Its headcount is reported in the 11–50 range, with approximately 16 named attorneys plus a supporting team of paralegals and staff.

GRGB provides legal representation across sixteen or more practice areas, organized horizontally by legal specialty rather than product tier.

The firm's business model is traditional professional services: revenue is generated through billable hours and contingency fee arrangements, with pricing determined per matter and not publicly disclosed. The go-to-market is sales-led and referral-driven, supplemented by a content marketing program built around the firm's Wisconsin Trial Lawyers Blog, social media presence, press releases, and community sponsorships. The firm has no proprietary technology stack and lists "professional legal services firm" as its core technology category. Client engagement is direct via phone (414-271-1440), website contact forms, and in-person consultations. The firm has no external investors, parent company, or public listing, and ownership is held among the partnership. GRGB has been consistently recognized by U.S. News & World Report (Best Law Firm, 2019–2026), Super Lawyers, Best Lawyers, the Wisconsin Law Journal (Power 30), and BizTimes among others.
