Tucker, GA - Gypsum Management and Supply, Inc. (GMS), a leading distributor of drywall in the U.S., has made a strategic entrance into California and Hawaii markets by acquiring San Diego based J&B Materials, Inc. and its affiliated Hawaiian operation, Pono Building Materials, LLC.

“We are pleased to bring J&B Materials and Pono Building Materials into the GMS family,” says Mike Callahan, president of GMS. “Their commitment to delivering exceptional service, knowledgeable personnel, and an expansive product suite with a focus on safety fits well within our culture. This partnership provides us with an excellent opportunity to expand our service area into California and Hawaii while enhancing our West Coast coverage."

With locations in El Cajon, Escondido, Riverside, and El Centro, California, and one in Honolulu, Hawaii, J&B offers a wide variety of building products including drywall, stucco, lath and plaster, and fasteners, among others.

J&B Materials also provides timely delivery and stocking, but it’s much more than that for them. “We go above and beyond customer expectations and strive to get the job done right the first time,” said J&B president, Bob Young. “We have a quality, trained staff to provide the best possible services and products. Partnering with GMS, one of the most outstanding and respected distributors in this industry, is going to serve us and our customers very well.”
