Ms. Treppendahl has been specializing in Headache Medicine since 2010, and she was awarded a Certificate of Added Qualification in Headache Medicine from the National Headache Foundation. She is passionate about improving treatment for headache disorders through clinical research and patient education, and she sponsors select patients to lobby for headache research funding in person in Washington, DC at the annual Headache on the Hill event. In addition to her national pharmaceutical speaker programs, Ms. Treppendahl and her colleague, Rebecca Adams, RN, MSN, FNP-C, have traveled the state of Mississippi to advocate for patient awareness and nursing education about headache disorders. (Community organizations, public and private schools and businesses are encouraged to contact The Headache Center to schedule a non-branded program about headache disorders and treatment.) 


In 2016, Ms. Treppendahl formed a clinical research department at The Headache Center to offer enrollment of subjects in multi-center, double blind, randomized, placebo controlled trials for new and reformulated drug therapies seeking FDA-approval. The Headache Center has enrolled patients in clinical trials for cluster headache treatment with Autonomic Technologie, migraine prevention treatment with Avanir Pharmaceuticals, and acute migraine treatment with Allergan, among others. More studies are planned with Avanir Pharmaceuticals, Gammacore and Supernus. (Further information about current clinical trials can be accessed on our Clinical Trials page. Care related to study medications and devices is free of charge and compensation for time and travel is provided.)
