I am Lynne Zavrski, Owner of Children of the Sea. I moved to Hawaii in 1975, where I was the first female lifeguard on the beach of Waikiki. I was proud to have broken ground for females to join the ranks. I made several life threatening rescues and received a citation from the major of Fasi.

I participated in triathlons, Century bike rides, and the Waikiki Rough Water Swim. I volunteered at Sea Life Park for eight years, where I helped train dolphins and sea lions. I also conducted the Education Department in lectures for school age children. I taught swimming at city and county pools from 1978 to 1981.

In 1982, I started Keiki Kai (which means Children of the Sea in Hawaiian) where I taught private lessons from my home. It was there that I began to develop the individual-paced teaching philosophy of what is today’s Children of the Sea Water Safe Program.  

I opened Children of the Sea in July 1996 in Portland, Oregon. My staff and I would love to introduce your child to the joys of swimming and the security of water safety.


Owner & Director

I have been making splashes in the pool since the summer of 2005. I am originally from Massachusetts and moved to Portland after graduating from the University of Vermont in 2005.

Working at COTS is perfect for me because I love to swim and teach kids of all ages and abilities. Away from the pool I enjoy camping, hiking, biking and running, along with spending time with my family and friends. Lately I’ve been enjoying trail running up near Mount Hood and around Forest Park.

I love connecting with other individuals in the aquatic industry. On an annual basis, I attend workshops and conferences put on by the United States Swim School Association and other organizations centered around recreational education and child development.

I have two kids in the Children of the Sea water safe program. They have been in lessons since they were infants. This past summer, my wife and I welcomed our third little one who will start swim lessons soon! 




Operations Manager

Hello! My name is Sarah and I am a manager here at Children of the Sea. I originally moved from Lakewood, Washington to attend Portland State University and received my Bachelor’s degree in 2006.

Growing up, I swam on swim team for 10 years and started teaching swim lessons in 2001. In 2009, I had my daughter. Since then, I’ve added two more fish, both boys, who are in the COTS swim program. My daughter has been on swim team for the past 3 years. I love watching her swim and recently became a Stroke & Turn Official for swim meets.

In my spare time, I coach a run club at my daughter’s school and I love taking naps!


Pool Manager

Hey guys! My name is Abbie. I’ve been swimming ever since I can remember. I was on my high school swim team and even life guarded for a while. Needless to say, I love kiddos. 

I also enjoy seeing movies, spending time with my family, and cooking!


Office Manager

Hello! My name is Gina and I’ve been working at COTS for the past 3 years. Prior to this I was a preschool teacher for close to 14 years and have a strong business background. I have a son who graduated college and a daughter who is in high school. I love spending time with my husband and kids when the time allows. We enjoy hiking and camping and basically anything that takes us outdoors. I love working at COTS and really enjoy getting to know you and your kiddos!



Hi everyone! My name is Courtney and I have worked here at the front desk since Spring 2005. I enjoy meeting all the families that come through here. I’m excited I get to try out the pool now in the baby classes with my son. In my spare time I enjoy spending time with my family, going to movies, reading, and going on Disney trips.



Hi diddly ho, I’m Aria. I was born in China but have lived in Oregon since I was a year old. I enjoy reading and going to concerts. I was involved in theatre and choir in high school and love to make people laugh. I was voted most talkative in high school so I got a job that involves talking. Stop by the front desk and say hi, I look forward to meeting you.



Howdy doody, I’m Brittany. I recently graduated from Southridge and started working at the front desk this summer. When I’m not at work, I enjoy being silly, hanging out with my family and my dog, Harley-Goose. One fun fact about me is that last year I learned how to juggle. Come say hi at the front desk, but please don’t ask me to juggle because it distracts the children in the pool!



Curriculum Coordinator

Hi Swimmers! My name is Wendy. Besides being a swimming instructor since 1999, I am a mom and grandma, a retired professional golfer, a musician, a student, a preschool teacher, an astronomer, a radiographer, an athlete, a bowler, a camper, and many more things. I have lived in California, Oregon and Washington.

My favorite thing of all time is the Big Dipper. I started teaching at COTS in 2005, and I love it so much that I might stay here until I retire. The warm water soothes my body, the children’s hugs touch my heart, and the parents and staff are some of my best friends. It just doesn’t get any better than that!


Deck Supervisor

Hi, I’m Johanna! I grew up in Oregon and love anything outdoors! I also like hiking, camping and swimming. I have a cat named Kuvu, but I really love any and all kind of animals! See you in the pool!


Deck Supervisor

Hey guys. My name is Lisa and I am one of the instructors here at COTS. I was born and raised in Germany and moved to the states almost 5 years ago. Back in Germany, I worked as a Ballroom dance and kid’s dance instructor since I was 16 years old. I’ve always loved the water and am excited to be a part of the COTS team. When I’m not in the pool, I like to go out with friends, bake elaborate (ish) cakes, watch Friends on Netflix and explore Oregon. However, my biggest passion is photography. I could spend hours with my camera in hand on a photo safari. I also have two younger siblings who are both taller than me and an 8lbs dog named Bugsy. I’ll see you in the pool!



Hello! My name is Teacher Erica. I have been a swim instructor for over 13 years–almost 6 years at COTS. Before that, I was on swim team and have been swimming all my life. You could say chlorine is my perfume. I teach all levels of swimming from tiny babies to adults. I really enjoy working with children and have a couple of my own. After my daughter graduated from the swim program at COTS, she joined a swim team and is loving it! My toddler son loves being in the pool We like to go boogie boarding at the beach, go to the pool, and rock climbing.

See ya at the pool! Life is cool– swimmers rule.



I have never enjoyed a facility as much as I do working her at Children of the Sea! I taught early and elementary education for over a decade. After the birth of my second child, I moved toward a parent advisor and baby planner position which I still continue today. I had my fourth child in 2015 and am very excited that all of my children get to experience the program here at COTS! I can’t wait to work with your children in the water!



Hi! I’m Rachel. I was born in Burlington, VT, but I consider Oakland, CA my home after my family moved there when I was six. Growing up, I tried almost every sport, which is how I discovered my love for swimming. I swam for my high school swim team and have my swim coach to thank for introducing me to swim instructing. I’ve been teaching swim lessons for seven years now, and there are only a few things that give me the same joy as watching my students grow and progress. I moved to Portland from Santa Barbara, CA to finish my undergrad degree, and was fortunate to find COTS and their amazing family.

When I’m not in the pool, I’m usually hanging out with friends or my dog, Boo. You can also find me outside enjoying nature and trying new or off-the-beaten-path type of activities like fire spinning, rope courses, and mountain boarding. See you in the water!



My name is Vivi and I was born and raised in San Jose, CA. I moved to Oregon in 2012 to pursue a B.S. degree in Natural Resources. 

Swimming is all I’ve ever known my entire life. I started out on swim team and spent four years playing water polo and swimming for my high school. Life guarding and teaching swimming were my first two part-time jobs right out of high school!
