I am losing one of the best doctors on my team. I wish I had known before my last visit that it would be my last. I would have wished Dr Fernandez all the best in life because she changed my life. So sorry and sad to see her leave the practice.

NO CALL BACK. finally she called back. no apologies other than too busy. Felt very dismissed and the phone call was completely argumentative. Picking up records and finding new compassionate and caring Dr

Dr. Fernandez is obviously intelligent and knowledgeable. But I found our interactions to be unpleasant at worst & disconnected at best. She seemed more interested in her notes than in me, interrupted me often, & was almost 'military' in style. I never quite sensed she saw me as a human but more as numbers or a file. She'd do well to connect more deeply with patients. She didn't like my feedback & so had her nurse tell me to find another doctor. To me, that's not a doctor who cares about me. :(

Talked over me entire visit. Said I didn't need the meds another Dr. prescribed. Refused to listen to me. No test results, meant no meds for 3 wks. Looked at my thyroid and said OMG!!!! I said what's the matter? I asked again if something was wrong. She said well it's not good. Then proceeded to tell me how people with Hashimotos get thyroid cancer. Scared me to death. Then screamed at me on phone. PS: Sonogram confirmed NO cancer. Worst Dr. I ever seen!!!!!!!!!!
