Lomax is a local Colorado window and door company with its main office in Fort Collins.

Donovan and Dawn Isaacs are the proud owners of Lomax Window & Door Co. Donovan started building windows in the early 90's in Saint Cloud, MN. Being from the Midwest has given Donovan a strong work ethic and the ability to build like none other (it's too cold to do it a second time, so get it done right the first time around)! He moved to Colorado in 1999. Through the years, he has moved up the window ladder, and his knowledge of the industry is incredible! The opportunity to own and operate Lomax was too good to pass up! With Dawn on board to run the office, they figured it would be a great family opportunity.

Donovan and Dawn are local Fort Collins residents. They live near Horsetooth Reservoir with their three sons and many, many, fuzzy and feathered friends. The Lomax Window and Door Co. team is comprised of family and employees who are known and trusted to get the job done!

We want our customers to be part of our team as well and to help us continue to grow as a quality Colorado company!
