K.,
I don't know of this woman you're looking for but I can advocate for YMCA lessons. The Dale Turner Family YMCA is in Shoreline and hasn't been open a year yet (we opened last Oct). Through the Y swim classes are offered for kids as young as 6 months old. If, for whatever reason, your child would not to well in a group lesson setting there is also the option of private lessons in our pool, and also parent/child classes if your daughter is 3-5 years old.
I teach many of the parent/child classes, and all the levels, as well as some other classes where mom and dad sit on the side and cheer.
"Building strong kids, strong families, strong communities"
Hope this helps,
Melissa

Oh, and if you're interested, registration for the September set of classes will be starting in the next few weeks.
