“As a Psychiatric Mental Health Nurse Practitioner, it is my goal to advocate for people who feel like they have been looked over or may have lost hope.”

Jennifer Joseph, APRN, PMHNP

Psychiatric Mental Health Nurse Practitioner

Jennifer Joseph is a Psychiatric Nurse Practitioner at On Demand Counseling. Jennifer joined our team in July 2020 and currently practices at both our Austintown and East Liverpool locations.

In her practice, Jennifer approaches each of her patients with empathy and compassion to provide a non-judgemental, safe space to discuss their needs and mental health concerns. Jennifer takes her practice one step further by providing access to resources and various services, as needed, to ensure clients’ mental, physical and social needs are cared for.

Jennifer is certified to treat patients ages six and older who are struggling with various mental health concerns. In fact, Jennifer specializes in trauma and its correlations to our physical and emotional well-being. Aside from trauma, Jennifer treats those with depression, anxiety, bipolar disorder, schizophrenia, obsessive-compulsive disorder and more.

“My goal is to treat all people with respect and equality,” says Jennifer. “I provide a safe, judgment-free zone and take the time to listen. I encourage clients to take an active role in their treatment by providing education and open dialogue.”
