Always looking for opportunities to serve his people, Duenas joined the University of Guam that same year as its Student Health Center Physician where he kept the students current with their immunizations and other health requirements until 2003.

Dr. Duenas has been part of GMHA for 45 years, 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.

He has worked as the Associate Hospital Administrator of Clinical Services and Associate Hospital Administrator of Professional Support Services. 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 needed long-term care.
