About Us
Mission Statement
It is our Mission to provide our customers with extraordinary value by combining excellent customer service with quality building product distribution. Whether it is one pack from our warehouse location, or rail quantities direct from our mill partners, we provide our customers with unique and consistent solutions to meet their specific needs. By helping our customers manage their inventories and maximize their bottom line, we will in turn build and sustain a business on which they can rely.
Company History
Middle Atlantic Wholesale Lumber, Inc was founded in 1977 by Jerry Kolker, former President of the company. The initial focus of Middle Atlantic was the sale of bulk Western lumber species to customers in Maryland, Pennsylvania, and Virginia.
Over the next decade we continued to focus on Cargo stock. Then, in response to changes in the construction industry and our customers’ needs, we expanded our product line to include Spruce, SYP, panel products, and specialty items. Following Jerry’s retirement in 1999 his daughter, Mary Lou Carlson became President of the company. Over the last decade dramatic changes have taken place in the distribution chain of lumber and building supplies. Middle Atlantic has responded to those changes by adding industrial and government accounts to the customer base, emphasizing excellence in customer service, and providing a range of products to meet our customers’ needs.
Our primary inventory location is on South Newkirk Street in the heart of Baltimore.
We maintain a strong inventory to enable prompt delivery from stock, and we can provide mill direct shipments. We feature long lengths and custom services such as split units and special packaging.
