Our MDs average over 25 years of clinical research experience and our senior staff average over 20 years of clinical research experience. We conduct Phase 1-3 studies and have separate outpatient and inpatient units on site. Our research facility grew out of Dr. Weinstein’s endocrinology practice with an emphasis on diabetes. Diabetes remains at the core of our research, but we have expanded into many different therapeutic areas involving both medications and devices.
