About Us

Behind the Keystone Culture

Established in 2009, Keystone Synergy offers a dynamic array of design and fabrication services across a variety of industries. Centrally located in North Texas, the Keystone companies are well poised to bring quality craftsmanship and exceptional customer service to their business partners both locally and across the country.


Larry Crist Sr. & A. Craig Ray Founders

Although they had worked together previously, Larry Crist and Craig Ray didn’t partner until 2011.  Keystone kicked off in January of that year with an ambitious business plan to build and sell 40 SandKings, eventually increasing the plan to 60 before the first one was even out the door. By the end of the year, 83 SandKings had been built and the company was operating debt-free. It was a storybook beginning with absolute perfect timing in the marketplace.

In 2012, Keystone introduced a Structural Steel & Erection division to offset some of the ebb and flows of the Oilfield Fabrication component of the business. Additional diversification and advancement has occurred in the years since, but their combined experience of 78+ years has allowed for continued growth with limited/no debt in an incredibly stable work environment.

On a personal basis as well as in their professional endeavors, faith is not only what brings them contentment, but it also drives them to make a difference in their industry. Larry and Craig believe God comes first, family second, and then everything else follows! They thrive on the fact that Keystone Synergy stands out among the competition because their goal is to truly honor God in all they do.

"The two phrases that I dread most are “back-ordered” or “long lead-time”…..those are like nails on a chalk board to me but I can honestly say Keystone NEVER tells me that. I get my quote requests back in a timely manner and I get the parts very soon after they receive my purchase order. I most recently had an incident where they processed my order and then ... personally took my control boxes to Fed Ex because I had missed the UPS cut-off time, they really helped us out of a jam!!!"

Alan Evans - Stingray Pressure Pumping (Customer)

"We appreciate the great working relationship we have. Keystone is a very professional, and well respected company. We have worked with Keystone since the beginning days of the company. I am very impressed, and proud to be a vendor for Keystone. The willingness to display and promote their Christian values is very much appreciated from our prospective. We hope to continue a long lasting working relationship with your company well into the future."

“Not only were they willing but a big help. They picked the units up, made the repairs that needed to be made and at a great price. My hats off to all the ladies and gentlemen at Keystone. Great company and Great Staff. Thanks Keystone”

Matthew Yates - Keane Group (Customer)

“Keystone is a best in class company that prides itself on their people and ensuring every job is done with integrity and true craftsmanship. As an industrial distributor we have witnessed first-hand Keystone’s true passion to have the best tools and products for every project. Keystone has diversified their portfolio beyond the Oilfield and expanded into Steel, Parts & Supply, and Ironworks and I’m excited to see them thrive for years to come!”

Erin Thompson - Grainger Industrial Supply (Supplier)

“WestAir has had the privilege of serving Keystone as their industrial supplier for almost 5 years. We have certainly had nothing but the best experiences with all of the employees and ownership. They hold true to their principals and are honest with their dealings with their fellow man. Their ability to diversify the work they do in their shop certainly is an exception compared to other manufacturers. This success is a strong display of the versatile skill sets this team has established. Thank you for letting us be a part of your success.”

Michael Crambes - WestAir (Supplier)

Higginbotham has had the pleasure of working with Keystone on their insurance and risk management needs. I’ve personally worked with the company owners since 2003, prior to the startup of Keystone. Keystone is a top notch professional company and I am honored to do business with such a fine company. They have demonstrated versatility with their ability to diversify to meet their customer needs. The employees seem very happy to be a part of this organization and that speaks volumes about a company. Keystone is a top notch company and we look forward to a very long business relationship and friendship.

But Thanks Be to God! He gives us the victory through our lord Jesus Christ.

Therefore, my dear brothers and sisters, stand firm. Let nothing move you. Always give yourselves fully to the work of the Lord, because you know that your labor in the Lord is not in vain.
