Providing Enhanced Levels of Care

CircleLink Health is a company of passionate clinicians, technologists and business people tackling the $600B problem of preventable chronic and post-acute complications. We’re building the world-class Care Management platform to enable providers while accelerating the shift to preventative care instead of status quo reactive care. Does this sound like the mission you’ve been looking to join? Apply here.
From the start, we’ve believed patients benefit most from personalized and provider-led follow-up between visits. We launched our diabetes module in 2010 (intelligent texting on behalf or Dr.s), and have since launched protocols in most major chronic conditions. Starting in 2015, we folded this expertise into our award-winning Care Management and Remote Patient Monitoring platform, manned by our amazing registered nurse network. This platform drives improved health and significant new provider profits.
