Our History

For over thirty years Allied Ventilation has been at the forefront of quality fabrication and installation in the plan and specifications and design-build markets for a variety of industries.   As the first female owned sheet metal fabricator in Michigan Mary and Nick Seraphinoff created a company that was ready to meet their customer's customized duct needs.


In July of 1981 Mary and Nick Seraphinoff formed Allied Ventilation in their house in the Detroit area.  Since that modest beginning they have transformed their shop into a multi-million dollar company specializing in custom ductwork.

Mary came from upper-management within a well-known furniture company in Michigan and Nick's background was well rooted in the sheet metal industry having been a detailer, estimator and project manager.  Together their business and duct skills have made Allied Ventilation one of the premier custom sheet metal design shops in the Midwest.

Mary and Nick have been very active in SMACNA  chairing many committees including Mary holding the office of President for their local chapter.  Nick sat on the National Industrial Contractors Steering Committee for five years and was also on the SMACNA National Board of Directors.

Along with the Sheet metal Workers International Association - Local 80 Allied has been in the forefront of a constant campaign of "working together" to ensure that both management and employees are moving toward the same goals.
