May, 2017: In July 2016, WRN re-located to a new clinical research unit. This 12,000-square-foot site with 24 beds was purpose-built for subjects participating in clinical trials. The site is equipped with PSG for sleep disorders, can conduct complex studies with serial PK draws and other special procedures. Under the direction of Dr. Fayz Hudefi, the site continues to build on its experience in psychiatry and neurology while expanding into new therapeutic areas. Over the past year, WRN has been awarded/conducted studies in opioid withdrawal, Alzheimer’s disease, essential tremors, Post-Traumatic Stress Disorder, pediatric/adolescent Tourette’s Syndrome, migraine and Complex Regional Pain Syndrome. Dr. Robert Billingsley has joined WRN with extensive experience in psychiatric indications, specifically Schizophrenia and PTSD. He will serve as a Principal Investigator and rater. WRN is planning for further expansion which  will include a dedicated indoor smoking room and a 12-bed CPU designed for special populations
