Our Mission

We aim to merge cutting-edge and contemporary medicine as individualized treatment protocols to reverse the flow of time for our patients with our holistic approach.

Stairway to Eternal Youth

The story of London Regenerative Institute started with two scientists, Steven Cohen and Tunc Tiryaki, who have dedicated much of their professional career to provide the keys to a longer and healthier life in search of eternal youth.

2006 was a milestone when Dr Cohen and Dr Tiryaki started working on expanding the possibilities of regenerative therapies with fat-derived stem cells. Their longevity journey brought them to collaborate with Cytori Therapeutics, Inc. – San Diego.
