I do.

Adding systems to your ERP to streamline expense and receivables. They increase efficiency and accuracy, ultimately saving the owners money.

I go to the gym in the morning, work on solving problems for my team and clients, and then make a home-cooked meal.

Be a lifelong learner. Always ask how and why someone is doing something.

Growing up, I wanted to be in the military and work in finance. Thankfully, I am able to do both.

9.  If you won $1 million, what would you do with it?

I would start a nonprofit to benefit veterans, firefighters, and police officers.

10. What is one skill every person should have?

I think everyone should have a basic understanding of finance, specifically understanding a company’s P&L and the time value of money.
