We’re pleased to welcome Kathleen Killeen, MSW, MPA, LICSW, MLDAC, QCSW, CAADC, ACSW, CMT, to the Cottage Hospital team!
Kathleen brings an incredible 45 years of experience in the field of social work, with a career spanning a wide variety of clinical and community settings. Her experience includes work within the New Jersey prison system, Philadelphia methadone clinics, outpatient and inpatient psychiatric care, gerontology, burn units, child welfare and abuse investigations, private practice, head trauma care, and Assertive Community Treatment (ACT) teams.
Kathleen also has extensive experience in substance use treatment and holds dual licensure in clinical social work and drug and alcohol counseling across multiple states. In 2015, she combined two of her passions—behavioral health and music—by creating a music therapy program at a Philadelphia methadone clinic. The program was featured in Social Work Today in an article titled “Recovery Sings.”
Music is a big part of her life professionally and outside of her work—she plays multiple string instruments, and considers voice and guitar her favorites. Fun Fact: she owns more than 30 guitars!
With decades of diverse experience and a passion for helping others, Kathleen brings a wealth of knowledge to our team and the patients we serve.
Please join us in giving Kathleen a warm welcome to Cottage Hospital! 💙
