Will oversee establishment of advanced clinical services as East End’s largest hospital becomes a Regional Medical Center

RIVERHEAD, NY - Peconic Bay Medical Center has named Susan Somerville, RN, to the newly created position of vice president for clinical transformation.  She will oversee the implementation of advanced clinical services as Peconic Bay Medical Center and Northwell Health continue to establish the East End’s largest, most comprehensive regional medical center.

SusanSomerville_cropped.jpgMs. Somerville most recently served as president of Mount Sinai Beth Israel Hospital in Manhattan. Previously, she held several key leadership positions within Northwell Health, including executive director of North Shore University Hospital in Manhasset.

“We are pleased and excited to have someone of Ms. Somerville’s stature join us as the medical center rapidly evolves into a regional hospital,” said Andrew J. Mitchell, FACHE, president and CEO of Peconic Bay Medical Center. 

“Susan Somerville is a fantastic addition to the Eastern Region team for Northwell Health.  We are thrilled to have her back at Northwell to help shape and guide the next era of health care for the East End of Long Island.  Peconic Bay Medical Center is poised for tremendous growth and I look forward to working with the leadership at the medical center to meet the health care needs of this community,” said Kevin Beiner, senior vice president and eastern regional executive director at Northwell Health. 

“I am thrilled at the opportunity to come home to Long Island and put my skills to work bringing top-notch health care services to the East End,” said Ms. Somerville. “The need for advanced clinical programs is a tremendous opportunity, and I am looking forward to it.”

Ms. Somerville began her career as a registered nurse, specializing in cardiac and critical care nursing. She received her Bachelor of Science degree from St. Joseph's College, her RN degree from Catholic Medical Center of Brooklyn and Queens, and her masters degree in health administration from Hofstra University. She also attended the Wharton Fellows Program in Management for Nurse Executives at the University of Pennsylvania.

One of Ms. Somerville’s first responsibilities will be the construction and development of PBMC’s new $60 million Corey Critical Care Pavilion that will house the East End’s most comprehensive advanced cardiac program, the Kanas Regional Heart Center.

“Susan Somerville is a strong choice to bring world-class cardiology services to the East End,” said Stanley Katz, MD, chair and professor of cardiology at the Hofstra Northwell School of Medicine, and a practicing cardiologist with East End Cardiology Associates, Eastern Suffolk’s leading cardiology practice. A pioneer in bringing interventional cardiology services to Long Island, Dr. Katz was instrumental in the planning and design of Peconic Bay Medical Center’s new Cardiac Cath Labs.

Ms. Somerville joins Jean Cacciabaudo, MD, Peconic Bay’s new medical director, and Stanley Katz, MD, a nationally renowned interventional cardiologist and new chair of cardiology at PBMC.  Each will play a key clinical role in Peconic Bay Medical Center’s future growth and expansion including the recently designated Level III Trauma Center, the North Fork’s only  New York State designated primary stroke center, and the just approved establishment of Peconic Bay Medical Center’s new Corey Critical Care Pavilion.  This tower will bring life-saving cardiac catheterization and electrophysiology labs as well as a new rooftop helipad to serve Northwell’s singularly unique Skyhealth ICU-level helicopter emergency transport program.
