in Arcadia, CA |
She used to be our family doctor for many years but no longer. She does not order the appropriate tests or even follows up on procedures she has ordered. She is very passive. I prefer a more aggressive and assertive doctor.

TERRIBLE ! DO NOT waste your time with her. She see's you for 2 mins and barely listens to your symptoms. Completely misdiagnosis you and chuckles when you request to see a specialist. She's passive aggressive and joke of a doctor. She refused to order any tests. She makes excuses and says she doesn't want to get involved with the other Drs which as a primary health care physician she should get involved! STAY AWAY
