Maaquatics, Inc. is run by Mark and Julie Anderson. Mark is entering his 32th year of coaching swimming in Marin and is in his 28th year of coaching the Sleepy Hollow Sealions. Mark Anderson coaches the Fall Swim program September through October. 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 of their instructors have either swam or have been coached by Mark and Julie and are familiar with their style and technique, and all instructors go through a training period to effectively teach the drills and techniques Mark and Julie have been using for years.

They offer seasonal swim programs and summer camps for children 5–18 years old at every skill level. The Fall Swim program is for kids who want to improve their strokes, become stronger swimmers, and stay in shape during the fall. The Sleepy Hollow Spring Pups Program is for children ages 5–9 years old who will be working on freestyle with side breathing and backstroke in hopes to join the swim team some day. Their goal is to instill good swimming technique by keeping drills simple and fun so kids build confidence and don't over-think, and they work to understand and identify kids’ individual learning styles and adapt their techniques for each child’s success.
