Discover Diedre’s career journey in nursing leadership at Northwell Health

Meet Diedre Morrissey, who grew her career from staff nurse to nurse manager at Northwell Health’s Long Island Jewish Medical Center (LIJMC). Throughout her time at Northwell, Diedre has been grateful for the tools and experiences that have helped her grow her career.

Diedre began her career with us in 2016 as a staff registered nurse at LIJMC. In this role, she was responsible for coordinating collaborative care, performing assessments, forming nursing diagnoses and planning, implementing, and evaluating interventions. She assessed patients, administered prescribed treatments by physicians, and provided direct patient care and education for patients and their families. After two years in this role, Diedre’s experience led her to her next position as an assistant nurse manager for her medical-surgical unit while she also covered other medical-surgical units at LIJMC. As an assistant nurse manager, Diedre maintained clinical expertise and competencies to provide patient care, while she also managed staff, assisted with staff education and unit projects. During her time in this role, Diedre took part in Northwell’s tuition reimbursement program and in 2019 she earned her Master of Science in Nursing (MSN) with a specialization in family nurse practitioner (FNP). One year after beginning her master’s degree program, Diedre started her current role as a nurse manager in patient care at LIJMC. Today, she is responsible for leading and supervising clinical staff, as well as overseeing hiring, onboarding, training, and performance evaluations for her team members to ensure excellence in patient care and team development.

Throughout her career, Diedre was surrounded by colleagues and other leaders who have always motivated, supported, and encouraged her personal and professional growth. “Northwell has made a world of difference in my career journey through access to leadership training, mentorship and tuition reimbursement programs,” said Diedre. One of the mentorship programs she recalls fondly was through Northwell’s Institute for Nursing. Diedre was a mentee while she was stepping into her role as a nurse manager and adjusting to this new role. She was paired with another nurse manager who contributed positively to Diedre’s development and helped her navigate the difference between leading and managing. She also offered Diedre advice that reminds her to see, hear and appreciate her team for all that they do. “I attribute a lot of my success to listening to the advice of my mentors, allowing them to lead and guide me in the right direction when I need it,” said Diedre. “Having consistent support from those who’ve had similar experiences made a huge impact on my career journey,” reflected Diedre.
