The doctor himself was alright, very old, maybe in his 70's but still alive and alert. His mother, the receptionist aka office manager aka billing clerk aka his boss...is this old lady maybe in her 90's or 100's years old. She was just a pain in the bleep. She asked to fax records to her, 3x and she claimed she didn't receive them. I tried to make appointments a year ago and finally got one. My advice is call your insurance company and complain about this practice, unreasonable appointment scheduling time, delays, and demands. read more

I wouldn't go back, just how everyone explained. The receptionist is dreadful. I had to ask my primary to change where I go for my endocrinologist. read more

Don't go here, the receptionist is incredibly rude hangs up on you does not do her job the way it should be done! She is the Doctors Mother so he will not fire her, I found another Endocrinologist, when I complained to Dr Tran about her he brushed it off, its a shame because I liked him. As my Doctor but dealing with her is stressful, even sitting in the waiting room. She glares at me me like what are you doing here kind of look​ ,I found another Doctor...fire Kim the incompetent receptionist! Very Unprofessional read more

I made just one call as a new patient and I'd rather have my primary care manage my diabetes. The worse customer service I've ever encountered. I thought I was having a bad day but reading these reviews, confirmed it. Can you imagine dealing with them trying to get a refill let alone care? No thank you. My insurance should kick them off the panel. read more

If I could give the experience I had with this office a ZERO I would have. The front office staff, with the doctor's mother answering the phones are exceptionally rude. I was hung up on several times trying to make an appointment. Incredibly unprofessional. I got a referral to someone else. Avoid at all costs. read more

The receptionist, who also happens to be Dr. Mom, is incredibly rude and incompetent. Despite several attempts to schedule an appointment, I failed each time. Eventually, I gave up and sought a different doctor. read more

Zero stars, negatives if possible. The receptionist if you can call her that was the worse!! They attempted to charge me $130 for the visit even after I had my insurance speak to them and inform them that my copayment was only $10. The staff is very unprofessional and the office its self looks run down. Go else where is you want to be taken care of read more

This review is for someone other than Dr. Nicholas T Tran, MD who is friendly, caring, and knowledgeable. I know you're leading a highly competitive Endocrinology, Diabetes & Metabolism office in California, so I'll get right to the point. I have never gone out of my way to write a Yelp review about any service provider because I am extremely busy with my work. But in this case, I must feel that I must. Regarding the front office: I highly recommend the front desk staff to enroll in an interpersonal skills class. The staff were very rude and unprofessional to myself and other patients in the office at the time. I have never seen such awful customer service in a professional office before and, quite frankly, do not understand how these people are deserving of jobs. Please do not let these people continue to represent your business even if they are your family member. If you lose patients or have trouble retaining them, the front office staff are the reason why. I highly recommend that the front desk staff become educated in interpersonal skills and customer service because they need to be retrained or fired. read more

You can't fire the receptionist Kim, BC she is doctor's mother...she is definitely rude. She doesn't care about what insurance you have, just ask you to pay $100.00 before you can see the shitty doctor. read more

Funny how I am actually sitting right on front of the office writing my review. I can attest that every single comments on here is accurate. My mom had to wait for two months for the appointment. She has HMO, so pretty much all of her paperworks, insurance information, and authorization have been forwarded to the office before we showed up. We even brought another copy of our paperworks, lab-works, and authorization with us. The only thing my mom forgot was her insurance card. So the old receptionist lady (I believe her name is Kim...there was another receptionist but she was even more clueless than Kim) told my mom that they can't see her because without a copy of the card they won't be able to get paid by the insurance company. BS...a copy of the insurance card is just a proof along with the ID card. No insurance company asks for a copy of the card when you bill them, either with the CMS1500 form or on their billing website. She wanted to reschedule the appointment. I told her I don't want to reschedule the appointment. I showed her a copy of the card saved in my phone and I can email her the copy I have on my phone...she said the office doesn't have an email address. It's 2021 and the office doesn't have an email address. Plus she doesn't know how much copay to collect ...damn it...it listed on the copy I have on my phone. The most basic standard procedure for all doctor offices is to verify patient's eligibility, copay, and insurance benefits before the patients showed up to their appointment. I didn't want to make a big deal at that moment, so I drove to my dad's company to pick up the insurance card for her to make a copy. Ridiculous!!! Calling our insurance for another endocrinologist!!! Only if I could give a no stars review!!! read more

Nicholas T Tran, MD - Endocrinologists Near Me - Westminster, California

please don't come here... Service is so terrible... the lady( Kim) in reception talk not nice... if you don't want wait time... please find another doctor read more

ZERO STAR FOR THE OLD RUDE RECEPTIONIST I came with my mom to book appointment for her but we forgot to bring the introduction paper. But my sister sent me the picture of that paper to show her! Then I don't know why she got angry and said that the modern technology made us become "STUPID" Omg Is she a receptionist for a doctor office? Then she continued to be rude even I just asked politely that which days the office opens then my mom can come back with the introduction paper because she didn't book any appointment for us! We left the office and I had to go yelp to review this office right away. I read all the reviews and noticed that every one got mad at the service of the old rude receptionist read more

I dont know why they still havent fire the old rude receptionist. She was a pain in the ass. I had to call my family doctor to refer me to a different thyroid doctor bc the Kim was so shit. I hope one day she is updated enough to read all of the complains abt her here. read more

I am appreciate of the hard work and service Mrs. Kim provides on my every visit. Everything you would want from a professional Dr. and office. Exceptional. Very satisfied with the service provided to my mother. Thank you. read more

Rude receptionist needs to be fired. Shes not friendly at all. The place isn't even busy. They wouldn't let me go home and print out the lab work and come back and wait to see him. I waited 2 months to see him. Now I have to make another appointment and wait till probably the end of the month to see him. She don't seem to want to work there. He needs to hire someone else that's friendly and know what to do. All I can say is...the longer I stay there...the more irritated I get of her. Maybe is the way she speaks to me... read more

Beyond rude receptionist. Absolutely the worst person to be in this job position. I haven't even went to my first appointment yet and decided to check my appointment time over the phone. Did not want to help me because she "DOESN'T KNOW", and then proceeded to hang up on me. Don't go here even if your insurance referred you here. Please look for someplace else. read more

Health care truly demands of kind hearted people who are equipped and prepared to deal with the sick. However, if you attend this location be prepared to deal with Kim the receptionist. She is remarkably rude and does not feel the need to filter her unprofessional behavior. Sadly, she diminishes Doctor Nicholas T Tran's professionalism. Nonetheless, don't be fooled Dr. Nicholas T Tran is a great Doctor who is merely in need of a suitable receptionist. read more

I love Dr Nicholas but I have to leave him , because I couldn't handle the old receptionist I don't know why so many bad reviews about her , seem Dr Nicholas didn't care about it :( My mom said bc she still working there you know why?(in law Family) read more

The other reviews are correct. The receptionist is terrible. I don't know how he is able to stay in business with such a terrible receptionist. She doesn't even want to let people make appointments read more

I would give the doctor himself 3-star; he's ok. HOWEVER, his assistant KIM is h.o.r.r.i.b.l.e! No customer service skills what-so-ever. We called to confirm my mom's appointment and she says that she gave us a reminder card so go find it, she can't look it up. WHAT?!?! Basically, she makes things very difficult for patients. It's very sad. She has this attitude like she's the boss and it's her way or else she'll make it impossible for you. Be warned. read more

I has been an outpatient of Dr. Nicholas T. Tran as a specialist for thyroid disease since 2012 so far. Under his medical treatment for my thyroid disease, my health has been improving very well. I would like to recommend this specialist for other thyroid patients. There is just one thing you should bear in mind when you visit the office of Dr. Nicholas T Thanh: Be careful with his receptionist. That is an old female receptionist. Her name is Kim (Vietnamese woman). She is not friendly with patient. She had driven me crazy a few times. read more

I took my daughter to Dr. Tran and he stopped her thyroid meds. In Jan. 2018, we had labs and her thyroid was so high that it threw the rest of her numbers out of control as well. Now she is back on thyroid meds again so everything should go back to normal. I knew he shouldn't have stopped the thyroid again but he said he knew what he was doing and that he was the doctor. read more

I have a referral and try to make an appointment. Just to get the referral to them is a major task. Afterthat, making appoinment is another major task. After I got the appointment, I said fuck it, I rather go somewhere else. The receptionist are rude, jackass, immoral and inconsiderate, don't know what else to call them, lowest live on this earth and waste of space. It's not the Dr. false but he lost a customer. I can't believe Dr. still have them work for him. I would fire them already. It's zero star by the way. read more

I have not ever posted a negative review to let anybody down except this time, because his receptionist did hurt the feeling of my family member. My family member is a patient of Dr Nicholas Tran, and he's a great doctor. We have no problem with him except his receptionist, Mrs K. Patients who are suffer from their illness and that is the reason why they visit medical office. In this case, Mrs K is so rude, she behaves as if she is the king at that office, and everyone including patients must obey her order in order to please her when they come there. She used to verbalize that if there are any conflicts or arguments between her and patients, the doctor will stand on her side, not patients side. This is the worse statement that I have ever heard. I think Mrs K is completely not suitable to work at the medical filed. I think this position should be for person who are nice, careful and passionate. Dr Tran is on his way to build his prestige while his receptionist, Mrs K, is destroying what he has builded. And obviously, destroying is always faster and easier than building. I hope Dr Tran should respect your patient by listening these comment, and there are many negative comments about her. I will ask my family to change to another doctor. The last advice for Mrs K. You need to be re-educated. you should go back school to learn the way human treat with each other, and if you are not respect yourself, you still need to respect patients and Dr Nicholas Tran read more

Dr. Tran is a great doctor. He spends his time with you and is very professional and nice. That is why I gave 3 stars and not zero stars because his main assistant(older Vietnamese lady, believe her name is Kim) is very rude. She got mad at me because I didn't know when my appointment was in December. When I went to the office to pick up the form I needed, she looked in the stack of papers to get it and didn't find it. She then started to look at the charts to see if it was there and someone else was helping her too. After a while of me standing there while they looked, Kim looked through the stack of orders again and she found it. If this office had computers to put all the information of its patients like all the other dr. offices do, their wouldn't be so mistakes made and it would be more useful to the staff and patients. I'm pretty sure this office doesn't have computers because the two old ladies that work there don't know how to use computers! The main rude lady definitely needs to be fired and Dr. Tran needs to get computers and new workers that know how to use computers and are nice. From reading the Yelp reviews, Dr. Tran has lost many patients because of the rude older Vietnamese lady..... read more

I can't believe how rude his assistant is to patient...she ask if i was married n i ask yes. Then she said why didnt u mark "x" here (pointing in the paper). After i put the x in the box, she said "u're grown why do u write so sloppy? " i feel that as long as you can read my writing it shouldn't be a problem. Kim speaks so loud in the office even when patients are in there. She is super rude on the phone to patients who wants to makes appointment. I think that the longer i sit here to wait for the dr. More irritated i get. If this is not the only endocrinologist in OC, i wouldn't even come here. Nevertheless referring them to another patients read more

I totally agree with your comment .. When my mom was in Fountain Valley Hospital ,Dr Nicholas visit my mom because he is a specialist for her illness that's why my mom continue follow up with him .. but .. his assistance KIM .. was.. like you said .. I think Dr Nicholas should hire a new assistance . read more
