Beyond The Field
2018 Summer Youth Olympic Games participant
Competitive archery shaped habits that carry into technical service: discipline, focus, and deliberate improvement.
Athletic background
Precision
Archery taught me to focus on details, alignment, control, and repeatable execution - the same mindset I bring into diagnostics.
Discipline
Consistent progress in sports requires patience, repetition, and accountability. Those habits continue to shape how I approach technical growth.
Focus Under Pressure
Archery requires calm decision-making and mental control. In HVAC, that translates into staying composed during difficult troubleshooting.
Continuous Improvement
My athletic background helped build a mindset of practice, feedback, correction, and constant improvement.
