What Makes Working with Us Different
You Talk Directly to Your Attorney. At Hennessey Law Firm, you will have direct access to your attorney throughout your case.
Our paralegals and case managers assist with documentation and day-to-day coordination, but legal strategy, settlement decisions, and case direction come directly from the attorney handling your file.
Every client is assigned a primary attorney responsible for their case and a designated case manager for daily questions.
You will always know exactly who to call—and you will never be transferred from person to person without clarity.
We are a focused, high-touch law firm—not a call center. Unlike nationwide firms that advertise on television and then hand your file to a junior associate you never meet, we personally select and handle each case.
We Advance All Costs—You Pay Nothing Unless We Win
Hennessey Law Firm works on a contingency fee basis, and we advance all litigation expenses including independent medical evaluations, medical records, expert opinions, and any other costs necessary to build your case. You are never asked to pay anything out of pocket. If we do not recover compensation for you, you owe us nothing.
We Keep You Informed
We believe communication reduces stress. You will receive updates whenever there is meaningful activity on your case—including medical developments, settlement negotiations, court settings, and legal filings. We encourage our clients to reach out with questions at any time, and we do not impose barriers to communication. When you call our office, you get answers.
A Practice Built on Workers’ Compensation
Well over 90% of our practice is devoted exclusively to workers’ compensation in Missouri and Illinois. We are not a firm that dabbles in work comp between car accident cases. This is our specialty, and it has been for more than three decades. That focus means we know the system, and we know how to get results for injured workers.
