WS Faculty and Staff
2025 Staff List
Oyindamola Akintola
Hi! I’m Oyindamola Akintola (commonly referred to as Oyin), and I’m excited to be coaching the World Schools division this summer. I’ve competed in World Schools throughout high school and previously served as the President of my Speech & Debate team. My WSD team is a two-time Houston City Champion (2023 and 2025), and we’ve had the honor of breaking to outrounds at NSDA Nationals, placing in the top 16 in 2023 and top 32 in 2024. Debate has taught me so many great things, and I can’t wait to help others grow in all those areas too. I’m passionate about making debate fun and meaningful, so let's do it together!
