Co-Founder, Chairman of the Board
Gentera's co-founder and Chairman of the Board, Louis Arriola believes regenerative medicine is the future -- and sees his role as providing a platform to the doctors of Gentera to help patients to live a "more balanced and healthier life."
"As I started to age, I always looked for an alternative to conventional medicine. When I found regenerative medicine, I discovered that not too many people knew about it. So, my goal was to help others to know that aging is not as bad if your body is in balance," he says.
Arriola brings a successful background as a strategic business professional and financier to Gentera. In 2016, the global telecommunications he built sold for over $300 million. With his wife, he owns the Los Angeles-based NYLA Productions, as well as Trionx, a real estate development company.
Gentera's co-founder was considering surgery when a shoulder surgery irritated him during workouts. He was educated on cell therapy and regenerative medicine, which cured his injury. "I knew then that I had to let other people know there were alternatives," he says. "It's very gratifying to know that I'm helping people."
