Christopher Schlegel

Head Age Group Coach


It was clear to Christopher Schlegel's parents that at a young age he loved the water.  After successfully escaping the baby pool gate enough times, his parents decided it was time for him to take lessons.  Chris began swimming at the age of four at Hillandale Swim and Tennis.  Chris grew up swimming at RMSC & JFD and playing soccer competitively year round in Montgomery County.  Chris began his coaching career at Potomac Swim and Tennis before coming to All Star Aquatics in the Fall of 2007.  Chris began as the AG1 coach at Stone Ridge and eventually gained more programs at ASA.  Chris’ practices exhibit his coaching belief in consistent fundamentals, high intensity, strong emphasis on stroke technique and feel for the water.

Mark Lewis

AG1 @ SR + AG2 @ SR


Coach Lewis is a DC native with over 30 years experience coaching athletes at all levels of club, interscholastic, and summer league swimming in the Potomac Valley.  “Fun in Pursuit of Excellence” is a simple description of his coaching philosophy.

As children tend to identify with play, they might thereforebe engaged enough in a sport to choose to build a career for themselves.  Through effective teaching and training, the results of their efforts might thereforegive them a resume as young student/athletes that would empower them in their future lives.

Such was the experience for Coach Lewis whose career as a 12 and Under in Swimming aided his admission to the St. Albans School with a scholarshipaward in 8th grade.  Graduating as a Captain of the STA Varsity team as well aided in his admission to Columbia University after high school.  While in college at Columbia, Coach Lewis relied on his valued leadership experiences as a student/athlete in the sport of Swimming to earn the respect of his peers and school administrators who nominated him for and elected him as a Marshal for graduation.

Coaching Experience:
Asst. Dir of Aquatics St. Albans School 1990-2017
Pool Coach SDS @ STA 2000-2015
Head Coach MVP Dolphins PMSL team 2001-2018
