Heartland Research Associates was started in 1991 by physicians Dr. Terry Poling, Dr. Terry Klein, and Dr. Thomas Klein, in their family practice in Wichita, Kansas. Their first research study was a sinusitis trial. The trial proved to be beneficial to their patients care. The decision was made to become investigators in another study, a flu treatment study. These first studies spurred the physician’s excitement further in research; they saw direct results benefiting patients and the patients enjoyed being a part of the research process! Dr. Tracy Klein joined Heartland Research Associates in 2001. These four physicians’ decided to continue the commitment to progress patient care and revolutionize patient’s health, by conducting research trials that will improve medicines and a patient’s treatment. Heartland Research Associates mission is to provide quality medical care to our research participants, with a commitment to accurate and precise data for our sponsors. The resulting strong relationship we have with our patients, aids in successful recruitment, compliance, and retention. This relationship has allowed Heartland Research Associates to encompass five sites, four medical directors, and over 60 employees providing high quality care to our patients while advancing medicine.
