The line between work and play is hard to define for Rob Schoenbach, who is both a head coach for Ice Hockey in Harlem and a public-school teacher at P.S. 28-M, located in central Harlem.
On weekdays, Schoenbach can be found in his science classroom teaching children in grades 3-5 everything from photosynthesis to the makeup of atoms. But on Monday nights throughout the winter, he can be found at Central Park's Lasker Rink, reviewing everything from hockey posture to the offside rule.
