Swim Lessons

I am currently looking for some quality swim lessons for Madelyn for this summer. I want her to be able to go underwater, float on her back, jump in the pool, be able to get out of the pool and know some pool safety. My parents have a pool and with baby #2 coming late summer, I know that she will be over there a lot! Does anyone have any suggestions for some 'serious' swim lessons for a 2 year old (in late June) in the Dallas/Ft. Worth area? All you moms out there...let me know!!
