  • Integrity : every coordinator and the PI place the volunteer first above everything else. We are responsible for answering all of the patient’s questions and concerns and are there whenever the patient has a problem.
  • Service : We pride ourselves on having volunteers that return for other studies and refer other volunteers. We think of ourselves as a family and treat patients as we would like to be treated.
  • Dedication : Every staff member at Aventiv is committed to giving 100% to every study and volunteer. We strive to be number one in every aspect of research and to help within the medical community.
