Philosophy of Care

My personal philosophy of care is deeply rooted in the respect for each individual patient and in considering each patient's background as it applies to their medical history. In keeping an open-minded approach, I believe this allows patients to feel comfortable enough to be an active member of their own care.

I pride myself on the ability to perform a comprehensive analysis of all the information of each patient's unique situation and in doing so, formulate their best plan of care. I strive for transparent communication including discussing the reasons for an Infectious Disease referral, which can be a daunting, but overall important experience in the patient's comprehensive health care.

I believe that ultimately, the patient and physician, as a team, develop the best treatment strategy. I focus on delivering information in a way that makes sense and will be supportive as treatment options and possible outcomes are explored. At my core, I integrate humor, empathy, and smiles as I get to know patients on a personal level.
