John Shaddle - Coach (8th Grade Cascade)

John Shaddle is in his first season coaching in the Mercer Island boys' select basketball program as the 8th grade Cascade Head Coach and the 6th grade ETL Assistant Coach. With 30 years of experience as a coach for both boys and girls recreational and select basketball teams, John has coached St. Anthony's girls; St. Monica's boys and girls; Mercer Island girls select; Eastside Catholic boys select; Quick Handle High School boys and girls; and Emerald City Basketball Academy High School boys, additionally as a Skills Trainer.

John played in high school at Bishop O'Dowd High School in Oakland, CA (1981 California 3-A State Champions) and in college with a 4-year scholarship at Carroll College in Helena, MT, (1985).

John's coaching philosophy with all of his teams emphasizes respect for teammates and coaches, on and off the court. He expects his players to practice hard, try their best, and most of all, work to improve their basketball skills every day. He also impresses on players the need to prioritize family first…then school work, then basketball.

David Loutsis - Head Coach (7th Grade ETL)

David Loutsis is in his first season coaching in the Mercer Island boys' basketball program as the 6th grade ETL Head Coach and the 8th grade Cascade Assistant Coach. He grew up in the Bothell area and is currently a resident of West Seattle. David's coaching experience started 8 years ago as a Catholic Youth Organization (CYO) coach for St. Brendan's. Since then, he has coached with Puget Sound Flight, Mercer Island select girls, Eastside Catholic select boys, Quickhandle AAU, Emerald City Basketball Association (ECBA), and now Mercer Island select boys.

David's philosophy is simple: on the defensive end, pressure the ball and trap the whole time while giving 100% effort. Offensively, push the ball for fast breaks and run a motion-style offense with a handful of set plays. David enjoys teaching the players that preparation and practice is key for team and individual development and success.
