I just had my twins with Dr. Michael Hall. He only delivers at Swedish and is the only doc I know of that will let you have a breech birth (did that with him 4 years ago) and twins naturally. Feel free to contact me if you want more information. He talks pessimistically but he will let you and your body do your thing until he thinks that its dangerous for you both. He is also the referral doctor for Mountain Midwifery.
