About
At Greenlight Neurology, Dr. Konstantin Karmazin delivers board-certified neurological care entirely by video. The practice serves patients across ten states: Arizona, California, Colorado, Idaho, Illinois, Nebraska, Pennsylvania, Texas, Utah, and Washington.
Dr. Karmazin built the practice around a straightforward belief: great care starts with listening without judgment. New patient visits run a full hour. That time allows for thorough history-taking, a virtual neurological exam, and a custom treatment plan. The practice covers a wide clinical range, from migraine and epilepsy to dementia, movement disorders, concussion recovery, sleep disorders, Long COVID, and complex undiagnosed conditions. Patients book directly without a referral. Dr. Karmazin coordinates local imaging and lab work near each patient and sends prescriptions to their nearest pharmacy.
