My first recommendation would be to *run* to the phone and consider hiring Eileen Ryan as your doula - she has worked with many different midwives and OB groups in many different hospitals in Cincinnati, so you can tell her really specifically what you're looking for and you'd likely be able to make a really informed decision after talking to Eileen. Plus, she's got such a fabulous demeanor - absolutely someone you'd want supporting you through pregnancy and birth!
As far as OBs/midwives, I've been a patient of 2 of the groups mentioned by other mothers already, but I believe both of these groups deliver at Christ - don't know about Bethesda North:
* Seven Hills Women's Health
Depends on which group you see as there are several different groups. While I *highly* recommend Dr. Teresa Schutte (she attended my 1st birth, unmedicated, no IV, non-interventive for a hospital birth), I did not care for Stevens, Singh, Sutler, etc. (the others in her group). Unfortunately you can't choose who will be on call when you go into labor unless you plan on inducing (which I don't recommend unless there's a true, evidence-based emergency - inducing before 42 weeks increases your rate of c/section and all the other interventions).
* Dr. Vardaka, MD, & Stacy Hudepohl, CNM
Advantage of this office is that Stacy is a *fantastic* midwife, and you can be pretty certain that she'll be the one you see (unless you have any complications, at which point you might have to be under Vardaka's care). Dr. Vardaka, well, I can't speak to her abilities as an OB because we thankfully didn't need her, but her bedside manner is atrocious - controlling, pompous, insensitive, and very volatile, like Jekkyl and Hyde. Stacy is just the opposite - calm, rational, warm, and all-around *lovely* to be under her care. The major benefit w/ this group is that you know exactly who you'll be seeing: it's either Vardaka or Stacy, not some random doc/mw out of a group of 8 other docs. You can request to see Stacy for your pregnancy/birth and she's there unless on vacation (which you can ask her about during your first visits!).
