Need a good swim instructor (beginner) in The SF East Bay

Anyone know of some really good swim coaches in the Rockridge area? I have a friend who needs help with balance and efficiency and I just don’t have the time to work with her on my own. I’d love to refer her to a really patient person with a lot of skill in working on efficiency.

Thanks,

Dave

I know a great instructor/coach named Nancy. She is one of the coaches for Ironteam (haha). I believe you know her…
