Our History

As with most great stories, Healer Tech’s began with one of personal experience with the realization that healthcare needed something more.

  • October 2014

    When Founder & CEO, Fox Cheng, was still a Ph.D. student of Math in UCSD, he suffered from low back pain due to improper exercise movement and poor posture. During the treatment, he became intimately familiar with how Physical Therapy can elevate one’s health and the human experience.

  • December 2014

    Fox began studying the neuromusculoskeletal system and discovered that EMG is the best technology to detect the muscular activities. When combined with biofeedback, patients intuitively visualize their care experience and begin taking control over their healing process — gaining immediate trust for the attending clinician.

  • March 2015

    Fox’s Physical Therapist friend and colleague informed him that EMGs are hard to use; moreover, for clinical use, the setup time is too costly and the machines involved are far too expensive. Fox’s immediate thought: “Let’s develop an affordable and easy to use EMG system for clinics!”

  • May 2015

    The founding team was established along with Healer Tech as a company. Ideas were put into design, practice, refinement, and production. And, the rest… is now, HERE!

As a mother of a toddler girl, I realize that to bring our newly developed product to the PT industry will not only help the adult rehab population but also the kids who are undergoing recovery from medical need and help them get back to their playful childhood life as soon as possible.
