I had both my children at Sherman. I'd have to say they do an adequate job of delivery and the delivery rooms are nice enough, but don't expect any above and beyond from them. I think they are just overworked, maybe a little understaffed.
Some of the people I dealt with were super friendly and I'd recommend in a heartbeat, but there were a lot of instances where I felt like I was just another numbered sheet in the stack of patients for them to deal with. My children were both born perfect and healthy though, despite some complications from gestational diabetes that had them especially worried the second time when I needed insulin to control it. With the second pregnancy everyone I saw was through Sherman in some way or another, including the OB-GYN. However, they didn't page her soon enough and didn't have enough staff to keep track of my progress - the nurse wanted to be SURE I was ACTUALLY in labor before giving me drugs after the doctor told me not to come in until I NEEDED drugs for the pain! - I was there over an hour before I got any relief and then didn't get the epidural because she wasn't around to tell when I wanted to have it! The doctor almost wasn't there in time. She literally threw her arms into the gown upon arrival and then flew forward to catch the baby that the nurse had been trying to hold inside me!!! I'd had a quick labor with my son too, but they didn't seem to take any of my first pregnancy into account when dealing with my second one. They were also really busy, so they put me in a shared room even when I asked for private and then didn't seem to make any effort to move me over until it became a problem. I didn't get any sleep for at least 48 hours because the people in my room were partying about the other lady's new baby. One nurse finally noticed me in tears and cleared out the (at least 10) visiting people in the room until she managed to get me into a private room about an hour later.
Also, after offering to take my daughter over and over again, the nurses didn't want to take her for me when I finally did ask them to let me get a little sleep! They brought her back after a half an hour, saying she was hungry when she was just overtired from not sleeping either! A couple of nurses were superb, however, and stepped in and helped a bunch - one of them is the REASON I'm still breastfeeding my daughter, since I was ready to quit right there in the hospital as I was overtired and having trouble getting her to latch.
Don't get me wrong - they work hard over there and DO do the job needed. I had a head injury several years ago and it was touch-and-go for a while, but I came out okay (10 days in the hospital, 5 of which were in ICU). The beds in the regular rooms - suck. They are as uncomfortable as hell. Bring your own pillows if you have to go there. But the doctors and nurses DO get the job done, so you wouldn't have to worry that they will do anything wrong medically. Just don't expect more than the occasional person to go above and beyond what's deemed "necessary" for them to do. Not enough of them have the time for that I think. Too many patients. When I planned appointments I'd plan a good hour into the schedule just to wait for the paper bracelet to go for a test. Sometimes it would be five minutes. Sometimes it would TAKE the whole hour.
In an emergency, I think I'd rely on them to be competent. However, I'd pick a different hospital for birthing if you have options. I've heard wonderful stories about "extras" that some of the other ones do to help make it a special experience.
