Neurologist and clinical neurophysiologist Tara Quesnell, DO practices in Carlsbad at The Neurology Center of Southern California on Hidden Valley Road in the 92011 corridor. A Kansas City University of Medicine and Biosciences graduate (DO, 2010) who completed neurology residency and a clinical neurophysiology fellowship at the University of Kansas, she evaluates neuromuscular conditions using EMG and nerve conduction studies that may integrate with functional-medicine assessments at Quantum Functional Medicine on El Camino Real. Board-certified in both neurology and clinical neurophysiology by the American Board of Psychiatry and Neurology, she joined the Neurology Center in 2016 after serving as a clinical assistant professor at the University of Kansas. Her caseload spans headache classification, peripheral neuropathy workups, and myasthenia gravis monitoring, with annual visual-field and fundoscopic coordination routed through optometry teams at Eye Style Optometry. Her highest-complexity diagnostic studies involve repetitive nerve stimulation protocols for neuromuscular junction disorders, single-fiber EMG for myasthenia gravis confirmation, and quantitative sudomotor axon reflex testing for small-fiber neuropathy evaluation.
