Immersion Health is based in St. Louis, Missouri.


Immersion Health was established in 2017 in partnership with the LifeSci Global group. LifeSci Global consists of LifeSci Strategic Consulting, focusing on increasing patient access to cutting-edge technologies, LifeSci Diagnostics, focusing on marketing genetic diagnostic/predictive testing, and LifeSci Therapeutics focusing on consulting and prescription solutions for providers and pharmacies. Immersion Health’s initial focus was providing the Healthcare industry with highly qualified, highly trained and fully compliant marketing, sales, and contract services team members.

Since its beginnings, Immersion Health has been recognized for its excellence in this space and has grown to include value adding products and services for both the healthcare and the consumer health markets. At the top of our list of successes is our partnership with VisionScope Technologies. As their only national distributor, reseller, and training partner, we are proud to be a driving force with VST demonstrating what we believe will be the new Gold Standard in office-based diagnostic needle arthroscopy.
