I love playing bridge with Zach. Zach is very fast and aggressive, two important qualities for modern day competitive bridge.  Zach and I have both benefitted tremendously from the usbf junior program (as individuals and a partnership).  Michael Rosenberg has been an incredible mentor and has taught us so much.  Looking forward to making the most of my last couple of years in the junior program.

 Born and raised in the Boston suburb of Newton, I was brought up in a bridge playing family; my mom, seeing an ad for bridge lessons, took up the game in 1999, and soon taught my brother.

At first, I was turned off to the game, but by the time I was nine years old, bridge had really piqued my interest. And soon, with the help of my family and a few mentors, I started playing the game competitively; at the age of 12.

Since then I finished second in the U21 Championships in Taicang, China, won the U26 championships in Atlanta, Georgia, and finished 5-8 in the U26 Championship in 2014 in Istanbul.

Currently, I am a student at Tufts University.
