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. The site may be a single practice, multispecialty practice, hospital based practice or a similar health care institution that has the infrastructure and staff to meet the requirements of the clinical trial protocol. We are not a “Site Management Organization” but rather the research division of a consortium of multi-specialty, multi-disciplinary medical groups comprised of 10 Neurology practices, a Pulmonary practice, a Cardiology practice and a community hospital; all throughout Broward County, Florida. We also work privately and exclusively with other medical groups that send their research patients to our facilities. Together, our medical groups provide care to more than 250,000 lives each year.

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 multitude of clinical indications. Our staff consists of 20 board certified physicians in Neurology, Cardiology, Pulmonary Disease, and Sleep Medicine; a team of three Neuro-Radiologists, a Neuro-Ophthalmologist, three PhD level Raters, and nine clinical research coordinators. In addition, our corporate administrative team includes our Executive Vice President who manages all business operations and our Director of Business Development & Medical Science Liaison who also provides support for clinical operations.

Infinity Clinical Research’s purpose 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 results.
