We’re excited to welcome a new face to the Not Just Numbers family — meet Seth Kasten, our newest part-time team member bringing a unique blend of discipline, strategy, and attention to detail to the world of finance.
Seth is currently active duty in the U.S. Navy, serving as an Operations Specialist with a specialty in ASTAC (Anti-Surface/Subsurface Tactical Air Controller). His background in high-pressure decision-making and strategic coordination makes him a natural fit for the fast-paced world of bookkeeping and business management.
Now pursuing his Bachelor of Science in Accounting from UMGC, Seth is transitioning his skills from the deck to the desk — helping clients stay organized, informed, and empowered in their financial journeys.
When he’s not diving into spreadsheets, you’ll likely find him under the hood of a car, out hiking, or spending time with his wife Sofia and their two dogs, Ichigo and Ollie. After living in Japan for three years, he’s developed a deep appreciation for diverse cultures and continues to explore the world any chance he gets.
We’re thrilled to have Seth on board and can’t wait for our clients to get to know him, too.
Welcome to the team, Seth!
