Our Residents

Shivalika Mehan, MD
PGY-3 Chief

I was born in India, raised in New York, and attended St. George’s University School of Medicine in Grenada. For the last decade, I have been living in New Jersey and knew I wanted to stay close to home when it came to residency. Overlook Hospital was my top choice, and it was not a hard one to make- it had everything I was looking for and more. What I cherish the most is the relationship I have built with my co-residents and attendings. When I was offered the opportunity to serve as a PGY3 administrative chief, I knew this was my way to contribute to the program. My focus currently is on continuing to make the academic portion of the curriculum an enjoyable and enriching one. I plan on pursuing a career as a hospitalist. Outside of work, I enjoy spending time with family and friends, and playing sports (volleyball, badminton, & swimming).

Sheryl Htoo, MD
PGY-3 Chief

I was born in Yangon, Myanmar and later immigrated with my family to Vancouver, BC, Canada. Inspired by my mother and grandmother who were OBGYNs, I decided to pursue medicine and obtained my medical degree from St. George’s School of Medicine, Grenada. At OMC, I found a program that promotes diversity and inclusivity in addition to providing a robust training experience. The friendly work environment, diverse patient population, and close support/mentorship from the faculty were few of the many reasons that made Overlook my top choice in residency! As a PGY3 Chief, I advocate for our residents’ wellness and education while promoting a positive and fun working environment. I hope to ultimately pursue Endocrinology fellowship for the next chapter of my training. When I am not at work, I absolutely enjoy being outdoors - hiking and chasing sunsets. I also love to travel, cook, and play tennis in my free time.

Tatiana Echeverry, MD
PGY-3 Chief

I was born in Columbia and grew up in Queens, NY. I pursued medical school at St. George’s School of Medicine, after completing a Master’s in Biochemistry and Biophysics. I was drawn to Overlook because of the strong culture of mentorship and support from faculty. Here at Overlook, I have had the support to expand my scholarly portfolio by presenting abstracts at major national cardiology meetings and publishing several manuscripts. I am working to expand our research and evidenced medicine curriculum as a research PGY 3 Research Chief. I also instituted the peer mentorship program here at Overlook and excited to see its growth. I plan on pursuing a fellowship in Cardiology with emphasis on providing care to our underserved communities. Outside of work, I enjoy long nature walks, powerlifting and exploring new restaurants in the area.
