Dr. Sandra Van Gundy, EdD
Vice President of Quality, Risk and Patient Experience

A seasoned Registered Nurse, Dr. Sandra Van Gundy spent 12 years rotating throughout clinical roles before making the jump to academia where she was an Associate Professor of Nursing with a focus on quality, patient safety, and health at Plymouth State University. “As an advocate for population health, my work centered on health needs of populations across the world, from Latin America to China, treating both chronic and acute illness and monitoring determinants of health,” said Van Gundy.

Despite years in healthcare as a practicing clinician and educator, Van Gundy’s most enlightening experience wasn’t as a nurse or professor, but rather as a patient, at the receiving end of the care she spent a lifetime practicing.

“As a cancer survivor, I realize being a patient was a gift as a practitioner, because I realized that despite efforts to empathize with the patient, really have no idea what our patients are going through,” said Van Gundy. “There was a tremendous empathy gap, caregivers were often challenged to successfully put themselves in their patient shoes and were developing plans of care that were not able to meet patient’s individualized needs.” Following recovery, Van Gundy came to the conclusion that her experience was an opportunity to influence healthcare system design so it balances evidence-based decision making with unique needs of patients in order to provide those we serve with a better patient experience.

As the hospital’s leader for quality and patient experience, Van Gundy believes that her experience as both a patient and practitioner has uniquely equipped her to optimize patients’ experiences at Nantucket Cottage Hospital, while leading the organization through a pivotal period for healthcare providers across the nation.
