A brief history...

In the winter of 2012, motivated by a wallowing economy, family hardship, and nudges from powersports friends and dealers, Brandi and Sam Dantzler launched the first iteration of the industry-specific online training platform, Sam’s Powersports Garage. With decades of industry knowledge, a lifetime of passion around powersports, and a natural entertaining charisma, Sam was a perfect fit for the trainer role. Brandi’s business sense and diverse organization and management skills cemented her role as primary owner and operations manager. Peter Wigand - who’s talent, loyalty, and wit grace the company still – joined the duo as videographer fresh out of film school.

In 2014, encouraged by the success of the Garage, Brandi and Sam expanded their training offerings to the Marine Industry with Sam’s Watersports Dock. The following years saw steady growth in the business and the addition of Siobhan Roder-Cox to the team as Brandi’s right-hand woman.

After years of working within the constraints of existing third-party training hosting solutions, Brandi determined that the only way to achieve her vision of a platform with unique, industry-oriented features, an excellent user experience, and unrestrained design/development freedom, was to create that platform from scratch. In 2016, TJ Mahlin joined the team to lead up the new platform design and business re-branding as Wheelhouse College.

No longer constrained by external development limitations, Wheelhouse quickly rolled additional content and products, including Sam’s Peloton for the cycling industry, and OEM branded training portals for major players in the powersports and marine industries. This growth continues today with a steady flow of updates and enhancements to our custom learning management system, new content for existing subscription products, the expansion of product offerings, and creative collaboration with our Industry partners.
