Philosophy of Care
My goal is to provide the care and advice that I would want for myself or my family. I pride myself on considering all options for the treatment of any condition, not just those that are surgical.
I also pride myself on listening to patients and their families. Having any medical problem is difficult, navigating health care should not add to that problem. I also try always to be available for questions as oftentimes they arise between visits.
