I also have used Kinderarztpraxis Römerhof for over four years now and have been very happy there, even starting out with an infant (who just turned 5!)
For myself, I go to Dr. Angela Caddick-she is English, and works in a practice just a few blocks from Stadelhofen and Bellevue. Her website is
www.drangelacaddick.com . Also been quite happy with her, although luckily I have only had to see her for minor issues and general check-ups.
Good luck-pm me if you need any other help in the area!
