The best psychiatrist I’ve had! Very calm and great at what he does! I always recommend him

He didn't disclose a major diagnosis. He radiates apathy. He barely talks and straight up doesn't listen. Treatment-wise he does the absolute bare minimum. He terminated me because I was late to an appointment and I couldn't get a referral, so I went without a psychiatrist for almost two years. Completely ignorant of other cultures. Koller's a rotten psychiatrist who belongs in another decade.

STAY AWAY! Dr. not at all up to speed on current research. Poor bedside manner - does not appear to be caring or empathetic at all. Apathetic attitude and neglected to do comprehensive evaluation which lead to poor treatment. When I had an issue after the appt. he refused to speak with me about it and had his assistant tell us to go to an ER to get care although it was not an emergency. Drive by Psychiatry which gives the profession a bad name.

Koller is OK but he isn't very good about being an advocate for you and tends to be a little too laid back on the treatment plan. Psychiatrists often have the hard job of telling patients hard news twho aren't the most receptive given mental health and cognitive behavior tendencies, things they might not want to hear, and instead of doing this he tends to listen, nod, and then say see you in 3 months. He doesn't really address issues or confront issues head-on.
