Expectations are high for events at the Milwaukee Art Museum. The culinary team at the Milwaukee Art Museum relies on Alto-Shaam ovens to provide the best banqueting experience.
While Copper Branch started the business relying on Alto-Shaam products, it was the start-up process and customer service that sold them on Alto-Shaam combi ovens. Rio Infantino was considering purchasing combi ovens from several vendors, but the support the company received from Alto-Shaam made the decision for him.
“Upon testing our products, we were able to get better service with Alto-Shaam. That helped us a lot,” said Andrew Infantino. “The customer service and ability to test the ovens made us choose and stick with Alto-Shaam.”
The ACTS community-based living facility has been using Alto-Shaam's products since 2000 to provide high quality food for their more than 8,000 residents. The Alto-Shaam Combitherm® ovens and hot wells allow ACTS to provide a large variety of meal options, faster cooking times and longer holding times.
