Dr. William Dodds is pretty good! He's at Michigan Reproductive:
http://www.michiganivf.com/ He didn't know as much about PCOS as my regular endo, and he did want me off the Gluc at 12 weeks. When I told him my regular endo had suggested continuing it throughout the pregnancy, he said that was fine. He seemed very skilled to me, as well as being caring and compassionate. He appreciates intelligent questions.
His partner, Dr. Young, is equally skilled but I found his bedside manner to be seriously lacking. I saw him for my first consult and he seemed very irritated by all my questions, plus I had a few other not-so-great experiences with him. I avoided him whenever possible, but I did have to see him a few times, and things always went fine (except for not liking him).
Good luck!
