Patient Reviews
Feb 02, 2024
Just before our planned two-month trip to Hawaii, I was told that I had a bile duct stone that would have to be removed and that could at any time cause serious problems. With no more information than that available to us, including what might be possible if we stayed, we left anyway and literally walked in to Dr. Ah Loy's office unannounced. His staff was friendly, diligent and helpful in working with us on the paperwork required for anything to be done. Once through that, I got a call from Dr. Ah Loy. The call was Friday afternoon. At 6:30 a.m. on Monday, I checked into the hospital and the procedure was done two hours later. I cannot sufficiently express my gratitude to Dr. Ah Loy and his staff for the competent, caring and compassionate treatment I received.
