Dr.Powar is compentent and I had a decent C section and issueless post partum experience, thanks to him! I have heard from other friends that is very good with complicated cases. He doesn't talk much - if you want someone communicative and hand-holding types, don't consider him. If you don't mind the lack of much Q&A and are happy to be in good hands and trust your doc, go to him!
Initially I felt a bit frustrated too and wished he wouldn't be so brief in his responses and sometimes dismiss my questions, especially since it was my first pregnancy. But hey, he was on top of all important issues and did an excellent job with my C section. I didn't have any issues some of my other friends had during /post their C. I definitely recommend him.
