Center Overview

Infinity Clinical Research provides clinical trial related services to pharmaceutical companies, contract research organizations (CROs), biotechnology companies, medical device companies and clinical sites in need of partnering capabilities for ancillary services. We are not a "Site Management Organization" but rather the research division of a consortium of signle and multi-specialty, multi-disciplinary medical practices including Neurology, Internal Medicine, and Pulmonary disease, all throughout Broward County, Florida. Together, our medical groups provide care to more than 250,000 lives each year. We also work privately and exclusively with other medical groups that refer their patients to participate in our various enrolling trials.

Infinity Clinical Research has a qualified and experienced team of clinical research professionals who understand the intricacies of conducting clinical trials. Our experience with the entire process, from feasibility to site closeout, enables us to ensure timely and effective delivery at every stage of a trial. Our dedicated research team is comprised of highly skilled research professionals with many years of experience in all phases of trials and in a myriad of clinical indications. Our staff consists of board certified physicians in Neurology, Internal Medicine, Pulmonary Disease, and Sleep Medicine; a team of Neuro-Radiologists, a Neuro-Ophthalmologist, PhD level Raters, and Certified Clinical Research Coordinators. In addition, our corporate administrative team includes our Executive Vice President who manages all business operations, our Director of Business Development & Medical Science Liaison who also provides oversight for regulatory compliance, and our Administrative Coordinator who supports both the Vice President and Director of Business Development.

Infinity Clinical Research's goal is to provide benchmark standards in research practice but also understand the governing regulations regarding clinical trials; thereby earning Infinity Clinical Research recognition as a company that provides our customers with excellent service, responsiveness and quality results.
