In Memoriam: Dr. Andre Petrossian
-
It is with deep sadness that we remember Dr. Petrossian, a valued member of our team who passed away unexpectedly in 2024. Dr. Petrossian was a licensed psychologist in California, earning his Psy.D. from California Lutheran University. His research on the impact of attention-deficit/hyperactivity disorder on concussion assessment scores in NCAA athletes and United States military cadets exemplified his commitment to advancing our understanding of complex neuropsychological issues.
As a dedicated lecturer at California Lutheran University, Dr. Petrossian shared his knowledge and passion for neuropsychology with future professionals. His contributions to our team and the broader community were immense, and his warmth, empathy, and professionalism touched the lives of many.
Dr. Petrossian will be deeply missed, but his legacy of care and dedication will continue to inspire us all.
