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.

Social IQ near zero. Useless doctor @
This doctor doesn't want to be there, listen, help, and be someone trustworthy. Total waste of time.

He is a very thorough and professional doctor. I trust his medical recommendations for me because he is very knowledgible. He is a hidden gem in health care. Additionally, his office staff are kind and helpful all the times. They made me feel very comfortable. Thank you.

one star is too much for him.
Horrible doctor, horrible experience. Should've read all the other reviews, before we wasted our time with him. He is Rude, Unprofessional and indifferent to the patient needs. He has terrible bedside manners and was rushed during the appointment as if he was late for his lunch and could not get us out of his office fast enough. He would get 0 stars if that was available.

Horrible doctor. He does not care for your needs and disrespects you. He rushes the appointment and makes your feel low of yourself. Save yourself the time and don’t go to him. Shocked he is even a doctor, worst patient care I have ever seen.

I have never been so disrespected and belittled by a doctor in my life. He was so combative I was in shock and speechless. I will start with the fact that he was 20 minutes late and appeared very irritable. He shrugged his shoulders and dismissed my concern for having Covid. I told him no home tests are available at my local pharmacy. He then rolled his eyes and said “I just got one a month ago from a drug store”. Alluding that I’m wasting his time and coming off as visibly irritated and impatient. He was very rushed and aggressively cutting me off throughout the visit in a very unprofessional manner. No one deserves to be treated this way when seeking care. I would never expect this type of behavior from a UCLA doctor.

Rude
Rude, dismissive, and makes it feel like you’re wasting his time with your stupid questions. Any question I had was immediately shot down and he laughed like my questions were ignorant.

Rude, unprofessional and headstrong attitude
He does not give us a chance to explain. He lacks bedside manners and very rude with patients. He is so headstrong that he knows the best and does not care what we want. Regret not to check his reviews before I scheduled an appointment with him.

Dr. Yun was on time, respectful, has a nice bedside manner, and most importantly, correct in his diagnosis. He was the second doctor I had consulted on this particular issue and after seeing him, it was cleared up in a few days. Since then, I have made him my primary physician.
