"They bring a great deal of institutional memory to how things happen," Hallock said.
But the Anderson family is only one of several with multiple members participating in the program. There are 68 swimmers from ages 5-18 this season - the team's size has held steady near that number in recent years - and there are at least seven sets of siblings on the roster.
"We have quite a few families," Hallock said.
The team convenes every summer for a season that runs slightly less than two months, with practices five days a week and meets on Wednesday evenings against teams from recreation centers, YMCAs and country clubs in other towns.
Parents help with the timing and scoring at home meets and contribute food for pot-luck dinners that follow them.
"It's just a nice, fun, relaxing summer thing to do," Hallock said. "There are other swim teams in town that are a little more hardcore - and my son swims for one of them - but this is really about getting the little kids confidence and making it to the other end of the pool with the basic strokes."
Good experience for Anderson
That's where Anderson comes in. She said she started swimming with the Sharks when she was about 11 years old. Now 21 and a student at Western Kentucky University, she is in her third year as their coach.
"I wouldn't come back from Bowling Green if I didn't have a blast," she said.
Anderson is majoring in child studies at Western, and she said working with these children has been good experience, as has working with their parents.
"I've been really close with a lot of the parents, and I still keep in contact with a few of them over the winter," she said.
Still, she can't do it indefinitely. Anderson is nearing the end of her college years, and she decided several months ago that this would be her last season.
That's when younger brother John and his friend, Eric Smiley, both of whom just graduated from high school, got the idea to succeed her.
The two boys are swimming on the team for one last summer - swimmers are ineligible after they turn 19 - but they're also coaching.
"I wanted to do it one last year, and they're assistants under me to make sure they get the job next year," Anderson said.
The two have already taken to the job, and the kids have taken to them. After the Sharks won their most recent meet, they were tossed into the pool along with Ashley Anderson - that's a tradition whenever the team wins - and later they spent a few minutes teaching the younger kids some dance moves.
One of Anderson's sisters, 16-year-old Emily, is also working with the kids this year.
Their mother, Rhonda, helps to compile the results. The father, David, teams with Eric Smiley's father, Paul, to start the races and officiate the meets as they have done since their children were much smaller.
"We've been doing this for 10 years, maybe," Paul Smiley said.
And Ashley Anderson said she knows how fortunate she is to have their help.
"I couldn't do it without them," she said.
She may be the coach, but her father rejected the notion that she's the one in charge.
"The coach answers to us, because the dads pay the bills," David Anderson joked.
