Dr. Calegan is a native of South Louisiana. He graduated valedictorian from Woodlawn High School in Baton Rouge, and magna cum laude from Louisiana State University with a degree in Petroleum Engineering.  Dr. Calegan earned his medical degree from Tulane University with honors (Alpha Omega Alpha honor society) in 2001 before leaving Louisiana to complete his neurology residency at the University of Alabama-Birmingham Medical Center where he served as Chief Resident in Neurology from 2004-2005.  Before returning home to practice in Baton Rouge, Dr. Calegan completed a fellowship in Movement Disorders with a heavy emphasis on the treatment of Parkinson’s Disease and cutting-edge treatment options for movement disorders including Deep Brain Stimulation (DBS) and Botulinum Toxin Injection (Botox).  Dr Calegan has extensive experience injecting botulinum toxins for many neurologic conditions including Cervical Dystonia, Blepharospasm, Hemifacial Spasm, Focal Dystonia, Spasticity, Chronic Migraine, and Sialorrhea (drooling). 

Dr. Calegan joined The NeuroMedical Center in 2006, and alongside neurosurgeon Dr. Paul Waguespack, developed Baton Rouge’s first Deep Brain Stimulation Center in 2007 to treat patients with Parkinson’s Disease, essential tremor, and dystonia.

Dr Calegan treats all neurologic conditions and is actively engaged in clinical research. He has served as the primary investigator for several clinical trials at The NeuroMedical Center.  

Alongside state-of-the-art neurologic care, Dr Calegan emphasizes what he calls “the 3 pillars of health – diet/nutrition, exercise, and sleep” in order to unlock the natural healing powers of the human body.  He believes the combination of modern medicine with optimal diet, exercise, and sleep can result in better outcomes than what modern medicine alone can provide.  This is especially important when treating the devastating effects of neurologic disease. 

Dr. Calegan is an active member of several professional organizations including the American Academy of Neurology and the Movement Disorder Society.
