The Chinese character, “未” means both “sheep” and “yet to / pre.” At SheepMedical, we operate under the symbol of the sheep. With preventative care at our core, we are creating health solutions for today’s problems, and anything tomorrow brings.  

We're a medical technology company promoting the digital transformation of orthodontics and preventative care. Our story began with the fastest aging, but healthiest population in the world – Japan. With our preventative care model, SheepMedical provides health services to extend global life expectancy.

SheepMedical was founded in 2017. Our unique perspective on aging populations challenges the increasing global medical costs associated with preventable health issues. We continue to offer patients advanced health benefits and first-class care as we strive for longer life spans across the globe.
