Interest in Palliative Care: I became interested in Palliative Care because I have experienced firsthand the struggle of a family member suffering from a serious illness. Palliative care was never offered to us and we had to navigate next steps alone. It was a very difficult process and I wish we had experts helping us with next steps and educating us with the disease process. The second reason I have an interest in Palliative Care is that I have always found it rewarding to be able to help patients with serious illnesses develop goals of care and lead these difficult conversations. I see Palliative Care as a road map for someone with a serious illness. This roadmap would provide family with tools, support and education to increase quality of life and decrease stress on the family.

Hobbies: Traveling, cooking and spending time with my family.
