Philosophy of care | I believe evaluating and treating each patient as a whole rather than a sum of individual parts is paramount to understanding and treating disease. | Why I entered medicine | A medical career allows me to contribute my knowledge and time to improve people’s lives. | Community involvement | I mentor students in the sciences and engineering. I also take part in public health projects and endeavors dealing with wellness. | Personal interests | I enjoy music, technology and outdoor activities.
