Proactive & Preventive RecommendationsI have been seeing Dr. Tachibana for more than a decade. During these years, he has been very proactive and prescribed preventive procedures which helped me identify the dangers before hand and take appropriate actions. There are a couple of instances in last 5 years (one very recently) which helped me avoid a heart attack with timely intervention. I really appreciate his due diligence and the way he approaches treating the patients.
