Swimming Lessons

Children learn to swim in a safe yet fun environment with groups separated out by grade.  Each group will have a swim instructor and swim aide assigned to teach the children how to swim. Depending on ability, children will learn different strokes and proper diving techniques.  This is a drop-off program only.  This is for the safety of our students and instructors so that children can focus on learning how to swim.  

In order to sign up for this program proof of residency and the child's birth certificate is required. These documents should be brought to the office located at 1 Main Street where the appropriate forms are available.  This program is open to residents that pay Town of Southeast taxes.  Patterson residents who pay Brewster Central School District taxes are welcome with proof of school tax bill.
