About Clinvest

Clinvest is a research organization dedicated to the advancement of medicine and health management through clinical research. Founded by Dr. Roger Cady in 1996, Clinvest began as a research office associated with a small, independent primary care and headache specialty clinic located in Springfield, Missouri. Dr. Cady’s vision was to explore concepts sparked by information gathered in a clinical setting. Combining his clinical expertise in headache and his understanding of the value of patient reporting, Clinvest was formed. The results of many of those early migraine trials have revolutionized our understanding and treatment of migraine today.
