I first came to doctor for medical problem. the doctor gave me the exam and told me to go Steinberg for xray and ultrasound. they said that they will send the referral to Steinberg. I made the appointment and went 2 weeks later to Steinberg and when I went that morning, the people at Steinberg said that they never received the referral. the people at Steinberg called the dr. yao office to get referral . when Steinberg finally received the referall, I realized after the xray that the tech xrayed the wrong area. I asked the tech and they said that this was what was requested on the referral. the tech told me that the result would be sent to the doctor within two days. after two days I called dr. yao office and asked for result. the receptionist had an attitude on the phone and replied that I have to make an appointment to get the result. I made the appointment and saw the doctor. I told the doctor what happened at the clinic and she replied that Steinberg was bad and now referred me to pueblo medical for the lower stomach ultrasound. this time I asked the doctor for a paper referral. I did the ultrasound with no problems at pueblo. I called the doctor office to get the result about one week later and the receptionist at the doctor office was growing exceptionally rude. I have come to realize that it was not the fault of Steinberg for xraying me in the wrong area but It was the doctor office for not giving the correct referral. the referral had to come from the doctor to the staff. I have found that the staff has a very poor customer service.
