Philosophy of Care

I strive for a patient and family centered approach to cardiac care, through close collaboration with colleagues in other specialties, such as oncology, other divisions within cardiology and within the cardiomyopathy and non-invasive imaging groups. Long-term management of cardiomyopathies requires a team of care providers.  Supporting all members of the team is a core philosophy, through continuous education and investment in regular interpersonal conferences.
