Griff was instrumental in my development at the University of Portland, helping me stay healthy and earn All-Conference honors all three years. The relationships he builds and what he teaches extend far beyond the court, and I still apply it today as a pro.

What stands out about Coach Waller is the rare combination of deep expertise and genuine attentiveness he brings to every athlete. His toolkit spans strength programming, periodization, mobility, sport-specific conditioning, and injury prevention, yet he never applies a one-size-fits-all approach. What truly sets him apart is how he leads with listening — taking the time to understand the whole athlete, their goals, history, and challenges, to create tailored, purposeful, and effective solutions rooted in helping them succeed.
