I have had the opportunity to cross paths with AJ Foss many times over the past 10 years, and I have been consistently impressed with the quality of this organization. The number of contractors that trust AJ Foss for their precast concrete needs tells the story. Contractors don't want to insecurity, and the trust they put in AJ Foss speaks volumns. A quality family-run operation that has served southern NH for decades. If you are a contractor and you are NOT using AJ Foss, you owe it to yourself to check them out.

About the Author:

My father started the Andrew J. Foss, Inc. precast concrete company in 1963 at the age of 19. My precast education started at a very young age. He taught me everything I know about creating quality precast concrete products, from septic tanks to concrete headwalls. He also taught me to succeed in business you need to offer an exceptional product and treat your customers as you would expect to be treated. Now, as an owner of the company along with my brother Matthew, we've taken everything we've learned from our father to start the next generation of our family-owned precast concrete company.
