Mentorship isn’t flawless — and that’s where its power lies. Erik Hernandez, Associate Director for Sports Performance – Olympic Sports at the University of North Carolina (UNC) at Chapel Hill, has built his career on turning imperfect scenarios into lasting lessons for athletes and young coaches alike. For over 14 years at UNC, he has guided lacrosse, volleyball, and golf, adapting his voice to each culture while holding firm to shared standards of accountability and growth. Hernandez streamlines training into a three-phase model — explosive, strength, and remedial — yet emphasizes that delivery and communication matter more than complexity. He reminds athletes, “modifications are part of progress,” linking health, recovery, and seasonal demands to long-term development. For interns and early-career coaches, his advice is clear: earn mentors by serving others, and learn from every scenario, even the imperfect ones. Hear how mentorship, adaptability, and athlete health point the way forward for stronger teams and longer careers.
