To Our Valued Customers,

The Governor of Pennsylvania through his Emergency Declaration has ordered all non-life sustaining businesses in the Commonwealth to be closed. Therefore, we will be closed for business indefinitely until further notice. We have made this difficult decision to close our facility to protect our employees and customers in compliance with the Governor's order.

This is obviously a fluid situation that we will be monitoring, so we will adjust our plans accordingly. We will continue to keep you up-to-date as we make our way through this difficult and unprecedented emergency. If you need assistance, please contact Mike, Rick, Bill, or Andy directly. Thank you and stay safe!
