Trefoil Group

Company Overview

Trefoil Group is a Milwaukee-based marketing agency specializing in B2B performance acceleration for mid-market companies, particularly those in private equity portfolios. Founded in 1991 by Mary Scheibel, the firm has evolved from its origins as Scheibel Halaska into a strategic partner for businesses in manufacturing, packaging, plastics, logistics, and sustainable solutions sectors. ​
The agency’s approach combines strategic insight, creativity, and digital fluency to help clients overcome challenges, seize opportunities, and achieve growth. Their services encompass branding and strategy, website development, strategic communications and public relations, digital marketing strategies, sales enablement, and advertising.
In September 2024, Trefoil Group merged with BrandStar, a South Florida-based marketing firm, to enhance their capabilities in B2B marketing and expand their reach. This merger strengthens Trefoil Group’s position in delivering integrated marketing solutions to their clients. ​
With a team of experienced professionals, Trefoil Group is committed to delivering marketing programs grounded in strategy and designed to deliver business results. Their expertise and passion differentiate them from other agencies and drive greater returns for their clients. ​
