Sigma One Group

Based in Neenah, Wisconsin, Sigma One Group has operated since the mid-1990s, positioning itself as an early developer of outsourced marketing departments for law firms. Attorneys and legal practices make up a core part of its client base, though its services extend to businesses seeking a broader online presence. The agency describes itself as acting as an extension of a client's marketing department, offering ongoing support alongside project-based work, and emphasizes personal service and quick turnaround as part of how it engages with clients. Its declared service list spans search engine optimization, pay-per-click advertising, social media marketing, content marketing, web design, web development, and mobile app development. On the website side, the agency states it builds hand-crafted, CSS-driven websites that are browser-tested, distinguishing this approach from WordPress-based or app/module-driven site builders. For online marketing, it references the use of keywords, key phrases, and inbound and outbound linking as components of search visibility work, framing SEO as central to helping clients get found online. The agency also lists online hosting among its offerings, alongside strategy and consulting work that precedes design and development on client projects.
