The company said Andrew Bernosky has been hired as technical sales manager and John Doan has been promoted to regional technical manager for the west and midwest regions.

“The addition of Andrew and promotion of John allow for a much-needed expansion to our technical team,” stated Karnak COO Chris Salazar. “These roles will help support the rapid growth we’ve been experiencing in all of our markets and in the west in particular.”

As technical sales manager for Karnak, Bernosky will monitor and maintain product code compliance, become the point of contact for code and government regulations, assist in prioritizing research and development projects, oversee handling of warranted roofs and maintain all technical documents.

Doan previously served as a regional field manager in north Texas before being promoted to the regional technical manager. In this role, he will become the technical point of contact for all business functions in the assigned region. 

Prior to joining Karnak in 2015, Doan worked for Trufast Corp. where he spent six years as southwest regional manager.  He holds a bachelor’s of science in construction engineering technology from Montana State University.
