Uy, I haven't taken lamaze classes specifically in Marikina, but a few of my mum friends did theirs sa Marikina Medical Center and Marikina Doctors Hospital, both have good prenatal programs and usually may in-house classes din! I'd suggest calling their OB departments directly kasi ang schedules and offerings nila ay nag-change, and they can give you the exact dates and fees na current. Marami rin ngayon nag-offer ng online classes if mas convenient for you, so that's another option to explore! Good luck sa preparation, it's really worth it!
