Prior to the 1988–89 curling season, Schmirler and Jan Betker found themselves curling with different teammates, attempting to put together a stable squad. After a disappointing season, Schmirler decided to skip for the 1990–91 season, with Betker playing third. They recruited Joan Inglis (McCusker) to play second, and McCusker recommended Marcia Gudereit as a lead. This rink won the provincials in their first year together and finished in fourth place at the Scott Tournament of Hearts. In 1993, the Schmirler rink again won the provincial title to move on to the Tournament of Hearts. Her rink defeated Maureen Bonar in the finals, giving Saskatchewan its first national women's curling championship since Marj Mitchell's win in 1980. The rink moved on to the World Championship and defeated Janet Clews-Strayer from Germany in the final that year, winning Canada its sixth world women's title. The next season, she and her rink competed at the Tournament of Hearts as defending champions. The team finished first in the round robin, and defeated Connie Laliberte in the final to clinch a second consecutive Canadian championship. She and her team then represented Canada at the World Women's Curling Championship, where they finished first in the round robin. She then advanced to the playoffs, and won the semifinal against Josefine Einsle of Germany and the final against Christine Cannon of Scotland. With her win in the final, she and her team clinched their second world championships, equalling their run from the previous season. At the time, no other Canadian women's rink had won consecutive world championships. Schmirler returned to the Tournament of Hearts the next year as the defending champion. She and her team finished with an 8–3 win-loss record and advanced to the playoffs as the second seed. She lost her next two games, however, and failed to advance to the final, losing a chance to win a third consecutive title. The next season, Schmirler added Renelle Bryden to the lineup, as McCusker took the year off. For the 1996 Saskatchewan Tournament of Hearts, Gudereit who had been playing second was replaced for health reasons by Karen Daku. At the provincial Hearts, the team fell to Sherry Scheirich (now Middaugh) in the final.
