From The President -

With the closing of R.J. Ruschell Company due to Gregg Ruschell's retirement in July of 2012, D&D Company, Inc was started to replace R.J. Ruschell Company. After years of working and learning from two great gentlemen Bob and Gregg Ruschell, I have changed hats from "Employee" to "President" with the same philosophy of providing maximum customer service and support as R.J. Ruschell Company.

I have been fortunate to represent a product as high in quality as Link Seals for the past four decades. I also enjoy providing Link Seals to local businesses in the Mid-Atlantic region.

I would like to thank Bob and Greg Ruschell for their service and dedication to the industry and I look forward to providing your business with that same level of service. The bar was set high!

D&D Company Inc. is family owned and operated. I work alongside my family Diane Young, Kenny and Christine Young and Laura and Matt Kimmel.

Thank you for visiting our web site and we look forward to working with you.
