Lauren Rutland

Age Group Coach


Coaching Experience:

Head Coach - Haines Dolphins Swim Team (AK}

Assistant Coach – Hawaii Preparatory Academy (HI)

Assistant Coach - Academy Swim Club (HI)

Head Coach – Westminster Flippers (CO)

Lauren has coached at many levels, from age group through senior, as well as high school. In coaching these various groups in the different locations Lauren has used this philosophy:

Goal Setting: - Help swimmer’s learn how to set goals and how to achieve them. Each swimmer will be provided with a logbook to help with this.

Self-Motivating & Responsibility: - Coaches and others can only get a swimmer so far, swimmers have to learn to push themselves to reach their goals or even go beyond them.

Work Ethic: - Swimming is a LOT of work …a lot of hard work. Through swimming athletes gain a great work ethic. Teamwork: - Though swimming looks to be an individual sport, it is very much a team sport. No one in their right mind would get up that early to go swim a couple thousand yards on their own. We are a team; we are a family that is how we succeed.

Respect: - Throughout their career swimmers are taught to respect rules, other swimmers, coaches, and any involved participants.

“I am here to coach this team. As such I am here to coach each and every one of the swimmers. I strive to see the potential in each swimmer and motivate them to reach their goals and be successful. I love swimming, I love absolutely everything about water and anything I can do in or around the water. Teaching kids and getting to spend time with kids is one of my other passions. I love being around kids and being able to help them grow as a person while having fun at the same time.”
