The firm operates with approximately 10 employees from a single Cherry Hill office, serving a two-state regional footprint. There is no public listing, no disclosed funding, no M&A activity, and no parent company — consistent with an independently held professional partnership-style practice.

• Marshall Dennehey: Large regional insurance defense and civil litigation firm with significant New Jersey and Pennsylvania presence. Comparable because it competes for the same insurance carrier panel work and corporate defense engagements, but at substantially greater scale and geographic breadth.
• Archer & Greiner: Full-service NJ-based firm with a substantial litigation practice serving corporate, municipal, and institutional clients. Comparable client overlap in NJ civil defense, though broader in scope (transactional, regulatory) than the subject firm.

• Cipriani & Werner: Regional insurance defense and civil litigation firm with Mid-Atlantic offices. Comparable practice mix (insurance defense, commercial, employment) and similar target client base of insurers and corporate defendants.
• Rawle & Henderson: Pennsylvania-founded civil litigation and insurance defense firm with NJ presence. Comparable because it serves the same insurance carrier and corporate defense clientele across the same Mid-Atlantic jurisdictions.
• White and Williams: Philadelphia-based civil litigation and insurance defense firm with NJ presence. Comparable because it competes for the same Fortune 500, insurer, and municipal defense work across the Mid-Atlantic region.
