The Queen’s Health System Announces Promotions of Three System Leaders


To better meet the current and future needs of patients and communities in today’s rapidly changing health care environment, The Queen’s Health System has announced the promotions of three long-term executives who will undertake new roles:

  • Jason Chang has been named the inaugural President of The Queen’s Health System Innovation Institute, which will be launched soon, and Executive Vice President of Innovation and Strategy for the health system.
  • George “Rick” Bruno, M.D., FACEP, has been appointed President of The Queen’s Medical Center in addition to his role as President of Queen’s University Medical Group.
  • Darlena Chadwick, MBA, MSN, FACHE, will serve as Executive Vice President and Chief Operating Officer of The Queen’s Health System.

“Focusing one of our key leaders on innovation will allow Queen’s to introduce new technology and create new models of care to significantly improve access and create a seamless experience for our patients,” said Jill Hoggard Green, PhD, RN, President and CEO of The Queen’s Health System.

Queen’s is experiencing rapid growth while embarking on a 10-year strategic plan to further improve access to high-quality care – where, when, and how consumers want to receive it. To advance its new strategic direction, Queen’s will not only transform its facilities and campuses, but will also continue its evolution to a clinically integrated health system.

“Collectively, these highly qualified and committed leaders have more than 75 years of clinical and management experience that will keep Queen’s on the leading edge of health care delivery,” said Dr. Hoggard Green.


Jason Chang has been tapped to lead strategy and innovation for the entirety of The Queen’s Health System. Drawing on his deep connections with communities and partners across the islands, Chang will accelerate Queen’s vision of creating a clinically integrated, affordable system of care dedicated to being a lifelong health care partner. He will also oversee the system’s ambitious, statewide master facilities plan to ensure Queen’s is well positioned for future innovations in its delivery of health and wellness where, when and how it is needed.

An accomplished healthcare executive, Chang has more than 15 years of executive leadership experience. He was recently named one of Hawaii Business magazine’s “20 for the Next 20” and was named a 2022 Business Leader of the Year by Pacific Business News. After leading Queen’s through the pandemic and preparing it for the expansion of The Queen’s Medical Center’s Manamana and West Oʻahu campuses as COO and EVP of the health system and President of The Queen’s Medical Center, Chang is ideally suited to drive the health system’s efforts in the critical areas of strategy and innovation.


George “Rick” Bruno, M.D., FACEP has been named President of The Queen’s Medical Center. Dr. Bruno currently serves as President of the Queen’s University Medical Group (QUMG) where he grew the Queen’s community of physicians by 150 percent in less than 18 months despite the many challenges presented by the pandemic. This tremendous achievement would not have been possible without the trusting relationships Dr. Bruno has built amongst physicians and clinical teams. In his expanded role as President of The Queen’s Medical Center, Dr. Bruno also will lead inpatient care, ensuring that every patient receives high quality, personalized care grounded in evidence and compassion.

Dr. Bruno joined The Queen’s Medical Center in 2015 and played a critical role in negotiations of Queen’s three-party Affiliation Agreement with The University of Hawai‘i John A. Burns School of Medicine and University Health Partners in 2021. This innovative partnership created QUMG, a group of more than 600 physicians and advanced practice providers that is dedicated to enhancing education and training for the next generation of healthcare professionals while improving care delivery models for all the residents of Hawaii.

Darlena Chadwick MBA, MSN, FACHE has been named Executive Vice President and Chief Operating Officer of The Queen’s Health System. She brings a wealth of experience to these roles, having built successful clinical programs in oncology, women’s health, neuroscience clinical program and other services. Chadwick’s initial focus will be on improving patient health by increasing access to care whether that care is delivered in a clinic, in the hospital, or at home. 

Chadwick joined The Queen’s Health System in 2005 and currently serves as Senior Vice President and Chief Operating Officer of The Queen’s Medical Center – West O‘ahu. During her tenure, she positively impacted patient outcomes and operating margins and led the development of programs that brought high-quality health care to one of Hawaii’s fastest-growing communities. “These leaders share a common passion for reaching the highest levels of reliability, quality and safety in care delivery,” said Dr. Hoggard Green. “Leveraging their strengths will accelerate Queen’s goal of being a lifetime partner to those we serve and ensure we continue to fulfill our mission of improving the health and well-being of Native Hawaiians and all the people of Hawaii.”
