Company History

C&O Window and Door Company - Since 1956

​

C&O Window and Door Co. (C&O) was founded in 1956 by Angelo Coffee and Aldridge (Rose) O’Quin, in Pueblo, Colorado with the intent to manufacture and install aluminum storm windows. Aldridge acquired Angelo’s share of the business in 1963, however, the business name of C&O remained.

​

Aldridge and Rose were the principal owners and continued the manufacturing and installation of aluminum storm and sliding windows until Aldridge passed in 1977. Aldridge and Rose’s youngest son, Dennis O'Quin, had been working in the business since the age of sixteen and was pursuing his degrees at the University of Southern Colorado at the time of Aldridge’s death. Dennis and his mother, Rose, decided to continue the business with the vision of expanding product lines and offerings in 1978. Rose continued working in the business until she retired in 2006 at the age of 88.

​

Dennis purchased the business from Rose in 1983 and continued to grow and expand the business throughout Southern Colorado for both residential and commercial product and service offerings. Dennis has over 50 years of industry experience and his resume of glazing projects, both large and small, is extensive and can be found in every part of Pueblo and throughout Southern Colorado. Although Dennis has retired, he continues to lend his knowledge and expertise to the C&O staff and the construction community as needed. 

​

Dennis’ youngest son, Nick O'Quin, purchased the business in 2021 and continues the family legacy into the third generation of ownership. Nick grew up around the business and has been working with the C&O team full-time since 2010. Nick graduated from CSU-Pueblo with a B.S. in Business Management and has over 15 years of construction related experience. Nick has a vision to build upon the remarkable work of Aldridge and Dennis while continuing to serve the Pueblo community.
