JESSICA JACOB SABU, MSN, RN, CCRN
Psychiatric mental health nurse practitioner
I am a certified critical care registered nurse. I have worked in neurocritical care and post anesthesia care units, as well as in substance abuse clinics. Psychiatry was always a field of interest to me as I felt drawn to patients suffering from mental health conditions. I was also on the frontlines during the COVID-19 pandemic and witnessed burnout among providers, as well as heightened stress/anxiety/depression in patients and their families. This further grew my interest to pursue becoming a Psychiatric Nurse Practitioner since there was such a great need to fill the gap of mental health providers. I have a profound interest in working with young adults and children, and in my spare time I love to hang out with my family and friends, travel, and learn about new things.

I’m Brittany, a Licensed Social Worker with over eight years of experience working with children, adolescents, adults, and families navigate mental health challenges.
