Media Coverage

We’d like to thank a few of the associations we are a part of for covering our award winnings and special events in their media publications. A few of our most recent articles include the ESOP 2019 Company of the Year Award, the GAWDA media article honoring our 60-year anniversary, and the coverage of one of our employee’s children receiving the GAWDA 2020 Scholarship. Most recently, our CEO Ryan Diekow was interviewed by local Fox9 KMSP about the higher dry ice demand due to the rollout of the COVID-19 vaccine.
