Dr. Dianna Yan, MD

If there is less than 1 star, I would give that to Dr Yan and her office. She told us that she has ordered regular work ups for habitual miscarriage and that all those should be covered by our insurance. To our shock, we got this bill from the lab and apparently, all that she has ordered were considered experimental. We tried to call the billing staff in her office to explain but after having waited for a long time, we got a rude staff named Wendy tell us «Don’t waste our time. Don’t call us again. I don’t have time to talk to you about insurance codes». She said all that without ever hearing our explanation. Then she hanged up on us. We called again because we thought that hanging up on clients must have been a mistake. But she did it again to our shock. Now we are stuck with big medical bills because this doctor doesn’t know what is covered by the insurance or not. What’s worse is the billing staff who is just the rudest person. We will never go back to this doctor.

I came to this office for a usual check with my husband. Dr. Yan without taking any analyses found bunch of infections which she said I need to treat immediately and come every week for a check. She prescribed me bunch of cremes and pills and antibiotics for two weeks. After that she took some samples.
I got medication the same night after visiting her and started my treatment immediately.
After one week I called the office and asked to tell me about my analyses. I was constantly on hold and got disconnected or hanged up on of being on hold for 30 mins. I called 6 times that day and my husband called twice. Finally I was LUCKY enough to talk to somebody and it was the receptionist in the office. Her receptionist told me that all my analyses are fine and I am absolutely healthy! I was surprised because during my doctor’s check Dr. Yan insisted that I have bunch of chronic diseases that she could see it with her naked eye.
I didn’t like the answers that I was given and demanded to talk to Dr. Yan and explained that it’s an emergency.
She called me after several hours. I asked her if I got this serious treatment for nothing, because my analyses were fine. After that SHE SAID THAT MY ANALYSES ARE NOT FINE AND SOME CULTURE WAS FOUND AND I NEED TO COME TO HER OFFICE FOR A CHECK AGAIN.
I was shocked with their not professional work. Receptionist tells me one thing, DR says something completely different.
She never told me what culture I had because it was confidential. Really? Confidential from myself?
I decided to go to the office in person and get all the answers on my questions.
I left my work early and went to their office to pick up analyses. Dr. wasn’t there. Though on the phone they promised that she will talk to me about my analyses.
When I came in, there was only the receptionist who gave me that paper and said: «Here we go». I asked to explain if I am my analyses are ok?
The receptionist was just idiotically smiling…
Then some random Chinese man came in (He didn’t look like an employee of the office and probably was Dr. Yan’s relative, husband maybe) he told me that he never saw me at the office and that I need to leave now.
I was like «EXCUSE ME??» I am a patient here, I pay money and you never spent a minute to explain me what is going on. I left in tears from there, I was deeply offended, mistreated. I got no apologies, the treatment which I didn’t need and huge bills!
Please do not go there!

After I write this review, I finally got my refund $ 1.15 from Dr. Yan. Actually I visited her two years ago. In other words, my upfront payment get refund in two years. Later I got a rude letter which asked me to remove my review otherwise they will pursue any legal action.
I don’t feel they feel sorry for my unpleasant experience at all. In the letter, she explain what I misunderstood such as the deduction and explain «the refuse to take me». Hence, I would like to make further explain about my review. All of my narrative are basing what I experience. Key point is that I remembered I was not welcomed and friendly treated. I have experienced some doctors refused to take me because of my insurance, but they contact my insurance company and explain why they cannot take me. I feel totally ok with that because I feel I am treated respectfully. But I don’t feel the same from Dr Yan.
About deductible, I think I used the zero deductible insurance so that I should pay after the insurance company bill me which is what I get from my school orientation. But I am also feel ok about the upfront charge so that I paid for it. However, I am not happy about after I got the bill from the insurance company and find I paid more, I called Dr Yan and she told me the nurse would deal with the money. Indeed, it should take two years which I can never expect. Although, $ 1.15 is not a big deal but It reached to me very after my review. I don’t want to make any comments about it in case they purse any legal action, but let the readers think about it by themselves.
I cannot make a cent from posting on Unilocal,I just would like to share my experience and what I felt during my visit with others. Two years passed and I still remembered many rude words from her (we speak the same language, there should not be any misunderstanding), so you can tell how angry I was at that time. I was astonished by her manner and attitude as a well educated doctor. If she feel my review brings any damage to her business, i think she should think about it by herself otherwise to blame on one piece of review. I cannot tell any apology from her letter but threat.
I totally understand it is not easy to be a doctor, but I also hope she can learn to respect patients and their rights to share their feelings with others.

I couldn’t help but agree more with the previous review about Dr. Yan. Her brusque mannerism, quick judgment, and unorganized paperwork (they couldn’t even bill me correctly because my insurance number was documented wrong) makes me not want to go back to her. She is the reason I came to Unilocal,to seek someone more medically professional.

I scheduled an early Monday appointment with this woman and since I was a new patient, I arrived 15 minutes early to fill out any necessary paperwork. The building was dark, but the door was open and I sat in this office for 45 mins PAST my original scheduled appointment! I had Law and Order flashbacks and was afraid she was tied up in the back at gunpoint while whomever had broken in was freebasing her stash of Percocet. After calling a few «Hellos?» I realized I was indeed alone. But, if I were a terrible person, there was nothing stopping me from access to her medical records or the stash of meds that an office might be equipped with.
When she finally arrived with her assistant, she was unapologetic and stated her tardiness was due to traffic. It’s not like she’s a new resident of this area — she’s fully aware of commute times. And there were no events or accidents that date that would warrant her tardiness. I checked. The assistant gave me a clipboard to fill out all necessary information including health insurance info, etc. I finished this quickly but had to wait while the good doctor completed arranging the flowers she had brought into with her into a large vase. Perhaps the stop at the floral shop set her back those additional 45 mins???
I have specific medical needs, which I will not get into, but I was not assured with her competency in that I seemed to be educating this woman on my medical condition. I had told her the issues I was having and what my needs were, which medications I can and cannot take (per my General Practitioner), but didn’t really feel like she was listening to my needs. Fair enough. She’s a doctor and has that pretty degree on her wall to prove it. But, there are some things that are in black and white that were ordered by my General Practitioner and if I should sway from those instructions, consequences could be dire. I tend to listen to that guy, but she and her medical degree didn’t feel the need. I’ve listened to this guy for awhile, I’m doing ok — it’s working for me. I just needed her to look at my hoo-​ha.
She sent me for tests (ultrasound, etc) and never got back to me on the results. I actually got the information from the center that performed these tests and she never followed up on a plan of action for the issues in which I first came to her for. Terrible bedside manner. Terrible organizational skills. Terrible listener. And frankly, I found her to be a little judgmental.
Even if she’s the only available OB/​GYN — FIND SOMEONE ELSE!!!
