I used Generations for about 3 years of gyn care and the delivery of DS. The doctor who I saw has since left the practice and only does gyn now, though.
Overall, I liked the practice. My doc was receptive of what ever I did or did not want to do. She also made sure to explain anything/everything to me. I have friends who have used Dr. O'Kelley (part of the group that practices at Parkwest), Dr. Cottam (have said that they would follow her wherever she goes), and I think Dr. McCullum. One of my friends had a successful med free birth at Ft. Sanders Regional with Dr. McCullum.
For this baby, I couldn't talk DH into using Lisa Ross and my work location changed making Ft. Sanders harder to get to. My previous doc recommended a practice at Parkwest and I've been happy with them. It is Contemporary Women's Health and my doctor is Ceeccy Yang. She has been so laid back with all my care. I decided not to do a lot of the testing, ultrasounds, etc and have received no flak from her. She has 4 kids and her last one was born in May. She had a natural birth herself for that one and she is completely supportive and understanding of what I want to happen.
Hope that helps. I'll be having this baby at Parkwest sometime in the next 3-4 weeks and can let you know how that goes, too.
