The German international has been a key part of the Terriers first-team since he arrived in a club record £1.8 million deal from 1860 Munich during the summer of 2016.
It was also the 28-year-olds penalty which sealed the clubs return to top-flight football for the first time in 45-years.
"It's nice to win the awards because it shows all the hard work you put in all year has paid off," remarked Schindler.
"But everyone is putting in so much effort and what we are all working for is to stay where we are at the minute – in the Premier League.
"That's what I am working towards and what my family have sacrificed a lot for.
"The penalty at Wembley was a life changer for me and I want to stay where we are now with this football club.
"I am 100% focused on what we have to do because if you aren't you are going to be punished in this league."
