Namaste in Royal Oak offers it. I think Beaumont also has a class you can take as part of their prenatal education classes, their web site would have info on that. GL!
I take the class taught by Beaumont at my gym, Beverly Hills Club in Beverly Hills (14 and Southfield). The class is once/week, Saturdays at 12:00 and the first class was last week.

I also took the class at the Beverly Hills Club. The pricing is great and the class was wonderful... I met other Mom's in the class and enjoyed the instructor. My friend is taking aqua mom there as well and loves it.
