My kids ages 5 and 7 have both made amazing progress with Meemo. I think they have been swimming with him now for just 16 weeks and have already completed 2 badges in that time. My youngest did not swim when we first started and my eldest was not confident. We are impressed by how very patient he is with our children especially as at times my youngest can be very challenging. The big plus for me is that Meemo is in the water the whole time whilst teaching. He is firm with them but from what we’ve seen so far an excellent instructor. Would highly recommend him
