Marchella Abbate, PMHNP-BC

Marchella is a board-certified psychiatric nurse practitioner who handles medication management for teens and adults, and she usually has the shortest wait on our psychiatric team.

Marchella joined the CMHS medication management team in 2026. She provides psychiatric evaluations and ongoing medication care for teens and adults, with a focus on ADHD, anxiety, and depression.

She works from the same chart as your therapist, so a medication change and a therapy plan stay in step instead of being pieced together after the fact. First visits are a conversation about what’s going on, not a checklist, and follow-ups are scheduled when you actually need them.

Before becoming a nurse practitioner, Marchella spent nearly four years as a psychiatric nurse on inpatient units at Yale New Haven Hospital and Mount Sinai Rehabilitation Hospital, caring for children, teens, and adults during their hardest stretches. That background shows in how she works: she is comfortable with complicated situations, and she coordinates closely with therapists instead of working in isolation. She earned her Master of Science in Nursing from Yale University and her Bachelor of Science in Nursing from Quinnipiac University.
