Bill WelwoodVice President / General Manager

Bill Welwood is a native of Dallas, Texas and grew up in the world of home builders. Bill’s father was a builder in the Dallas area in the 1960’s and his mother was an interior designer, so he also acquired a strong background in design and architectural correctness. Bill and and his wife Liz have two children Travis and Kimberly.

As a home builder himself, Bill used to order cast stone products for his projects from American Masonry Supply, Inc., so he was familiar with their quality first hand. He worked for a large sized home builder in the area that helped him develop his skills as a project manager of large scale and simultaneous projects.

Bill came onboard with American Masonry Supply, Inc. in 2003.

"It helps to have that kind of experience as a builder and a manager – you already know their needs and have an idea of what’s going on in their thought processes. You understand the urgency involved."

From his youth, Bill has loved architecture and the building process. As General Manager for American Masonry Supply, Bill oversees all aspects of operations. His commitment to excellence reflects in the unwavering precision of the end product American Masonry Supply's customers demand.

Bill loves being outside and has a heart for mission work. He has been on trips to Guatemala and Brazil, and works locally in a prison ministry called Behind The Walls.

Jesse MendozaAutoCAD Expert

Jesse Mendoza studied architecture at the University of Texas at Arlington, where he became proficient in Auto CAD. Jesse has been a part of the American Masonry Supply, Inc team since 2001. He was attracted to this job because it gives him the opportunity to design, and it included being creatively involved in bringing a project to a higher place, including providing balance between the technical needs and the aesthetics.

AMS gets project designs from architects or homebuilders that are very basic. Jesse uses his knowledge of architecture to help ensure that the project is well proportioned and we take basic designs one step further and embellish them while keeping to the standards of the original design, intents, and constraints. Frequently clients want something more ornate than initially provided by an architect. Jesse helps ensure that the overall final design is harmonious and balanced, assuring that the proportions and embellishments are architecturally correct.

"I love being a part of the design process. The creativity process and love for architecture is a passion of mine."

Jesse's work involves assisting the sales team in providing design consultations, both in-house and in the field. He enjoys working with clients that know what they want and where they want the project to go and assisting in mapping out the project specifications.

Jesse hopes to be able to travel the world, visiting Europe and it’s old architectural sites.

Jesse values his fellow employees at AMS, their integrity and camaraderie. He also value the diverse set of projects that come through the door, many of which are custom projects that are technically difficult – these projects constantly challenge him to grow and to up his game.
