Our Team just wrapped up an amazing new store build in Ankeny, IA and it’s officially open for business!

What makes this project especially meaningful is that it was truly a team effort. Seneca’s General Contracting, Construction and Service teams all came together to coordinate and complete the installation. When our teams collaborate like this, we’re able to deliver projects efficiently, maintain quality and ultimately help our customers open their doors for business.

Meet Dan Boothroyd, the Equipment Sales Supervisor at Seneca!

Dan has been with Seneca for almost 28 years and loves Seneca's fair and family oriented culture. He also loves that there's always something new to learn so it's never boring!

Dan has always been an outdoorsman and loves hunting, fishing and camping. Spending time with grandkids demands a lot of his attention, but it's worth it to cherish all of the moments since they grow up so fast.

This year he plans to master the world of our ERP. Outside of work he hopes to spend time with family hunting and fishing like normal.
