Natasza Krajcovic

AG2 at SAC + AM Workouts at SAC


Hi I'm Natasza. I've been swimming for about 20 years and I coached USS and high school swimming in Chicago and Boulder, CO. I have had the pleasure of watching my oldest daughter Zosia swim for SRST since she was 7.

During the day I teach math and write math curriculum while chasing my 4 year old around.

I look forward to seeing all my swimmers at the pool.

Hi! My name is Ali Davis and I am excited to have the opportunity to coach the gold and silver groups at SAC! I was a competitive swimmer from age 8 through college. I swam for Issaquah High School (state champs!) and CWU (with Coach Ben!).

I am currently a teacher, a wife, and a mom to 3 active children. My youngest, Quincy, swims for the Stingrays and I am thrilled to be able to share my love for swimming with her!

I look forward to getting to know families and developing strong competitive swimmers!






Darrell D Cray

AG1/AG2 - at Mariner


Completing my AA in business at Bellevue college, while also studying to obtain my project management certification. I am currently a Certified Pool Operator, a Certified Lifeguard, as well as a Certified Playground Safety Inspector. 

In my spare time, I enjoy working on cars, sports, traveling, and being out in nature.

I've had a passion for swimming and being active since an early age. I grew up Swimming in lakes all over the PNW and enjoyed the ocean whenever my family traveled. My competitive swimming background includes four years’ varsity swim team for Mount Vernon High School. My professional coaching background includes 7 months running supplemental endurance & refinement courses for competetive AG1-AG2 swimmers in the king county area;

My coaching philosophy revolves around providing individual feedback, praise, and constructive criticism  in a non discouraging manner. I believe in personal goal setting and creating opportunities for healthy competition and team work in my practices, Throughout my training programs I like to promote the use of fundamental swimming, as well as the refinement of technique in all stages. In addition, increasing physical limits and endurance are a large part of our preparations for swim meets. Most importantly, I try to encourage having fun and being creative while swimming fast towards our goals. 

I'm very exited and proud to be a part of SRST.


Sydnie T Chesley

Silver/Gold - SAC


My name is Sydnie Chesley. I graduated from Lake Stevens in June of 2017. I've lived in Lake Stevens for most of my life. I have competitively swam for 12 years and continue to have a passion for it. After high school I left for the Air Force boot camp, after getting about half way through I got medically discharged. It was a change in plans but I plan to get back on my feet and return to training in the future. However now I am committed to learning how to be the best coach I can be and help further the success of our swimmers on Stingray Swim Team.
