Hi L.! I'll piggyback on Tracy M. with Dr. Castelli. I've actually never met him, but I know his wife very well and if she's any indication of how compassionate her husband is than you're set!!
I was not recommended to him when I first moved here so I go to the practice of Dr. Maggie Peden and Assoc. out of Lankenau Hospital. She is very kind and has a great bedside manner. There are 2 women (Patricia McConnell) and 2 men. You could schedule your appointments with just the women! But keep in mind that you can't control when you deliver so you might get one of the men, who are both good as well.
Best of luck to you! I would just encourage you to be up front with the OB's and express your fears and if they write you off, write them off!!
