Summary
BACKGROUND
I recently graduated from Oak Ridge High School and am a disciplined, hardworking individual with a strong drive for personal and professional growth. I maintain a structured lifestyle focused on consistency, early mornings, and continuous improvement in athletics, academics, and leadership. Throughout high school, I balanced rigorous coursework with participation in basketball and golf while maintaining strong academic performance and earning recognition from the College Board. I actively pursued leadership and service opportunities through organizations such as Boys Team Charity and the Regional Occupational Program, including clinical volunteer experience at Marshall Medical Center and medical shadowing with Dr. J. Robertson. In addition, I have served in youth leadership roles within my church and independently gained work experience through community-based jobs such as yard work and household projects, demonstrating reliability, adaptability, and a strong work ethic.
