Schneider was born on 15 October 1954, and is a native of Schifflange, Luxembourg. She first became involved in ice hockey in 1974 as a volunteer scorekeeper, and stayed in the game for over 40 years. She has served as the team president of Tornado Luxembourg since 2001. When her tenure as president began, the team played in the fourth German division. When rinks in the Rhineland region closed and the level of play declined, she looked for an alternate solution as opposed to traveling further into Germany for games. In 2005, she negotiated with the French Ice Hockey Federation to get permission for Tornado Luxembourg to play in the French Division 3. As part of the agreement, the team is eligible for promotion to the top Ligue Magnus tier, but is unable to become the French champion and represent France at international competitions for club teams. Schneider commented on the agreement by saying, "I think it's fair since we are already Luxembourg's champion by regularly beating our only competitor, the Beaufort club". Schneider has operated the Tornado as an amateur team which does not pay its players, and covers its costs by a sponsorship from Škoda Auto.
Schneider joined the IIHF council in 2008, as only the third female elected to the position. She served on the IIHF's competition and in-line hockey committee. Her duties included supervising the 2010 Winter OlympicsWomen's ice hockey tournament, and presiding over the 2011 IIHF Women's World Championship. At these events she enforced IIHF regulations, investigated complaints from participating teams, ensured proper advertising procedures, and oversaw the medal presentation and flag-raising ceremonies. She also helped revise and expand game regulations for the Ice Hockey World Championships. The IIHF honored Schneider with the Paul Loicq Award in 2015, for her contributions to international ice hockey. She formally received the award during the 2015 Men's World Ice Hockey Championships in Prague. As of 2019, she is the only person from Luxembourg to be so honored. She was surprised to be given the award, considering that she represented a nation in the third division of IIHF competition. She stated that, "You can't ask for more than receiving an award for something you're doing with love and passion. I hope I can still go on some more time because hockey is my life". In 2014 Schneider had announced plans to retire from hockey in 2016, stating that she was "proud to have seen hockey in Luxembourg go a long way". She later withdrew as a candidate from the elections for the 2016 IIHF council.
Personal life
Schneider worked as an executive secretary at ARBED, then worked in the family's mechanical workshop. She was introduced to hockey in the late 1960s by her husband, Nico Scheier, who was a goaltender for a team in Beaufort, Luxembourg. Their two sons began playing hockey at ages four and five, and the oldest son Ronny, served as team captain of the Tornado. Her sons and three of her nephews played on the Luxembourg national ice hockey team. Schneider's brother Alain has served as the president of the Luxembourg Hockey Federation.
