Sanjali Kumar, MD
Creighton University School of Medicine

Hi! My name is Sanjali, which is a confusing name, I know. It’s a combination of my parents’ names, which is the kind of dorky-sweet thing that happens when you’re the first kid to be born on both sides of your family. I grew up (with every substitute teacher mispronouncing my name) in Texas, and then Southern California, where I attended UCLA and graduated with an undergraduate degree in Psychobiology. After that, I completed my first two years of medical school at Creighton University’s home campus in Omaha, NE, and the second two years at Creighton’s satellite campus in Phoenix, AZ. And now, I am so excited to add BWH and the East Coast to my list of adventures! Throughout the span of cities and training facilities I have called home during my life, I have been drawn to working with underserved populations at free clinics, both locally and internationally. I hope to continue this momentum and build a holistic career in cultural psychiatry. In my free time, I love all kinds of dancing, theater, traveling, petting dogs, and exploring Netflix.


Arya Shah, MD
Mayo Medical School

Arya was born and raised in Los Angeles, California and attended the University of Southern California for her undergraduate degree in neuroscience. She surprisingly chose to make the trek east to Rochester, MN where she completed medical school at Mayo Clinic School of Medicine. Not feeling like she had moved east enough, she traded the tundra for the Atlantic Ocean when she moved to Boston to pursue a residency in psychiatry. She currently makes hot yoga, Pilates, painting, ice cream, and embroidery a part of her daily life as a resident. She has explored medical ethics and narrative writing during her residency and hopes to make them a part of her future psychiatry career, whatever and wherever that may be!


Erica Siwila-Sackman, MD
Tufts University School of Medicine

Erica majored in Economics, minored in Neuroscience, and worked in a memory disorders clinic while completing her undergraduate degree at Williams College.

In medical school, she was a member of AOA, served on multiple curriculum committees, taught medical interviewing to first year students, volunteered as a co-leader for a program that facilitates intergenerational relationships with seniors, and conducted home visits with seniors in the community.  She is interested in Geriatric Psychiatry. Erica enjoys cooking, hiking, running, and playing with her dogs.
