A New Chapter
Alberta Wilbert Sales Ltd. (“AWS”) is proud to announce that it has embarked on an important ownership and leadership transition. Effective December 6, 2024, AWS was purchased by Petwin Bancorp Inc. (“Petwin”), a family-owned investment firm based in Calgary. Petwin is pleased to be honoring the contributions of outgoing owner Leonard Traub while looking to the future under the leadership of newly appointed President, David Dallaire. David’s appointment as President is effective March 10, 2025.
“On behalf of the Board of Directors, I want to extend our deepest gratitude to Leonard for building the foundation of the company and entrusting Petwin as the new owner of AWS,” said Mike Devonshire, Chair of the Board of AWS.
David Dallaire, who currently serves as Sales Manager of AWS, brings extensive experience in the water and wastewater industries. Prior to joining AWS over 15 years ago, he worked for a large septic contractor in the Edmonton area. In both roles, David has focused on driving strategic growth and fostering meaningful relationships through partnership and collaboration. He is recognized as a technical leader within the industry and an excellent resource for AWS customers and staff.
“I’m incredibly excited about this next chapter for AWS,” said Dallaire. “AWS’ commitment to finding high-quality solutions for customers and providing timely and efficient service is something I’m very proud of. Alongside our senior leadership team and with the support of Petwin, I am incredibly excited to work with the AWS team, its customers, and its suppliers to continue this tradition.”
As AWS embarks on these exciting transitions, it remains committed to meeting the needs of its customers, suppliers, and employees.
“We are at an exciting juncture,” added Devonshire. “With David’s leadership and a strong foundation in place, we are confident in AWS’ ability to build on its past success while continuing to expand its product lines, service offerings, and geographic service areas.”
Under Leonard’s leadership over the past 50-plus years, AWS has grown from humble roots to become the largest supplier in Western Canada of prefabricated concrete products for the water, wastewater, and funeral industries.
