I don't know of any swim programs that also offer diving other than swimmer pools/teams. Unless by diving you are referring to working on swim starts.

Swim with Beth does starts 4-4:30pm every Sunday at the JcC on little river turnpike.

Can you suggest any swim organization / team to learn Diving . Kid is familiar with all the strokes(legal) and swim 25 yards. Looking for swim classes to continue swimming along with diving . Any suggestions on teams near South riding/Brambleton /Chantilly

Thanks
