Zablocki VA Medical Center

My philosophy of patient care is patient centered care. I evaluate a patient by taking into account the person as a whole person with biological, psychological and social needs rather than a cluster of diseases or abnormal findings. I educate my patients to understand their illness, listen to their concerns, share them with my thoughts and involve them in the decision making of their care.
