One Medical Group, the fastest-growing primary care system in the country, today announced that it has raised $40 million of growth capital to expand to new markets and meet the critical needs of employers for an affordable care delivery solution. The round was led by Redmile Group, with participation from current institutional investors.

One Medical Group is the fastest-growing primary care network in the country.

'We started One Medical to build a better primary care delivery model - one that uses technology to deliver higher-quality care and service more affordably,' said Tom Lee MD, the company's founder and CEO. 'With our recent expansion into the enterprise, employers are discovering that our model can help them lower their overall health care costs while giving their employees turnkey access to quality primary care that they love.'

One Medical's technology-enabled approach to primary care gives health professionals the time and tools necessary to make smarter decisions, while empowering patients to better manage their own health. In addition, it offers top primary care physicians the opportunity to practice medicine in a more sustainable model of practice, focusing more of their time on patients rather than paperwork.

The funding news comes following a breakthrough year for One Medical. The company added seven new offices and grew its member base by over 50 percent in 2013, while also launching new telehealth services via Google Helpouts. In addition, the company recently announced that over 40 companies are now enrolled in its employee health benefit program, including Adobe, Doximity, Fitbit, NBCUniversal, On Deck Capital, Percolate, Quantcast, Sequoia Benefits, Uber and Wanelo.
