Hello Everyone! I am proud to say that I'm from the area. Springfield/Baystate are home. It all started with a shadow experience in high school that tied me to Baystate. From that movement I knew that I wanted to train and work here. I attended medical school at University of New England College of Osteopathic Medicine and from there I was able to return to Western Massachusetts where I've been lucky enough to serve the community responsible for my achievements.
My friends say the correct answer to 99% of the questions about me is ‘food’. I enjoy trying different cuisines and exploring new restaurants. I'm also a huge HGTV fan, and you can often guess that my weekends off revolve around some type of home improvement project.
I can’t wait to start the next chapter of my life with the Baystate GI family and look forward to continuing my career here at Baystate!
