HAGÅTÑA (The Guam Daily Post) — The Guam Memorial Hospital Authority is bidding farewell to its acting administrator of medical services, Dr. Vincent Duenas, after 45 years of service as an internal medicine doctor.
Hospital leadership described Duenas as a “remarkable doctor” in a press release issued Thursday.
“GMHA is proud to have had the privilege of working with Dr. Vincent Duenas. He is an outstanding individual, a remarkable doctor, and both a blessing and an inspiration to the people of Guam. He is an extraordinary physician whose commitment to his island is immeasurable. GMHA will miss his positive spirit, his incredible work ethic and the outstanding care he has given to patients for over four decades,” the hospital authority said in the release.
Thanking him for his years of dedication to the people of Guam, the hospital authority said Duenas retires at the end of March.
“Dr. Duenas has served his people faithfully and professionally as a doctor in the private sector, the University of Guam and at Guam’s only public hospital, GMHA. In 2019, Dr. Duenas became the medical director at the GMHA Skilled Nursing Facility, where he oversaw the care of its residents who need long-term care,” the hospital authority said in the release.
Part of the GMHA team for over four decades, Duenas has served in a number of capacities, according to the release.
“Since he first graduated from medical school, he has held several upper-level positions, such as medical director of respiratory therapy and as employee health physician. He has also served in multiple executive roles over the years, including three times as GMHA’s associate hospital administrator of medical services. Until his official retirement this week, Dr. Duenas is currently the acting associate hospital administrator of medical services,” GMHA said in the release.
Duenas graduated with his medical degree in 1976 from the St. Louis School of Medicine before furthering his expertise, according to the release.
“He completed his internal medicine residency at Michigan State University Kalamazoo Center for Medical Studies in 1979 while simultaneously working as an internal medicine resident at Bronson & Borgess Hospital. That same year, Dr. Duenas became a certified diplomate with the American Board of Internal Medicine and a privileged doctor at the public hospital in his home island of Guam,” the release said.
Dr. Vincent Duenas, Guam Memorial Hospital Authority acting administrator of medical services, answers questions during the Guam Legislature’s oversight hearing on Monday, Feb. 26, 2024, at the Guam Congress Building in Hagåtña.
