This erratic woman has no business being in patient care. She is better suited to a lab where it is just her and the equipment. I have been astonished by the immensely deficient attention to environment, common rules of etiquette (how do you lay hands on a patient without first greeting them?? talking over them???), any degree of professionalism, reasonable treatment of her hard-working staff, etc. She has mixed up my meds, lost blood work, not revealed two serious health conditions to me.

Worst doctor ever. I was hospitalized for Graves' disease and when I asked for a referral to an endocrinologist she refused! Said I needed to come in to see her first. Every time you go you end up waiting 2 hours for her to spend 5 minutes with you and you can tell even understand what she's saying. Finally switched doctors and couldn't be happier.

Very unprofessional. Discusses patients info in direct listening range to entire office. Berates her nurses and patients. Overbooks and over 2 hour wait for 3 minute visit where you are not allowed to speak.

Dr Ni is very rude and disrespectful. I wouldn't recommend her to my cat.

I wish I could give her half star if they have this option. This DOCTOR doesn't have any morality, I didn't understand how she could be a DOCTOR. It will humiliate the WORD. NO ANY RESPECT, NO PROFESSIONAL. NEVER EVER WENT THERE ANYMORE IN MY REST MY LIFE. CRAZY HUMBENBEING.

I came to the United States have never seen such a bad attitude like her doctor, because my English is not good, she also impatient, impatience, racial discrimination, I am a patient, not a thought criminal. She violated me privacy, and an appointment time, she was not in the office, so we had to wait 40 minutes
