Working together to improve
community health outcomes.
Pioneers in public health detailing and program implementation.
As a key player in the deployment of the very first public health detailing program back in 2005, we’ve been championing the effectiveness of public health detailing to deliver key messages that improve clinical prevention services since the beginning. Our dedication to promoting public health and wellbeing is what drives us every day as we spread vital information to healthcare professionals and the communities they serve.
We’ve honed our skills, bolstered our expertise, and grown exponentially since those early days, and have been instrumental in the design and implementation of successful healthcare professional outreach programs for state and local public health departments, nonprofits, and health insurance and health services organizations throughout the country.
Today, we remain the only contract sales organization with a decades-long history of supporting municipalities with expert public health detailing programs as well as turnkey recruiting, temporary staffing and management of skilled public health representatives, training, CRM systems and reporting, and operational support. We take pride in the measurable improvements in health outcomes our health department clients have achieved through our partnerships.
A proven track record for delivering mission-critical outreach, education, and support.
Our management team has launched over 65 public health detailing initiatives for health departments nationwide. We have a deep understanding of how to deploy the right representatives to effectively educate and provide community outreach to physicians, nurses, pharmacists, and other health professionals. Carefully selected specialists visit local provider sites to conduct training sessions and distribute tools and resources to facilitate the adoption of evidence-based best practices in chronic disease prevention and management.
Quite simply, OnCall EOS is your go-to partner for the cost-effective deployment of public health detailers and other personnel to provide education and field research programs in all clinical disease states. Your goals are our goals.
