My experience with Mt. Sinai was the BEST!! When I got pregnant with my second son (now 18 mos.) I got references from several obgyn;s, after trying several I ended up with Castillo, Blachar and Brasac. ALL 3 in their own way are very good drs. Some women whom I spoke with at the waiting room didnt like blachar because they said he wasn't "nurturing" enough. To me, I could not have asked for a better dr. than Blachar. He was very sweet, concerned and I felt confident that everything would be alright througout labor and delivery. All of them are expereinced. Castillo is also very sweet and is the oldest, so I assume that he has even years in the field.
All in all, I would recommend them. I liked them so much that I still see them for my annual check ups.
Good luck!
