About us

Mark and Julie Anderson have been running the Sleepy Hollow Summer Swim Lesson Program for the past 20 years. 

Mark is entering his 32th year of coaching swimming in Marin. He is currently in his 28th year of coaching the Sleepy Hollow Sealions. 

Julie is an All-American high school and college swimmer. She swam at the University of California at Berkeley on a swimming scholarship. She has been involved in coaching and teaching swim lessons her entire life.

Their goal is to instill good swimming technique by keeping drills simple and fun so kids build confidence and don't over-think. They understand and identify kids individual learning styles and adapt their techniques for each kids success. 

All of their instructors have either swam or have been coached by Mark and Julie and are familiar with their style and technique. All instructors are put through a training period to effectively teach the drills and techniques Mark and Julie have been using for years.
