"Although I am a surgeon, I too have been a patient and had family members with serious medical problems requiring intensive medical treatments and operations. By combining the experiences I have gained through my training and practice with the experiences I have had as a patient and family member of a patient, I hope to provide a unique perspective that will help build a trusting relationship with every patient and family. I believe this trust is the foundation for a strong doctor-patient relationship and the key to providing the best medical care."
