I attribute my success to steadily growing within healthcare, starting as a nursing assistant in 1993 and learning from every role along the way. Leading teams at Northwell Health—especially during challenges like COVID-19—has taught me that strong leadership, clear communication, and a dedicated team are key to achieving exceptional patient care and operational excellence.

The best career advice I’ve ever received is to never stop learning. Continuously growing—whether through formal education, professional development, or personal hobbies—keeps you inspired, creative, and connected.
What advice would you give to young women entering your industry?
My advice to young women entering healthcare is to find a leader you admire and learn everything you can from them. Leadership isn’t about the title—it’s about showing up for your team, listening, and staying grounded in purpose. The strongest leaders I know are the most humble.
What values are most important to you in your work and personal life?
The values most important to me are dedication, integrity, and empathy.
