Karyn Kollonige, MSN, CRNP, PMHNP-BC, Psychiatric Nurse Practitioner
Karyn Kollonige (she/her) is a Psychiatric Nurse Practitioner who earned her Master of Science in Nursing (MSN) from La Salle University in 2023. Before pursuing graduate training, Karyn worked in the Heart and Vascular Surgical Intensive Care Unit at the Hospital of the University of Pennsylvania, where she developed expertise in managing acute crises, staying calm under pressure, and applying advanced medication management. Her experience also strengthened her skills in therapeutic communication, de-escalation techniques, trauma-informed care, and interdisciplinary collaboration—all of which shape her holistic approach to psychiatric care.
Following graduation, Karyn worked in private practice psychiatry, treating patients with a range of mental health diagnoses. She is now excited to rejoin Penn Medicine as a nurse practitioner, bringing her passion for compassionate, patient-centered care. Outside of work, Karyn enjoys spending time with her kids, partner, family, and friends. She loves to travel, with a particular passion for Disney.
