About

Us

GW Research is a growing Clinical Research facility located next to our parent Gastroenterology Medical Practice. With over 20 years of existence, we have conducted hundreds of clinical trials and collaborated with top clinical and pharmaceutical institutions.

Our Principal Investigators are board-certified in Gastroenterology and serve as attending physicians in neighboring institutions such as Scripps and Sharp healthcare.

More Info about GW Research

Dr. Gregory Wiener serves as our President and Principal Investigator. Along with leading his private medical practice, he maintains collaboration with diverse academic institutions. His personal interest in new medical developments leads to close supervision and excellence in all our operations.

At GW Research there is always an investigator present to attend to patient needs, meet with coordinators, and tackle daily study issues. All patients are given direct access to our coordinators in charge of their study.

We have two clinical sub-investigators who have been working with the principal investigator for years and also have large clinical practices, where most of the patients for studies are recruited.

GW Research is under constant supervision of Central Review Boards and diverse scientific advisory committees and has no local obstacles to a rapid, easy, and efficient implementation of a study.

All budget negotiations and major decisions are managed by the Principal Investigator (PI), and there is no intermediate organization that would compromise the direct access of Contract Research Organization (CRO) and the physicians that are part of this organization.
