Coach Jennifer moved to South Lake Tahoe when she was 4 years old. She grew up in Tahoe and began swimming for Tahoe Swim Club when she was 10.

In 1990 she was #1 in the state of Nevada and ranked #6 in the nation at the 2-mile run.

Coach Jennifer married her awesome husband in 2001 who she’s known since she was 4 years old. They moved to Gardnerville in 2001 and have 3 kids who are all Dolfin swimmers. Coach Jennifer has been a coach for DDST since 2017. She loves working with kids and loves being a coach for the Douglas Dolfins!!

Gerald Koch Assistant Coach

I began my coaching career in Colorado at Arapahoe Country Club at the ripe old age of 18. A few years later after some education I joined the Aurora swim team as a summer assistant. Then back to school where I swam and played football.

Soon after I relocated to California. Where I coached a YMCA team. My only swimmer got a DQ in the 400IM, my diver was 6th.

Moving along I finally moved to De Anza Swim Club. I coached on an outstanding staff. After a very successful 1976 Olympics I was selected to Coach the Taiwan National Team. This was an adventure. The Taiwan Swim Committee staged a fantastic wedding for me and my wife Janet 44 years later still going strong. An interesting side note neither of us speak Chinese.

On our return I founded Fairbrae Swim Club. We went from a country club summer team a solid Pacific Swimming team. Several swimmers were High School All Americans and were awarded college swim scholarships. We then merged with DACA. The De Anza/DACA club produced multiple Olympians. An several GOLD medals.

An Interesting note during most of my coaching career I was a full-time employee of several major bay area companies (Lockheed, National Semiconductor, Tandem Computers) We also added two son’s to our family. Yes, they were swimmers.

I was the swim school director for DACA we taught 3500 lessons per week. In addition to my coaching duties at DACA I coached the De Anza College Men’s and Women’s swim and dive teams. Interestingly one of the divers won the 1- and 3-meter diving championships at the California State Community Championships. Not that the swimmers didn’t perform well.

I was the developer of an aquatics and exercise program for seniors at Foothill College. Covid came we left and here we are in Nevada.
