Founder and Director

Kalen Dionne MD, PhD

Dr. Dionne was born and raised in the Eastern Plains of Colorado. He initially worked for his family’s construction business, but his career trajectory changed after attending Colorado’s Rural Health Scholars Program in early high school. He eventually became a magna cum laude graduate of Colorado College, where he completed his bachelor’s degree with distinction in Neuroscience. He then matriculated into the prestigious Medical Scientist Training Program (MSTP) at the University of Colorado, where he earned his Ph.D. in Neuroscience and his medical degree (M.D.). He went on to complete a rigorous neurology residency at Barnes-Jewish Hospital/Washington University in St. Louis. He then served as an attending neurologist at Washington University in St. Louis for several years before moving to Washington, Missouri to lead the Neurology section at Mercy Clinic. In 2025, he started his own practice (Dionne Neurology) in Washington, Missouri. Dr. Dionne and his family are ecstatic to be part of this charming community.

Julie and her husband Marc built their forever home on the family farm where they are raising their two boys.
