Going to this clinic was the worst decision in my life. I still suffer to this day, years later, from medical trauma. Dr. Best is childish, petty, and cruel, and his son, the office manager, is incompetent and cold. There are plenty of professional ketamine clinics across Chicagoland that will charge you a fraction of the cost and not force unnecessary vitamins through your IV (which costs extra). Dr. Best's office has garnered a reputation for traumatizing patients. When I have mentioned my experience here to other doctors and therapists they recognized his name with disdain. One of them even said he couldn't believe Best was still in practice. Wish I was joking. I went here from Oct 2020 to Aug 2021. I know the BS happening behind the scenes. Run.
