Maaquatics Swimming

Maaquatics Swimming offers seasonal swim programs, summer camps, and swim lessons that include work on freestyle with side breathing and backstroke. The program includes the Spring Pups Program, the Fall Swim program, and other seasonal swim options.

• Ages: 5–18 years old
• Schedule: The Spring Pups Program runs from April to the end of June with registration opening January 31 at 8am, and the Fall Swim program runs from September through October.

Maaquatics, Inc. is run by Mark and Julie Anderson, and Mark Anderson coaches the Fall Swim program. Mark is entering his 32th year of coaching swimming in Marin and is in his 28th year of coaching the Sleepy Hollow Sealions. Mark and Julie Anderson have been running the Sleepy Hollow Summer Swim Lesson Program for the past 20 years. Julie is an All-American high school and college swimmer who swam at the University of California at Berkeley on a swimming scholarship and has been involved in coaching and teaching swim lessons her entire life. All instructors have either swum or been coached by Mark and Julie, are familiar with their style and technique, and go through a training period to teach the drills and techniques Mark and Julie have used for years.

The Sleepy Hollow Spring Pups Program is for children ages 5–9 years old who work on freestyle with side breathing and backstroke in preparation to join a swim team. The Fall Swim program is for kids who want to improve their strokes, become stronger swimmers, and stay in shape during the fall. Their stated goal is to instill good swimming technique by keeping drills simple and fun so kids build confidence and do not over-think, and they identify individual learning styles and adapt their techniques for each child’s success.
