Dr Shefer has delivered both of my sons and is a great Doctor. Both of my pregnancies were high risk and she made sure that all options were discussed and evaluated. I highly recommend her to anyone who is looking for a thoughtful and professional Doctor.
I visited her in the Park Slope office and wait times are usually 15 - 20 mins if you aren't the first appointment. Other than that, I totally trust her with any recommendations she may have.
