Philosophy of Care

My goal as a colorectal surgeon is to provide patient-centered-care. I want to make sure my patient's concerns are addressed by creating a treatment plan that works for them, they can understand, and follows the standard of care. I believe in treating every patient with dignity and respect as they navigate the journey of undergoing surgery. I will do my best to advocate for my patients to provide the best care possible.
