About us
A research site built around the people in the chair
Precise Research Centers is a clinical research site and mental health clinic based in Flowood, Mississippi, serving the Jackson metro area and surrounding communities. It was founded by industry veteran Joseph Kwentus, MD.
Participants at Precise Research Centers receive access to investigational treatments for a wide range of psychiatric, neurological, and medical conditions, under the attentive care of an experienced clinical trial staff.
Dr. Kwentus and his team research medications across all phases of development, and have collaborated with leading pharmaceutical companies and universities to evaluate the safety and efficacy of new medications and devices.
Our approach is deliberately unhurried: protocols are explained in plain language, consent is never rushed, and every study is conducted under independent IRB oversight and applicable federal regulations for the protection of human subjects.
