Editor's Review

VerifiedLawFirms editorial

Focus and practice areas

The firm describes itself as a business law and litigation practice, and its stated work bears that out. It handles commercial litigation, corporate and mergers and acquisitions, commercial services and restructuring, construction, intellectual property, and labor and employment. Those six areas cover much of what a company meets over its life, from formation and deals to disputes and workforce questions.

What stands out is the pairing of transactional and courtroom work under one roof. A client can, in principle, bring a contract to be drafted and a dispute to be argued to the same place. That breadth is common among firms of this size, and here it is backed by the practice list the firm publishes rather than by a slogan.

An added immigration practice

More recently, the firm established an immigration practice. This came through the addition of the law firm of Henin-Clark P.A., tied to its Orlando area presence. For a business-focused firm, immigration work often connects to hiring and moving staff across borders, so the addition fits the wider corporate and employment focus rather than sitting apart from it.

Where the firm works

Reach is one of the clearer facts on the firm's site. It reports more than 140 attorneys across eight offices. Those offices sit in Cleveland and Columbus in Ohio, Naples, Fort Myers, Tampa and Sarasota in Florida, San Diego in California, and Chicago in Illinois.

The contact pages add a couple of further locations, including Westlake in Ohio and a Winter Park office serving the Orlando area in Florida. The pattern is a firm rooted in Ohio that has extended south into Florida and west to California, with a Midwest presence in Chicago. For a business dealing with the same firm in more than one state, that spread is a practical point in its favour.

The firm also states that its work reaches beyond the country. It points to recent matters involving Western Europe, the Pacific Rim, and Latin America. That reads as a firm whose clients trade abroad, which lines up with a corporate and M&A practice.

What the outside record shows

VerifiedLawFirms weighs evidence over advertising, so mentions from outside the firm carry weight here. The firm states that The National Law Journal counts it in The National Law Journal's NLJ 500 ranking of U.S. law firms. Size is not the same as quality, but it does tell a prospective client something about staffing depth and staying power.

The firm also reports that Chambers USA has ranked its work in several areas: commercial litigation, corporate and M&A, commercial services and restructuring, construction, intellectual property, and labor and employment. Chambers bases its rankings on research and interviews rather than paid placement, so a mention there reflects an outside read of the practice. In my opinion, the fact that the ranked areas match the firm's own list of core areas is a useful sign of consistency between what it claims and how it is seen by others.

How the firm presents itself

One thing a reader should note is what the reviewed pages leave out. On the pages our research covered, the firm did not name individual attorneys, set out their titles, or list their law schools and admission years. Firms of this size usually hold that detail on separate attorney profiles, so its absence on these pages is not a warning sign, though it does shape what this review can confirm.

Because of that, this review rests on the firm's stated structure and practice rather than on named lawyers. As a reviewer, I would treat the office count, the founding year, and the practice list as the firm's own account, and the National Law Journal and Chambers mentions as the outside checks on it. A client who wants to weigh specific lawyers will need to read the firm's attorney pages directly.

Who might find this firm a fit

The picture that emerges is a long-running business firm with a wide geographic base and a practice list built around company needs. A business owner in Ohio, Florida, California, or Illinois who wants both litigation and transactional help from one firm is the natural audience.

The 1920 founding gives it more than a century of operation, which matters to clients who value a firm with a long track of continuity. The mix of construction, intellectual property, and labor and employment work suggests it can serve companies that build and hire, not only those that buy and sell. The added immigration practice widens that further for employers who move people across borders.

For a client whose needs cross state lines or reach abroad, the office spread and the stated international matters are the relevant facts to check. In my opinion, the firm's clearest signal is the match between its own account of its work and the outside rankings that cover the same areas. That alignment, more than any single claim, is what a directory built on evidence is meant to surface.
