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 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.
