Dr. Supannee “Jill” Rassameehiran

(Thursday, January 9, 2024; Dededo, Guam) — Guam Regional Medical City (GRMC) is excited to announce the addition of Dr. Supannee Rassameehiran, a board-certified gastroenterologist, hepatologist and liver transplant specialist. Dr. Rassameehiran is a specialist in treating patients with conditions that affect the stomach, intestines, liver, and pancreas. She pursued a postdoctoral fellowship in hepatology, focusing on liver diseases, liver transplantation, and liver cancer care. Dr. Rassameehiran is one of only two gastroenterologists currently practicing on the island, with the unique ability to treat liver diseases and cancers, an area of critical need for the local community.

Dr. Rassameehiran’s expertise spans a wide range of gastrointestinal (GI) disorders, from common issues like acid reflux and irritable bowl syndrome (IBS) to more complex conditions such as chronic liver disease, cirrhosis, and liver cancer. Dr.

Rassameehiran is a key provider in treating chronic liver conditions that require advanced, specialized care. This expertise includes providing liver disease screenings (such as hepatitis B and C assessments), chronic hepatitis, and cirrhosis.

Her arrival at GRMC is a game-changer for the local community. “Dr. Rassameehiran’s arrival at GRMC is a significant step forward for both the hospital and the island as a whole,” said Dr. Edison Manaloto, GRMC Chief Medical Officer. “Her expertise in hepatology and liver transplantation fills a crucial gap in Guam’s local healthcare, especially in the treatment of liver diseases and liver cancers. With her specialized skills, patients on Guam no longer need to seek life-saving treatments off island. This not only improves access to high-quality healthcare, but also reduces the emotional and financial burdens that come with seeking treatment elsewhere. Her ability to offer comprehensive care for both digestive and liver conditions ensures that GRMC can provide a

holistic approach to gastrointestinal health, ultimately improving outcomes and enhancing the overall health of the community,” Manaloto added.

Dr. Rassameehiran completed advanced training at top institutions, including Baylor College of Medicine in Houston, Texas, and the Medical College of Georgia at Augusta University. She also earned her medical degree in Thailand and practiced on the U.S. mainland, where she worked at MultiCare Yakima Memorial Hospital in Washington.

“I am honored to be part of the GRMC team and to have the opportunity to provide care to the people of Guam. Liver diseases and cancers are often complex, but with the right care and treatment plan, we can make a significant difference in a patient’s quality of life. My goal is to bring that level of expertise to the community, offering comprehensive treatment options from liver disease screenings to liver transplants, and to provide personalized care for each patient,” said Dr. Rassameehiran.
