Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Narcissistic Dr.
I came in to this appointment expecting to hear a lab result and any new diagnosis, but I was disappointed to find that I had a doctor that not only told me the same news I heard last visit, but was also getting defensive with some of the questions and concerns I had. This visit was for almost nothing and the doctor was very unprofessional and unhelpful, which is disappointing for my situation as this is effecting my health.

Can't get through to the office
Called and was on hold for 11 minutes three times and the call went to voice mail so I left messages. I did this 3 times so I drove to the office in Tustin and no one was there. I walked through the office looking for someone and again no one was there. Got home and called again and finally got a hold of Stella. If it was not for Stella I would have just cancelled everything.

Impossible to reach
Very knowledgeable Doctor but he is a bit disorganized and it is impossible to reach his office outside of an appointment. He recommends medications as urgent, but then never sends them in or doesn’t follow up on insurance pre-authorization requests. Same with urgent imaging requests. No one answers the phone at the office and messages go unanswered. The staff will recommend texting their main phone number, but no one responds. I have been waiting for pre-authorization info from the doctor for a medicine he deemed critical, for over a month. No response from anyone.

Dr. Hosseini always takes time to listen to my concerns regarding my thyroid issues and my overall well being. His office staff are very helpful and responsive. It’s been a great experience. It’s evident that everyone in that office really cares about the patients and their quality of life.

Never in my life have I been to a worse medical practitioner. I have been dealing with thyroid issues for the last 6 months, and after having my symptoms dismissed by my PCP as "just what happens when you turn 30," I found a gynecologist, nurse practitioner, and different endocrinologist to validate that what I was going through was NOT normal, and were able to see that even though my lab results are within the "reference ranges" they are not OPTIMAL for a young, athletic woman of my age. I had made an appointment with Dr. Hosseini months in advance because he is the only endo in my area and practices through telehealth. Upon seeing me, he immediately told me my thyroid was normal, that my testosterone levels were normal (they are literally so low that the assay could barely register them) dismissed my symptoms, repeatedly asked me questions I had already given answers to which showed that he was not listening, and treated me like a number in line and offered no alternatives to why I could be feeling the way I do or how to proceed. I do not recommend him to anyone, and feel awful for the hundreds of women dealing with subclinical thyroid issues that are dismissed by doctors like this. Honestly despicable.

very knowledgeable
Excellent doctor I have had diabetes for years and have visited many endocrinologist. He was the first one who could manage my diabetes and bring my A1C down. His staff are nice too. His clinic manager, Val, is a wonderful person who could get me pri-authorization approved for my glucose sensors and insulin Homolog. Very caring

Unprofessional office and harried Dr.
He is a very caring Dr. He’s always in a huge rush and doesn’t listen well. His office is not well organized and return calls are iffy. He’s a very good man but needs someone to really be in charge of his office systems and staff.

Don't trust him
Very negative. After months of tests, he continued to just add additional medications, forcing my body into near renal failure. I ended up in the hospital for a week and all he could said, "it wasn't" his fault". Adverse drug interactions caused part of the problem. He should have checked.

Once again Dr. Hosseini has impressed me. After some tests and determination on his part, I feel like I have an honest assessment of my condition as well as a means of treating it. Thank you Dr. Hosseini!
