After leaving the NIH, he formed his own clinical trials research organization, first in conjunction with area hospitals, and then as a free-standing inpatient and outpatient clinical research organization now known as CBH Health. Since then he has conducted over 300 Phase I-IV clinical trials and has participated in many of the important advances in pharmacotherapy of schizophrenia and other brain disorders.
