Before Oryzon owned a single refrigerated truck, two families were already living the cold chain, without knowing they were building toward it.

On one side, a cattleman in Mexico raised, fed, and brought his herd from farm to table, learning at the very first link what it takes to keep perishable product whole. On the other, a refrigeration specialist spent a lifetime building the systems keeping product cold — the same units riding behind a reefer truck today. One family understood the product. The other understood the cold. Neither set out to start a transportation company. They were simply doing the work, raising their children inside it, and passing down everything they knew.

One family understood the product. The other understood the cold.

Oryzon is where the two finally meet. Look closely at the name and you will find the reason. The RYZ at its heart carries both families: Ramirez and Zamora — two surnames, two histories, and two sets of hands joined under one purpose.

So before we tell you what we deliver, let us tell you who we are. It is the most honest answer to why you should choose us.

A Family Quietly Gathered Every Piece of the Cold Chain

Most cold-transport companies start with a truck and a load board. Oryzon started with people who have spent their whole lives in the work, long before anyone thought to put a name on it.

Myrna's Side: Diesel, Cattle, and a Respect for the Road

You have already met Myrna's father, Tino Jr., as the cattleman. Before either calling, though, both he and his own father, Tino Sr., spent years working the oilfields as full-time drillers — hard, exacting work that taught them firsthand what fuel costs to pull from the ground. Tino Jr. has since spent over twenty years as a full-time diesel mechanic at Schneider National, one of the largest and most safety-driven carriers in the country. Schneider built its name on safety, and Tino Jr. has lived by it every day. To him, speed has never been the point: every vehicle on the road should be safe for the driver and for the families traveling alongside it. His rule is simple. Every semi leaving his shop must be safe enough to drive beside his own children. Before Schneider, he earned a vocational degree in mechanics and made his living keeping vehicles running. As his eldest, Myrna grew up around engines, specs, and the discipline of caring for a machine properly. She does not simply read a maintenance report. She understands the heart of a truck and what it takes to keep it healthy.

Every semi leaving his shop must be safe enough to drive beside his own children.

Tino Jr.'s story does not stop at the shop. On his ranch in Mexico, he was a cattleman who raised, fed, and brought hundreds of head of cattle from farm to table through the 1990s and early 2000s. The ranch was not run informally. It was registered with ANGADI, Mexico's national association for diversified ranching, operating under a recognized standard for the legal, sustainable use of land and livestock. Myrna was part of it. In her early summers, she worked the ranch alongside her brother: feeding the animals, tending to their medical care, gathering the herd, and loading them for transport to market. She learned the work of keeping perishable product healthy at the very first link, long before a trailer ever entered the picture. The legacy passed down from Tino Jr.'s own father, Tino Sr., who left the oilfields to become a full-time cattleman from the 1960s through the 1990s, working his own ranch. When rising violence in Mexico made ranching untenable, Tino Jr. chose to reinvest in his children's future — in Oryzon. He understands cold chain from the side most carriers never see: as the man who raised the product before it ever reached a trailer.

Myrna's brother, Tino III, has managed several logistics warehouses in Laredo for over twelve years, analyzing operations and consistently meeting and surpassing expectations with integrity. He has handled critical, on-demand 24/7 air cargo, expedited ground shipments, and repacking contracts on one of the busiest trade corridors in North America. During the 2020 pandemic surge, his operation moved some of the heaviest air-cargo volume the state had seen, and on one 2016 stretch the inbound freight his team generated nearly overwhelmed a receiving airport. Through all of it, he has watched demand for refrigerated logistics go unmet, turning away business again and again because his operation cannot offer it. He knows exactly where the cold freight is, and he is positioned to help bring it to Oryzon.

Rounding out Myrna's side is her sister-in-law, Lily, an accountant at a nationally recognized bank headquartered in Texas. For nearly a decade she has kept an operation's finances clean and defensible: preparing financial reports, reconciling accounts, reviewing transactions and flagging anything out of place, recording journal entries, and handling the routine day-to-day bookkeeping. Lily is ready to bring this experience to Oryzon as Myrna's right hand on the finance side, keeping the company running and the books clean.

Michael's Side: Refrigeration, Paperwork, and Miles Behind the Wheel

Michael's father, Adrian, has been an entrepreneur his entire life and a true man of all trades, though his specialty is refrigeration. He has built and designed massive refrigerated warehouses from the ground up, and Michael was his right hand through all of it: setting panels, laying flooring, and learning everything it takes to get a refrigerated facility calibrated, operational, and running to a client's exact specifications. Adrian holds manufacturer certifications from the names worth knowing, including Carrier, Thermo King, Sub-Zero, and Wolf — meaning he was trained and trusted to service high-end refrigeration systems to each maker's exacting standard. Today he runs his own company with more than ten technicians working across Texas and into Louisiana. This reach is one reason for our confidence: if a load ever needs emergency refrigeration service, we have a trusted network ready to respond.

Michael's aunt, Martha, effectively ran an entire logistics company from top to bottom: operations, staffing, finances, compliance, and the daily decisions keeping a business moving, while the owner handled only marketing. A central part of her role was navigating the aduana — Mexican customs — and the relentless documentation cross-border freight demands: import and export filings, manifests, duties, and the exacting paperwork deciding whether a shipment clears or sits. Michael spent his summers working alongside her, learning this documentation discipline firsthand.

Michael's uncle, Luis, spent many years as a truck driver before retiring to focus on his family. Across his career he ran it all: dry freight, refrigerated loads, heavy haul, and oversized loads, nationally and internationally, giving the family a driver's-eye understanding of every kind of freight on the road.

The Houston-to-Laredo run is not a route we looked up on a map. It is a road our families have traveled for generations.

Our Advisor: Alice, Who Built a Transportation Company Across Two Countries

Michael's aunt Alice serves as an advisor to Oryzon, and few people bring more directly relevant experience. She built her own transportation company from Mexico into the United States, found a home here, and continues to operate internationally. Over more than twenty years as an owner, she ran a fleet reaching more than sixty semis at its peak. She has done exactly what we are setting out to do, and she is in our corner.

The Missing Piece Was Us

Between the two families sat nearly every skill a cold-chain carrier could need: the mechanic, the cattleman, the refrigeration specialist, the logistics manager, the driver, and the owner who had already done it. What the picture still needed was someone to protect the work legally and keep it honest financially. So we devoted our education to becoming exactly that.

Michael is our COO and runs legal. He is a commercial and defense attorney whose work includes defending trucking companies in 18-wheeler accident cases, which means he has studied, from the courtroom side, precisely how these trucks cause trouble and how to keep a fleet clear of it. He came up working refrigeration alongside his father, so he understands a reefer unit as fluently as he understands a contract.

Myrna is our CFO. She built her career at Deloitte, one of the four largest accounting and auditing firms in the world, where she audited corporate finances against Sarbanes-Oxley, the federal standard for proving a company's numbers are accurate. She holds an MBA and is a Certified Internal Auditor, and she runs Oryzon by the same discipline: every process documented, every number defensible, and every risk caught early. She also grew up loading cattle on her father's ranch, so she understands perishable cargo at its source, not merely as a line on a spreadsheet.

We did not pursue those paths to climb away from where we came from. We pursued them to supply the one piece the family had not yet placed, and to build something able to hold both sides together. An owner who understands the law protecting your load and the machine keeping it cold, paired with an owner who refuses to let a single number slip, standing on three generations of people who lived this work. The combination does not exist down the street. It barely exists in the industry.

At Its Heart, Oryzon Is a Union of Two Families

The trades and the professions, the ranch and the courtroom, the shop floor and the audit desk: everyone has a place in this company, and every load we carry honors what they built. The name says it plainly. At the heart of Oryzon sits RYZ, holding both families: Ramirez and Zamora. Read it again and it says something more, a single instruction we gave ourselves: rise. The ON pushes it onward. Rise on, toward the horizon the whole word was built around. We are not working toward a finish line. We are working toward an infinite horizon, building a company able to outlast us and to leave a legacy for the generations coming after — exactly as our families did for us.

What This Means for You

Everything you have just read is not a backstory. It is the reason your load is safer with us. When a cattleman spends a lifetime keeping a herd whole from farm to table, his daughter does not treat your produce as boxes on a pallet. When a mechanic refuses to let an unsafe truck leave his shop, his rule lives on in the fleet carrying your freight. When a refrigeration specialist builds the very units riding behind a reefer, his son knows the difference between a unit running and a unit failing. Every link our families spent decades mastering is now standing between your product and everything able to go wrong.

Notice, too, what runs through every one of those stories. The ranch was registered with a national association and run to its standard. The refrigeration work carried manufacturer certifications from the most demanding names in the industry. Long before compliance was something a client asked us to prove, it was simply how our families worked.

We did not learn to respect the rules. We were raised inside them.
The Oryzon Edge

So yes, we are compliant. Yes, we monitor temperature in real time and hit our delivery windows. Every serious carrier should, and we treat those as the floor, not the ceiling. What our story adds is the part you cannot audit on a rate sheet: people who understand, in their hands and not merely on paper, what your product is worth and what it costs you when it arrives wrong. People in our family pulled fuel from the ground themselves, so when we price a lane, we price it honestly — never padding a number you should not have to pay.

Because when your product arrives exactly as promised, your customer trusts you a little more. The reorder comes. The relationship deepens. To us, a refrigerated trailer is never simply freight. It carries your name, your promise, and your next order riding in the back. This is why "delivered" is not our standard. Protecting what rides inside is — every load, every requirement, no exceptions — because protecting your promise is the one thing our family was built, across three generations, to do.

We Protect Your Promise

Other carriers move cold freight. We protect the reputation riding inside it. Choose the carrier built, top to bottom and across three generations, to make sure your promise arrives intact.
