Natalie Longoria - Head Coach

A former Sea Lion and Redwings swimmer, Natalie’s passion for St. Johns swimming is easy to see.

We know she will do a great job! Natalie and her husband Mike are proud parents to Sea Lion, Preston Longoria.


Peter Sperry - Assistant Coach

Peter has been with the Sea Lions for over five years and continues to be one of our swimmers favorite coaches to learn from.  A former Sea Lion and Redwing swimmer, Peter has recently taken a job as Kindergarten Teacher in Dewitt.  Peter still holds a few Sea Lions records that he hopes are broken in the near future.

Andy’s experience will be invaluable to our club as he assists with the weekly training plans and workouts.

Junior Coaching Program

We are excited to introduce the launch of our Junior Coaching Program.  The purpose of this program will be to find and develop strong coaches for the future of our Swim Club.  Working with our current coaching staff, our new coaches will have a chance to observe our practices as well as develop their own coaching style.

We envision the candidates for this program coming from current Redwing (and other local High School) swimmers as well as from our own Elite swimmers.  In addition to a one season “apprenticeship” type of start, new coaches will also be asked to complete lifeguard training and Level 1 and 2 of the USA Swimming and American Swimming Coaches Association (ASCA) Certification Program.  We believe this will give them the opportunity to succeed as coaches and ensure our swimmers continue to get quality coaching.

  • 1 year minimum apprenticeship 
  • Pay rate increase after 1 year apprenticeship
  • Promoted to Assistant Coach after 1 year apprenticeship
  • Level 1 USA Swimming Certification
