Atlantic Health names Dekker, Kloos and Ramsey to board, selects Ranger as new Vice Chair

A philanthropy president, a physician-turned-population-health executive and a Wall Street dealmaker join the health system's board

Atlantic Health’s board of trustees is adding expertise in philanthropy (Hans Dekker), population health (Dr. Thomas Kloos) and high-stakes dealmaking (Patrick Ramsey), it announced Tuesday.

The Morristown-based health system also announced it is naming Michael Ranger, who has served on the board since 2023, as a new Vice Chair.

Board Chair Laura Ann Kelly applauded the announcement.

“The Atlantic Health Board is delighted to welcome Hans, Tom and Patrick and thrilled that their considerable knowledge and experiences will now benefit patients across the communities we serve,” she said.

CEO Saad Ehtisham agreed.

“In today’s complex and rapidly evolving healthcare environment, good governance calls for diverse leadership perspectives and strong competencies in many different disciplines,” he said.

“We are fortunate to have the support of trustees who are as skilled and experienced as they are dedicated, with broad expertise and strong community ties to advance our mission.”
