The Joovv Education Team

With a science-first approach, our education team ensures the Joovv content is well-researched and supported by published, peer-reviewed data.

Greg Pfiffner

Director of Research and Development

As Director of Research & Development for Joovv, Greg has spent 15+ years in project management and always brings both an engineer’s and an entrepreneur’s approach to research and problem-solving. Greg loves to drill down to the micro level, so he’s completely at home talking about cellular respiration and how light therapy excites the electrons in your mitochondria. Greg received a B.S. from Iowa State University.

Justin Strahan


Not just any man can take his wife's dream and make it a reality. This is just one of the reasons why Justin is so special. Justin's affinity for process and extreme attention to detail is why we are lucky to have him as head of R&D. The two words we would to describe Justin are intuitive and thorough. Prior to inventing and developing the Joovv, he spent his career as an engineer managing design and development teams.

Scott Nelson


Scott is the impetus, power, and energy that set Joovv in motion. As head of commercialization, his ability to metabolize information quickly makes him an irreplaceable asset. The two words we would use to describe Scott are efficient and personable. Prior to cofounding Joovv, he spent his entire professional career in leadership positions with some of the largest medical device companies in the world, including Medtronic, Covidien, Boston Scientific, and C.R. Bard.

The benefits of photobiomodulation have been proven in hundreds of clinical studies. With full-body therapy from Joovv, you can experience systemic benefits in the comfort of your own home. I use one myself and it comes highly recommended.
