She is an advocate for protocol-driven care, quality improvement initiatives, and interdisciplinary education. Her work as SICU Medical Director has allowed her to successfully lead a high-performing ICU, implement impactful clinical processes, and mentor the next generation of surgical intensivists and acute care surgeons.

Originally from Puerto Rico, Dr. Murray completed her medical education and general surgery residency at the University of Puerto Rico School of Medicine in 2013. She later served as a Clinical Assistant Professor there before pursuing fellowships in trauma and surgical critical care at the University of Florida. Since completing her training in 2018, she has remained deeply committed to academic surgery, critical care, and service to the veteran population.

Dr. Murray is passionate about surgical education and mentoring. She takes pride in guiding medical students, residents, and fellows through the intense, rewarding environment of acute care and critical care surgery.
