I totally agree with everything Rich said about working with Cathy Church and her group.
I was very impressed with Cathy, not only with her knowledge and abilities, but also with how generous she is with her knowledge and her eagerness to ensure that all students get the desired results. I don't know where anyone got the impression that she is grouchy, because I never saw any indication of that, and as he mentioned we spent a lot of time with her.
As he mentioned, Rich worked with Cathy during our trip and I worked with Kat, who was also very good. Even though I was not working with Cathy directly, she was always concerned with my results after each dive. It is incredible how much my abilities improved after working with them.
So Pitdvr, as Rich said it is definitely worth your time/money to work with Cathy while you are staying at Sunset House. But I suggest that you plan to spend more than an hour to make the best of your time. You want the setup time, dive, and than post dive discussion, which requires more than one hour.
I would highly recommend Cathy Church to anyone traveling to the Cayman Islands. If you decide to work with one of her other people, you will also be very happy with the results.
I can't wait until we get back down to the Cayman Islands to work with Cathy, Kat, and the rest of the group more. Hopefully we will be able to get back in the next few months.
