A desert girl at heart, I grew up in Arizona surrounded by mountains which is where my love of hiking and outdoors started.

For residency, I attended SUNY Downstate for my general psychiatry training. I became involved with advocacy work through AACAP, attending the annual legislative conference where I presented an important bill which supports mental health access for BIPOC communities to Senator Schumer’s office. As I said I love the outdoors, and even did a month-long NOLS wilderness medicine backpacking trip in New Mexico as my last month of medical school.
