Jaime Casado of RETO Health: The Future of Healthcare Is Already Here

“I was a professional athlete. Then, at 17, a car hit me and ended my sports career. That day, I almost arrived dead at the hospital in cardiac arrest, with open fractures, broken bones everywhere. Two of the best surgeons in Europe saved my life. That accident changed everything.”

For Jaime, founder of RETO Health, survival was only the beginning. Out of tragedy, he built one of the most ambitious visions for the future of medicine in America.

The Birth of RETO Health

What began as personal training and a meal prep business has evolved into a world-first health concept in Miami. RETO Health is not a gym, not a clinic, and not a spa—it’s a completely new category of preventive medicine, merging science, technology, and wellness into one personalized ecosystem. Integrating a model of anti-aging and regenerative medicine using cutting-edge treatments like stem cells, exosomes, and cellular therapies, they quite literally help you repair, recover, and regenerate from the inside out.

“For us, RETO is like a pyramid,” Jaime explains. “You start with the assessment and then you begin to build the rest of the protocols the foundation of your health.”

That assessment is unlike anything else in the U.S. Patients undergo DEXA scans for bone and muscle analysis, gas exchange studies for lung and cellular function, and full blood panels for hormonal, vitamin, and mineral mapping.

“We measure everything,” Jaime says. “Your cells, your heart, your lungs, your brain, your nervous system, your diaphragm, your skeletal system—everything.”

From there, RETO designs tailor-made protocols across four main departments: exercise, nutrition, psychology, and physical therapy.

“The psychology department is one of the most important pillars. You can go to a gym and have a nutritionist, but it all starts within you,” Casado emphasizes.

Technology That No One Else Has

But what truly sets RETO apart is its biohacking and longevity departments, where the future of healthcare is already happening.

“We bring the latest technology in the world, the best, here,” Jaime says proudly.

That includes the only Japanese infrared Sauna Iyashi Dôme in the United States, and a hyperbaric chamber designed by RETO with the latest technology, the best on the market.

After visiting the center, I realized it was no exaggeration. Walking in felt like stepping onto the set of a sci-fi film, the future of medicine unfolding before my eyes, with genetic testing, force plates, and real-time ultrasounds at my fingertips.

The innovations don’t stop there. RETO was the first in Florida to perform advanced stem cell and exosome protocols after the new law was signed on July 1st, 2025.

“We were the first to do the most advanced exosome protocol, and it was for a player from the New York Giants,” Jaime recalls. “It was spectacular.”

Today, RETO works with top athletes from the NFL, NBA, Real Madrid players and UFC, as well as corporations investing in customized executive health programs.

From Viral Transformation to Global Recognition

RETO’s breakthrough moment came when Jaime worked with a basketball player whose nine-month transformation went viral.

“They compared him to Giannis Antetokounmpo and LeBron James,” Jaime says. “It was incredible. That’s when agencies, agents, and players started calling.”

The Proof Is In… Your Biological Age 

Even Jaime himself became a case study in RETO’s methods. After years of pushing his body to the edge, building his business, his nervous system was under strain. His own team built a protocol for him, blending grounding work, breathwork, biohacking, and longevity treatments.

The results? In just six months, Jaime’s biological age dropped by 11 years.

“My biological age came out as 19,” he says. “Right now, I have the greatest biological age difference of all patients and clients. That’s the power of what we do.”

The Vision of Tomorrow

Although Jaime does have the key to the city. Looking ahead, he sees RETO becoming much more than a Miami hub

“Our long-term vision is to shift the focus of people. Instead of looking first to a hospital, they’ll look to a preventive site,” he explains.

RETO plans to expand into a full-scale medical and hospitality destination, with specialists in oncology, cardiology, and respiratory health all powered by the world’s best technology.

For Jaime, the goal is simple yet radical: make healthcare proactive, not reactive.

“The Preventive Medicine Department has been one of the most important pillars for us,” he says. “It’s where we are seeking out the latest trends and techniques to enhance people’s health and everything we do here.”

The Future, Now

Jaime’s story is proof that out of crisis can come revolution. From a teenager clinging to life in Spain to a pioneer reshaping healthcare in Miami, his journey is nothing short of extraordinary.

“Whether it’s a great athlete, a corporation, or any person,” he says, “the first thing I’ve always wanted is to take care of the people I work with. That’s the future of medicine—personalized, preventive, and powered by the best technology in the world.”

And with RETO Health, that future is already here.
