Dr. Kassavetis is a neurologist specializing in movement disorders, including tremor, parkinsonism, dystonia, and myoclonus. He is an expert in ultrasound- and electromyography (EMG)-guided botulinum neurotoxin injections.

Dr. Kassavetis is a member of the multidisciplinary deep brain stimulation (DBS) team at the University of Utah in Salt Lake City, Utah, and performs preoperative assessment, intraoperative monitoring, and postoperative DBS programming for patients with Parkinson’s disease, essential tremor, dystonia, and other movement disorders. He also evaluates patients with movement disorders for MRI-guided focused ultrasound ablation therapy.

Dr. Kassavetis completed medical school at the University of Athens, Greece. Subsequently, he completed his Master of Science in clinical neurology and doctorate in neuroscience at the UCL, Queen Square, Institute of Neurology in London, England, as well as a six-month scholarship program at Johns Hopkins University in Baltimore, Maryland.

For his PhD, Dr. Kassavetis studied human motor control using techniques such as noninvasive brain stimulation (transcranial magnetic stimulation and transcranial direct current stimulation), EMG, and electroencephalography. After obtaining his PhD, he completed a residency in neurology at Boston University and a subspecialty fellowship in movement disorders at the National Institutes of Health, Bethesda, Maryland, under the mentorship of Dr. Mark Hallett. During his fellowship he used ultrasound for neurotoxin guided injections, under the mentorship of Dr Katherine Alter. In 2021, he joined the faculty of the University of Utah as an assistant professor of neurology.
