Norwest Venture Partners (Norwest), a leading investment firm, today announced a $20 million investment in Onsite Dental LLC, a company bringing comprehensive dentistry directly to organizations and universities. Norwest General Partner Ryan A. Harris, M.D., Vice President Ryan McDonald, and David Willens, founder and former CEO of Gentle Dental, will join the Onsite Dental board of directors.

Onsite Dental was founded in 1997 to bring state-of-the-art, full-service dental care to the workplace and today is the national leader, serving some of the world's most respected employers, unions and universities. The company currently provides onsite dental care in fixed-site and mobile practices to more than 230,000 staff members at leading organizations in technology, manufacturing, healthcare, finance, entertainment and higher education.

Nearly 40 percent of Americans do not visit a dentist regularly. Studies show that patients who see a dentist annually have lower costs for diabetes, heart disease, stroke and low-birthweight babies compared to those who don't have annual dental visits. With its convenient onsite services, Onsite Dental helps organizations lower their long-term dental and overall health costs. Affiliated dentists are committed to evidence-based dentistry, taking advantage of the latest technologies and practices.

"Norwest's healthcare team focuses on research and outcome-based solutions to critical healthcare needs," said Dr. Ryan A. Harris, general partner at Norwest. "Onsite Dental stands out not only for its exceptional quality of dental care and patient satisfaction, but also because the company saves money for patients and employers, and delivers care in a convenient manner that saves time."

"Making high-quality dental care and an outstanding patient experience more accessible motivates patients to see their dentist regularly," said Ern Blackwelder, CEO of Onsite Dental. "Choosing the right dental partner is critical for an organization's overall wellness strategy, and Onsite Dental is privileged to be the clear industry leader. We are thrilled with Norwest's investment, which will help us expand nationally and continue to improve the support we provide to our affiliated dentists."
