Thien M. Do, MD, FACC

"These fellow human beings were in desperate conditions and they reached out for help. 

I just could not turn my back on them.”


Dr. Thien Do’s interest in humanitarian medical relief began in 1996 while serving as a team physician on a humanitarian dental mission to a refugee camp in the Philippines.  Although Dr. Do’s intended role on that trip was to care for the team of volunteer dentists, when the residents of the refugee camp learned of the doctor’s presence in the camp, they lined up in front of his cabin hoping that he would help them, too. 

“I did all that I could for the people that I met on that first trip,” recalls Dr. Do, “but I realized how much more I could do with real resources and manpower.  That idea never left me. These fellow human beings were in desperate conditions and they reached out for help.  I just could not turn my back on them.”


After leaving Vietnam in 1975, Dr. Do and his family came to the United States as refugees.  He became a U.S. citizen in the 1980s.


In his role as Director of World Health Ambassador, he has led medical and dental missions to Cambodia, India, Laos, Myanmar, St. Vincent and Vietnam, and has built a strong foundation for the organization, which now includes volunteer members from across the U.S. and overseas.

In addition to his work with WHA, Dr. Do is the director of a multi-specialty medical facility located in Northern Virginia where he serves as the lead staff Cardiologist.  The medical group consists of cardiology, pulmonology, radiology, urgent care, and family medicine services.  Dr. Do has practiced medicine for more than 20 years.      

Dr. Do has also served as Assistant Clinical Professor at  the Georgetown School of Medicine and Uniformed

Services University of the Health Sciences. 

While serving in the U.S. Army with the rank of Major, Dr. Do held multiple leadership roles at the Malcolm Grow Medical Center, including Director of the Coronary Care Unit, Intermediate Care Unit and Pacemaker Implantation Services, and Director of Non-invasive Labs. 


Dr. Do has also served as Vice-President of the Northern Virginia Vietnamese Medical Society and as Vice-President of the National Vietnamese American Medical Association. 

Dr. Do received his Medical Doctorate from the George Washington University School of Medicine and holds a Bachelor of Science in Chemistry from the University of California at Berkeley. He completed his residency at the William Beaumont Army Medical Center and his cardiology fellowship at the Brooke Army Medical Center.
