New Clinical and Administrative Leaders Named at Cohen Children’s Medical Center

NEW HYDE PARK, NY – Northwell Health today announced new leadership appointments for three key staff members at Cohen Children’s Medical Center.

In a move to further enhance pediatric clinical excellence in a complex and changing healthcare landscape, Charles Schleien, MD, has been appointed executive director of Cohen Children’s Medical Center.  He will also continue to serve as senior vice president and chair of the hospital’s pediatric service line – a position he has held since joining Northwell Health in 2012.

Dr. Schleien succeeds Kevin McGeachy as the hospital’s executive director. Mr. McGeachy, who led Cohen since 2012 and helped establish the children’s hospital as a leader in pediatric care in the New York area, was promoted to senior vice president of strategic alliances at Northwell Health. He will help lead Northwell’s efforts to explore new strategic alliances, affiliations and partnerships with other health care providers in the New York area and beyond.

Assisting Dr. Schleien in the oversight of Cohen will be Carolyn Quinn, RN, who has been promoted to deputy executive director, overseeing the operations of the children’s hospital. Ms. Quinn, who has held a variety of clinical and leadership roles at Cohen since joining the hospital in 1987, previously served as the associate executive director of patient care services and chief nursing executive.

Furthering the integration of the children’s hospital and service line, Jonathan Scheidt, has been named deputy executive director at Cohen and will take on financial and revenue cycle responsibilities for both the children’s hospital and service line, as well as continuing his service line operational role.  Mr. Scheidt, who joined Cohen in 2012, previously was vice president of the pediatrics service line.

Before joining Northwell, Dr. Schleien was executive vice chairman in the Department of Pediatrics at Columbia University College of Physicians & Surgeons.  He is past director of the Division of Pediatric Critical Care Medicine, which he founded upon his arrival at Columbia in 1999, and served as medical director of the pediatric intensive care unit at the Morgan Stanley Children’s Hospital of Columbia University.  Dr. Schleien also has served as director and fellowship director of pediatric critical care medicine at the University of Miami/Jackson Memorial Medical Center.

Dr. Schleien is chair and professor of pediatrics at the Hofstra Northwell School of Medicine.  He received a bachelor’s degree from the City University of New York’s Queen’s College, his medical degree from Mount Sinai School of Medicine and completed a pediatric residency at Texas Children’s Hospital, Baylor University Affiliated Hospitals in Houston; an anesthesia residency at The Johns Hopkins Hospital in Baltimore; and a fellowship in pediatric critical care medicine at The Johns Hopkins Hospital.  In 2008, Dr. Schleien received his MBA from Columbia University Graduate School of Business.

A member of the American Academy of Pediatrics, American Society of Anesthesiologists and the Society of Critical Care Medicine, Dr. Schleien is a longstanding member of the American Heart Association-Emergency Cardiovascular Committee, where he was instrumental in formulating the international guidelines in CPR.  His other clinical interests include neuroresuscitation, pediatric bioethics and pediatric administration.

With more than 28 years in the specialty of pediatrics, Ms. Quinn has held various clinical and administrative positions at Cohen Children’s Medical Center, including clinical nurse specialist of the pediatric intensive care unit, and several director and assistant director of clinical services in pediatrics.  Her clinical experience includes neonatal and pediatric critical care, critical transport, bone marrow transplant and medical/surgical nursing. 

In her role as chief nursing officer she oversaw strategic planning for nursing, clinical services and fiscal responsibility for the hospital’s largest cost center.  Heading the pediatric service line, she promoted pediatric patient safety through standardization of clinical competency, practice guidelines and care models.  Under her leadership, nursing quality at Cohen consistently outperformed national benchmarks in reducing infection rates, falls and other areas.

Ms. Quinn holds a MS in nursing from Molloy College and a BS in nursing from Adelphi University. She is a member of the Society of Critical Care Medicine, the American Association of Critical Care Nursing and the Emergency Nursing Association.  She received certification as an ECMO specialist by Georgetown University Hospital.

Mr. Scheidt’s areas of expertise include healthcare strategy and business development, finance, academic and research administration, quality improvement and hospital and outpatient operations.  At Cohen, Mr. Scheidt previously held the positions of assistant vice president of the pediatric service line and senior administrative director of the department of pediatrics.  Prior to joining the children’s hospital, Mr. Scheidt held administrative positions at Weill Cornell Medical College and New York Presbyterian Hospital.

Mr. Scheidt received his MBA from the New York Institute of Technology and BS in business administration from Albertus Magnus College in New Haven, CT.  He is also a certified paramedic, having worked as a paramedic for high risk infant transporter and a paramedic supervisor at Wyckoff Heights Medical Center in Brooklyn.
