The best care is on your side

Innovative Equipment

Many digestive system conditions and diseases have similar symptoms but different causes. These conditions can be complicated and challenging to diagnose, that is why we use state-of-the-art imaging and technology - including Hawaii’s first and only portable FibroScan(R) Mini+ 430 device.

Focused Care

As a Gastroenterology and Internal Medicine board certified physician, we specialize in the prevention, diagnosis and treatment of diseases of the digestive system.

Personal Treatment

We believe personal treatment leads to exceptional care so we take pride in the individual experiences our patients receive. Compassionate, specialized care is a cornerstone of what we do.

Surgical Expertise

With wide experience and in-depth knowledge from working in the Gastroentology field for years, Dr. Ona is trained in the latest surgical techniques should surgery be a necessary treatment or selected option.
