glad you found some of those posts! I too found them helpful in making my decision to do a oconsult with Dr. Co. I really liked her, she was very easy to talk to, and listened a lot to what you had to say (I know what you mean about that first consult with Dr. Ch, I found that in his "call-backs" he is not like that though and it's more of a two-way conversation, but the call-backs are not the same as an actual consult you know?). the other thing about Dr Co is that she does the ERs, while Dr. Ch doesn't, so I found it more helpful to talk to her about my situation because Dr. ch and Dr. Co don't agree on my issue because Dr. ch didn't see what happened to me twice (emtpy follicle). I don't mean that in a bad way towards Dr. ch, I just personally found it more helpful to talk to the actual Dr. who did my ER, since they see first hand what happens. I believe they are all schooled by Dr. ch, so you will get very similar overall recommendations, in my opinion.
good luck! I hope to hear how it goes
