Philosophy of care | I always try to find a balance in providing cost effective care, while looking out for the individual. | Why I entered medicine | I always enjoyed the challenge of taking care of patients, particularly the balance of science with the humanistic side of care. | Community involvement | I am involved in community service through a variety of organizations | Personal interests | Sports, particularly hockey, running, weight training and skiing, while I am not chasing after or driving around my 5 children.
