Dr. Collins is my doc and I love her. Dr. Fleidner assisted with my c-section when he was with that group, and I saw him once, too - pleasant enough.
But I do agree with the other poster - getting an appt. with Dr. C can be hard. I have had numerous fertility issues and can say, however, that as long as I've been willing to see her at either location, I have usually always gotten in the same week. Her nurses are really good, too and appointments with them are pretty easy.
Overall, I do recommend her - she is very southern and gentle, but has a wicked sense of humor (Once told me she would fake schedule an appointment for me whe I was pregnant just so I could come sit in her waiting room and read for a few hours).
My c-section was unexpected and was an emergency and it really wasn't until afterward that I understood just how serious it was - she was just so calm and confident about everything that I didn't doubt her. She has that steel magnolia quality to her, is the best way to describe it.
