Dr. Kaneshiro is truly special. Spending a considerable amount of his intellect and experience to be very thorough and careful with planning the next steps in treating a challenging health condition. He is able to look at the issue from all angles and what the implications are with pro and con analysis. Dr. Kaneshiro cares and I value his opinion.

Dr. Kaneshiro as extremely thorough and gave me more answers than I’ve had from my previous doctor in over a year and a half. We have a plan in place to determine the root cause of my stomach issues, which I didn’t have before.
