PRIMARY CHILDREN'S MEDICAL CENTEReverything was good. the only thing is that I didn't get a clear message of what _____ needed the first time. I was truly hoping to do the circumcision earlier than 6 months but they said he's too little to tell if it needs to be an operation or not... so we're waiting the 6 months anyway. just wish I was asked what I was expecting before they spilled out the outcome of what is going to happen. the explanation was great, just felt like my expectations were crashed.

PRIMARY CHILDREN'S MEDICAL CENTERDr Wallis was informative, compassionate, & sympathetic as always. The doctor in training who came in before Dr Wallis however should have viewed my child's chart before coming into the exam room & telling us my child's kidney pain wasn't from the kidney stones & that there was obviously something wrong with her kidney. She's had hydronephrosis for a couple of years now. Of course her kidneys aren't the same size. What the intern ended up doing was freaking me out for no reason which caused me to cry which then made my daughter worried and it never should've happened.
