Founded in Glendale, California MEIRxRS is a trusted partner in the bioscience industry, providing services and solutions that are sustainable and adaptable to your needs.

Story of MEIRxRS

In 1992 in Glendale, California, founder Rosemarie Christopher established Med Ex International (the MEI in MEIRxRS) to recruit and place top-performing professionals in the life science industry. After helping many clients, MEI expanded in 2005 to not only recruit professionals, but provide research staffing solutions, adding on the “RxRS” to the company’s name. This division of the company was established to assist companies in maintaining tight control of their late-stage trials, studies and projects, from budget to the timely delivery of data.

Six years later, MEIRxRS founded Rx Services in 2011, dedicated to management solutions that keep your company’s projects running on-time and on-budget. MEIRxRS has the unique ability to pivot quickly, which means that whatever issues your company faces, we can respond timely and effectively.

Today, MEIRxRS continues to be the partner of choice for the government-regulated companies, as we provide quality solutions that help to move America’s economy forward.
