Worst psychiatrist I have ever seen in my entire life. She is extremely judgmental. She called me a pill popper because I told her I was experiencing really bad panic attacks. She kept getting my age wrong? I was 23 and she kept mistaking my age for 17. The medication she prescribed me induced my panic attacks and she accused me of lying. Also she saw my sister while seeing me which I don’t even think is legal. Years later I took a test to see how I metabolize certain meds and every single one she prescribed me appeared as “not recommended.” Note: I also have really severe insomnia and she gave me a med that didn’t work for me at all accused me of lying when I explained that to her. I also have adhd, diagnoses from a young age, she had papers proving so. Still refused to work with me. Also I must add that the therapist she recommended wasn’t even licensed? He was a life coach. I had been going through a horrible time in my life and this woman made it worse. Mind you, I have never
