Sergey was passionate about life, always smiling and cared deeply for his family, friends and colleagues. He treated everyone like family and would always lend a hand to those in need. He was a leader to many and a teacher to all. His honesty guided him and his heart made him a fun person to always be around. I will truly miss you my friend. And although I would purposely let you beat me at table tennis, I will never forget some of the lessons you taught me, not just in ping pong but also in life. Craig
