Athletic Background
My background in competitive archery helped shape my discipline, focus, and attention to detail - qualities I continue to apply in technical field work.
2018 Summer Youth Olympic Games Participant
Archery taught me to focus on details, alignment, control, and repeatable execution - the same mindset I bring into diagnostics.
Consistent progress in sports requires patience, repetition, and accountability. Those habits continue to shape how I approach technical growth.
Archery requires calm decision-making and mental control. In HVAC, that translates into staying composed during difficult troubleshooting.
My athletic background helped build a mindset of practice, feedback, correction, and constant improvement.
