Dr. Gustavo Alva is the director of clinical research and he has served as a principal investigator for many years conducting investigation in a myriad of neuropsychiatric conditions; Alzheimer's and other dementias, depression, anxiety disorders, bipolar disorder and psychotic conditions as well as multiple others.
