Born in the Big Apple, Marty learned to play bridge at the age of eight by observing his parents and uncle. His biggest bridge thrill was either winning the 2017 Bermuda Bowl, the 2010 Team Trials, the 2011 Vanderbilt, the 2013 Platinum Pairs or the 2016 Spingold. However, he considers his "greatest achievement" a toss up between his marriage to his wife of twenty-eight years and getting to the finals of the Grand Nationals in 1976 (at age 17 still the youngest player to reach a National Championship final). But there was a famine of over twenty-eight years until he won the Swiss Teams at the 2004 Fall Nationals. It is interesting to note it may have been the longest stretch between 1st and 2nd for anyone. Indeed, it took Marty's teammates in the National Swiss (Gavin Wolpert and Vince Demuy) only one National to transcend from bridesmaid to bride! Marty enjoys few leisure moments for hobbies other than bridge as his professional commitments as a manager of life insurance investments and attorney are very time-consuming.
