Our Coaches
Beatrice Sims-Mackie
Program Director & Girls Head Coach
Beatrice has been coaching at WW since the fall of 2024. Since discovering rowing as a college walk-on at Brown, she has gone “all-in” on the sport! She has coached masters, youth, and collegiate athletes, and worked as a software developer for Concept2. Beatrice’s favorite part of coaching is seeing it “click” for an athlete, whether it’s making a technical change or realizing that they’re stronger than they think.

Steve Mascioli
Masters Coach
Steve’s rowing story started on Cape Cod, where summers spent in dinghies sparked a lifelong curiosity about the sleek shells gliding along the Charles River.
After learning to scull as a young adult, life and career pulled him away from the water—until he rediscovered rowing in 2018 with WWRA’s Adult Program. Since then, Steve has been all in: rowing, coaching novices, guiding adults in Learn to Row and Masters programs, and even serving on our Board of Directors.
