Thinh Ho MD

Board Certified Family Medicine

Dr. Thinh Ho was born in an educated family. He initially entered the medical field to follow his father’s wish. In Vietnam, doctors were always scarce and there were too many ill people.  Due to this, his goal was to help humanity and lessen their pain. Soon, his love for medicine blossomed and so did his passion for saving lives. He completed his training in general medicine in 1992 in Saigon, Vietnam. He received a degree in Pediatrics at the Royal Children’s Hospital and Melbourne University in Australia by 2000. In 2004, Dr. Ho immigrated to the United States to be united with his family, after practicing for more than 10 years at ISOS International Clinic and Children’s Hospital No. 1 in Saigon, Vietnam.

He completed residency in Family Medicine at Yeshiva University and Montefiore Medical Center in North Bronx, New York in 2009. After residency, he practiced in Tacoma, Washington where he also ran his own family medicine clinic. This was his way of helping out the Vietnamese community. In July 2016, he moved to Honolulu to be close to his big family. He enjoys family time the most, especially with his wife and two children.

Dr. Ho loves his new home. He enjoys working on his garden with his wife. In the end, he wishes to continue serving humanity and ease suffering worldwide.
