A defining moment in Dr. Greene’s career was his decision to leave clinical practice and focus entirely on innovation and education. “I’ve never been a fan of just settling for the status quo. Innovation is a cornerstone of what makes America great,” he reflects. This philosophy has driven R3 Stem Cell’s mission to provide affordable, high-quality regenerative care and to demystify stem cell therapies through comprehensive training courses and educational content for both providers and patients.
Dr. Greene’s work has garnered international recognition, including a feature on the cover of Corporate Vision magazine, where his commitment to affordable, accessible regenerative therapies was spotlighted. His impact extends beyond business metrics – he is known for his compassionate approach, always prioritizing patient education and ethical practice.
Outside of his professional life, Dr. Greene is inspired by the words of Maya Angelou: “My mission in life is not merely to survive, but to thrive; and to do so with some passion, some compassion, some humor, and some style”. He brings this ethos to his daily work, fostering a culture of innovation, empathy, and continuous learning.
When he’s not leading global healthcare initiatives, Dr. Greene enjoys sharing insights on social media, connecting with colleagues, and pursuing personal interests that keep him grounded and inspired.

Regenerative medicine is a relatively new and rapidly evolving field in the treatment of pain management, chronic disease, and injuries previously treatable with only surgery. Stem cell therapy has gained the attention of the scientific community over the past few decades, first with investigational research
Human amniotic cells have been used over the past 50 years as a diagnostic tool for prenatal diagnosis of genetic abnormalities in the fetus. Over the past 5 years, however, the potential for using stem cells derived from amniotic fluid has become a reality, especially
Amniotic fluid is the protective liquid that is contained within the amniotic sac of a pregnant mother. Amniotic fluid originates from the mother’s plasma and passes through the fetal membranes by way of osmotic and hydrostatic forces. It is important that the fetus inhales and
