I feel like a jerk giving a 1 star review to a Children's Hospital, but I just had terrible experience. My pediatrician referred me to here to get a blood test to see if my child had a genetic disease.
After weeks of calling and getting no answer, finally I got an appointment. That appointment consisted of a powerpoint explaining what genetics are and then showing my baby over the webcam to a doctor. The doctor then suggested we get a blood test (which is all we wanted in the first place). After that, I never heard anything from them except for a bill.

So months later, I still don't know if my child has a disease, but I got a nice powerpoint and a bill for a few hundred dollars.
