Shelley Peery, PhD is the founder and executive director at San Francisco Neuropsychology, PC (SFN), an institute for cross cultural neuropsychological assessment across the lifespan. Dr. Peery maintains clinical and forensic caseloads, teaches, and collaborates on SFN research. A graduate of the Neuropsychology subprogram at City University of New York, Dr. Peery is bilingual in Spanish and evaluates individuals of all languages. She established SFN in 2009 to provide culturally competent evaluations and training. SFN staff train post-doctoral fellows and a class of about 5 practicum students.

Her predoctoral internship with an emphasis on Geropsychology was at the Rocky Mountain Regional Medical VA center specializing in dementia care for which she is a certified VA Reach provider. She completed her postdoctoral fellowship at the University of New Mexico, which is part of The Association of Postdoctoral Programs in Clinical Neuropsychology, with training in outpatient neuropsychological assessment of adults from a wide referral base including neurology, psychiatry, neurosurgery, and internal medicine.  In addition, she obtained pediatric neuropsychological training experiences for differential diagnoses of Attention-Deficit/Hyperactivity Disorder, Specific Learning Disabilities, Intellectual Disability, and emotional conditions in children.  

Dr. DeVaughn has a strong training background in the assessment and management of older adults and neurodegenerative disease. Her published research focused on memory patterns across neurodegenerative disease including Alzheimer’s disease, semantic dementia, Parkinson’s disease, and older adults with HIV.   

Currently, Dr. DeVaughn specializes in the assessment of surgical candidates for deep brain stimulation. In addition, she is a consultant for a level 4 Epilepsy Center at the University of New Mexico Hospital where she conducts presurgical evaluations of patients with epilepsy. She performs clinical brain fMRI studies for lateralization of language dominance in epilepsy patients and post-operative risk assessment of language and motor functions in the setting of resective surgeries in patients with intracranial brain tumors. At the University of New Mexico, she also monitors motor and language functioning in tumor patients undergoing awake brain surgery.  

Dr. DeVaughn is a member of the American Academy of Clinical Neuropsychology and American Society of Functional Neuroradiology.
