Alex and Ethel Despenas were the founders of Midwest Construction. Alex was one of four children born to immigrant parents from Greece. His parents came to America to live the American Dream. Alex's father worked for a local cement plant in Mason City, Iowa. He ensured his children were given an education, and he saved money for their future.

Alex watched his father work very hard providing for their family. His father taught him and his siblings that they could be successful in whatever they chose to do, learning the in's and out's of any job, and to be the best worker possible.

During high school, Alex and his brothers worked at the local cement plant loading bags of cement into box cars, this helped contribute to their family. When WW2 began, Alex like many others left high school and joined the military. Alex was enrolled into the Navy. Alex was a Naval Air Gunner; he was shot down twice, earning two purple hearts.

After the war Alex came back to Mason City Iowa, found a job working for a clothing store. During this time he met his future wife Ethel and they married. Soon after, Alex was offered another job, a jewelry store sales position. He had very good rapport with customers. A man who routinely purchased jewelry from Alex asked him if he would come work for him, selling siding. After years in the sales industry, Alex decided to move on and explore the siding industry. That began the journey into the Home Improvement Industry.

Alex learned everything he could about the siding industry. He also realized there was a lot of room for growth. He decided that the Home Improvement Industry needed to be changed. Alex believed customer's experience, from start to finish needed to be top priority. His vision of offering better products and service would be what the Home Improvement Industry needed. Scouting the top manufactures in order to offer the best products and finding qualified installers to complete his projects was a major goal of Alex's.  In 1957, Alex and his wife Ethel took the biggest risk of their lives, with the money they had saved and a vision; they opened Midwest Construction & Supply.

Alex believed if he could control the sales process all the way to the installation, he could create customer satisfaction. Communication with customers was another huge component of his vision. He wanted to make sure his customers would have a pleasant experience. If his customer had great service and product then they would want to tell others, which would lead to new customers. Alex and Ethel passed down their strong work ethic, family comes first values, and his vision for their company to their six children. To this day, their children continue to follow Alex and Ethel's vision for the family owned and operated company, Midwest Construction.

In 1958 Midwest Construction's slogan was created; “Quality Products & Quality Installation." We stay true to those values!
