Our Mission

Our Approach

We believe in a holistic approach to mental health, focusing on individualized care that empowers you to renew your life and achieve optimal well-being through tailored strategies and compassionate support.

Joseph Impellizeri is a Board-Certified Psychiatric–Mental Health Nurse Practitioner with a broad and meaningful healthcare background, shaped by years at the patient bedside in emergency medicine and inpatient psychiatry. These early clinical experiences gave him firsthand insight into the powerful connection between mental and physical health and sparked a passion for providing care that treats the whole person—not just symptoms.

Today, Joseph primarily provides outpatient psychiatric care, with a focus on thoughtful medication management and collaborative, individualized treatment planning. He believes that emotional wellbeing, physical health, lifestyle habits, and life circumstances are deeply interconnected. With this in mind, he takes an integrated approach to care, working closely with patients to understand the full context of their experiences and helping them make informed decisions that support lasting mental and physical wellness.

In addition to his outpatient practice, Joseph continues to moonlight as a PMHNP at Yale New Haven Hospital, allowing him to remain engaged in the fast-paced, acute setting of inpatient psychiatry. This ongoing clinical involvement sharpens his ability to identify early warning signs, navigate complex presentations, and bring a well-rounded, comprehensive perspective to his outpatient work.

Above all, Joseph is committed to creating a compassionate and supportive environment where patients feel heard, respected, and empowered to pursue meaningful, sustainable change.
