Jeremiah Rivers started his career in the countertop fabrication industry when he was 16 years old. At the young age of 23, he founded River’s Edge Countertops in Oklahoma City, OK, and he has been evolving the business since its beginning in 2008. Last year, Rivers made the decision to consolidate machinery and reduce the number of shop employees — but he needed to ensure that the quality of the company’s work would not be jeopardized. A visit to Coverings in Orlando, FL, that year introduced Rivers to Joe Alva and the Poseidon Industries team who assisted him with all his shop’s needs. Rivers took some time to talk with Stone World about his growing pains, where he is today and how River’s Edge Countertops achieved success.  

SW: Tell us a little about yourself and how River’s Edge Countertops came about?

JR: My name is Jeremiah Rivers, and I started River's Edge Countertops back in 2008. I worked for another countertop company prior to that, starting at the age of 16. River's Edge was formed when I was 23 years old and has now been around for 18 years. We started doing only laminate countertops and then eventually grew into solid surface. We used to make our own recycled glass and concrete countertops. I eventually moved into natural stones, became a fully digital shop and grew rapidly over the years. In 2026, we got our new T-Rex dual-table installed, and we are very excited about it and love the machine. We used to have two sawjets and two CNC routers and condensed into one machine.

SW: What type of work do you primarily do?

JR: We have a background in a lot of builder work. We have done Box stores, Home Depot and Lowe's, but in the last couple of years, we have gotten out of all that. We now primarily do custom home builders, direct-to-consumer retail and work closely with designers.

SW: What machinery do you currently have in your shop?

JR: I currently have a Poseidon T-Rex dual table, a Bovone 4045 Stonedge polishing machine and an Iris scanner — the new 21K.

SW: Before investing in equipment, what were some points of consideration?

JR: The biggest point of consideration was maximum efficiency. We downsized the team, and I wanted to make sure we could produce more footage than before with a smaller team. The T-Rex Hybrid Cycle has allowed us to achieve that. Also, not having to deal with a waterjet has been a game changer. We cut faster and no longer deal with waterjet lines, garnet, waterjet tanks and the maintenance that comes with them.

SW: When/where did you first learn about Poseidon?

JR: I learned about Poseidon at Coverings in 2025. I met Joe [Alva, Poseidon CEO,] and Juliana [Saunders] there, and I also connected with them at a Rockheads event. I did a virtual reality tour at their booth and decided that was the machine for me. I got to meet Joe, Jon [Kaplan] and Juliana, and honestly, they were willing to work with me. They knew I was about to move facilities and that timing was critical. The fact that they listened and wanted to work with me in whatever way possible to make it successful was a huge factor in my decision.

SW: What qualities of the company’s equipment impressed you?

JR: First and foremost, it was not having to deal with a waterjet. Second, it was being able to put slabs on and get finished pieces off without double handling. There are no moving pieces from one cart to another where they could get damaged or broken. We go directly from slab to finished product. The power of the machine was also very impressive. It cuts with a 35-horsepower motor, and the speed along with the double-stack tooling on the cones, leads to less tool change time and overall better efficiency.

SW: Since investing in Poseidon’s machinery, what benefits have you experienced?

JR: We have experienced much higher quality in a shorter amount of time. Recently, we ran three slabs of quartzite with an Ogee edge, including an island, and processed everything start to finish in a little less than five hours. We were running our Ogee Position 3 at 300 inches per minute, which was incredible. Overall, my team is happy and loving it. They are moving material less, which makes it easier on their bodies, and we are producing high-quality products. The machine can do so much more than just countertops, so they are enjoying learning everything else it is capable of.

SW: Did you find that with the technology of the new machinery you needed less physical labor in the shop?

JR: Yes, absolutely. Like I said before, we are no longer double-handling material. We put it on the machine once, it runs and we get finished tops off the machine. That means far less material handling overall. Even with miters, the machine cuts them so well that we spend less time fixing or refining them because they come out flawlessly. It makes the entire mitering process much faster.

SW: What materials do you cut?

JR: We cut granite, marble, quartzite, engineered stone, porcelain and sintered stones.

SW: As a fabricator today, what do you find is one of your biggest challenges? 

JR: I would say the biggest challenge is consistently hitting the financial sweet spot. I know how much revenue we need to keep a small enough team while staying highly profitable. It is about making sure the margin of each job is protected, that jobs get done on time and without damage and staying focused on serving the right type of client in our smaller market for maximum ROI and profitability. In the past, the focus was simply on how many square feet we could complete. Now, it is all centered around the profitability of the company.

SW: Is there anything else you would like to share?

JR: Since getting the machine, we have had the pleasure of testing new materials coming into the market, like Italic by Radical and Mighty Slabs porcelain slab with the backer built into it. It has been a lot of fun cutting these materials, but what is even better is that the Poseidon team has worked with us hand in hand on determining what blades work best, what speeds, feed rates and RPMs should be used. They have been very involved in helping ensure these new products are successfully fabricated on Poseidon equipment and helping lead the industry with new products coming online.
