Karen Leinhauser, MSN, APRN, PMHNP-BC

Child, Adolescent & Adult Psychiatry

“We talk about courage like it’s loud, like it always stands tall. But some days, courage is soft. It’s you, showing up to a world that feels too heavy, and whispering… maybe healing starts here.”

Karen Leinhauser is a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) providing compassionate, evidence-based care across the lifespan. She is licensed in Pennsylvania, New Jersey, and Delaware, and integrates psychotherapy and psychopharmacology to help individuals move toward greater wellness, connection, and meaning.

Karen works with children, adolescents, and young adults across a wide range of needs, integrating clinical insight with empathy and precision in care. She specializes in supporting individuals with developmental challenges, particularly autism spectrum disorder, ADHD and intellectual disabilities, taking a strengths-based approach that recognizes each person’s identity, background, and lived experience. She also has extensive experience treating complex co-occurring mental health conditions, including anxiety, depression, obsessive-compulsive disorder (OCD), bipolar disorder, and schizophrenia spectrum disorders, including First Episode Psychosis.

Guided by humility and the principle of thoughtful prescribing, Karen approaches medication management as a collaborative process between provider and patient building a therapeutic alliance grounded in trust, empathy, and deep respect for autonomy. Drawing from both her clinical expertise and her lived experience as the parent of an adult son with autism, Karen brings an authentic understanding of neurodevelopmental and behavioral complexity to her work. She believes that every person deserves care that affirms their worth and supports their pursuit of wellness, belonging, and purpose.

On a personal note, Karen considers her family her greatest accomplishment. Raising seven deeply individual children has shaped the way she practices—teaching her patience, perspective, resilience, and a profound appreciation for the beauty and challenges of growing minds. She brings that real-world insight into her clinical work, meeting every individual with empathy that is both professional and profoundly human.
