Outcomes:

My wife experienced heavy bleeding on a friday during the first trimester. We went in immediately to see Dr. Tan. She wa...s not cordial towards us. We waited 20 minutes to see her. She walked into the room, asked us what was going on, put on a pair of gloves and gave us an ultrasound. She told us that unfortunately we were having a miscarriage and that she recomended we schedule a DNC three days later on the coming Monday. We told her that we wanted to wait and see if the fetus would pass on it's own over the weekend (avoiding any non-essential procedures) and that if it did not pass we would call her Monday morning to schedule the DNC for Tuesday. She said in a pretentious manner that it was our choice to wait, but in her professional opinion we should get it done on Monday. She then told us that her job can be very difficult and that we were the second miscarriage she had seen on that day and it was only 10:00 in the morning. She then walked out of the room and my wife and I could not believe that on the worst day of our lives, Dr. Tan was telling us how difficult her job was. She saw us for a total of 5 minutes. On Monday morning my wife called Dr. Tan multiple times without a call back. She continued calling every hour or so throughout the day. Finally we received a call from a nurse at 5pm apologizing for Dr. Tan having not called us back. She said to call again in the morning the next day which was Tuesday. We immediately called my wife's OBGYN at West Hills hospital and scheduled a Tuesday morning appointment for a second opinion. Our doctor at West Hills was shocked that Dr. Tan would try to schedule a DNC so quickly. Our doctor at West Hills told us that there was a chance that maybe our bleeding was a common case of pregnancy bleeding and that we needed to wait 2 to 3 weeks to make sure we were indeed miscarrying. She told us that every now and then she'll get a patient that you would think was having a miscarriage due to the symptoms they are experiencing and it turns out 2 or 3 weeks later you'll find the baby has a heartbeat. Sure enough, two weeks later our HCG testing revealed that her levels had increased, consistent with a healthy pregnancy. We still did not see a heartbeat on the ultrasound so our doctor at West Hills told us to come back once again in another week. We returned the third week to the surprise of a healthy heartbeat in the wound. 
Had Dr. Tan returned our phone call as she promised on that Monday we would have scheduled a DNC for Tuesday and she would have killed our baby. We have a $35 dollar bill from Dr. Tan's office that we will not pay by principle. Dr. Tan's office will not even waive the bill for us. A month later I told the story to a friend who revealed that a family member of hers had the same misdiagnosis by Dr. Tan within weeks of our experience. She almost killed 2 healthy babies in the same month. How many other babies has she killed in her rush to perform immediate DNC's without properly test for increased HCG blood levels? We also talked to Dr. Murphy who is the head of that practice at a hospital function weeks later and he expressed his disbelief of her behavior. Consult Dr. Tan at your own risk. She inflicted severe emotional pain into our lives for the 3 weeks we waited to find out our baby was alive and healthy. more details
