About Us


Based on his personal frustrations with existing tools in his spinal surgery practice, Jeff Kleiner, M.D. founded Kleiner Device Labs in March 2013 together with John Grimberg and Harris Kirschner. Kleiner Device Labs goals are to improve the tools available to spine surgeons making procedures easier, faster and with higher success rates, to improve outcomes for patients, and to lower costs for hospitals, employers and insurers.


Jeff Kleiner, MD

President & CEO

Dr. Kleiner trained at Stanford University, University of Colorado, Rush/Presbyterian-St. Luke’s Hospital in Chicago and University of CA at San Diego for pre-medical, medical and residency training.  He was a NIH postdoctoral fellow in the biochemistry of tendons and ligaments and fellowship trained in adult and pediatric reconstructive spinal surgery. His practice is limited to the care and treatment of spinal disorders. 

Frustration with existing tools and instrumentation systems led him to develop a suite of tools and techniques which allow performance of open and minimally invasive spinal surgery to be safer, easier and more efficient. Multiple patented and patent pending systems make up the intellectual property of Kleiner Device Labs.
