Our Story


ProSites was founded in 2003 after a simple observation: there was no easy way for dentists to get a high-quality, compelling website which they could edit at any time. And with that thought, Lance McCollough launched ProSites.

ProSites was the first dental website design company to have a content management system (CMS) that gave dentists greater control to edit their website in seconds, with a simple “point and click.”

As Internet trends evolved, we expanded our services to deliver a complete online marketing solution for dental and medical professionals that’s built with the purpose of bringing them new patients.

Today, with our powerful and comprehensive set of website design and Internet marketing services, dental and medical practices can attract, engage, and connect with patients by delivering an ideal experience and lasting impression online.
