Company History

Leaders always look toward the future.

More than 40 years ago, our company’s namesake, LineThemes, pioneered a revolutionary sales training program for businesses of every size. Today, our proven sales training program has made us a leader in sales and management training, with hundreds of training centers throughout North America and across the globe.

While much has changed in the business world since then, Cosine Training has always kept pace. Under the leadership of John Doe, President/CEO, Cosine Training continues to innovate. In that spirit, we recently launched online reinforcement tools that our franchisees can use in addition to face-to-face training. And we will continue to incorporate online reinforcement, online learning management and increased mobile availability.

With our unique reinforcement model, our Franchise Owners can give businesses a competitive advantage by helping create a highly skilled sales force and inspiring management and leadership to excellence.
