Our Philosophy

Since its inception, the Firm has demanded that the lawyers of Deasey, Mahoney & Valentini, Ltd. provide superior, cost-effective legal representation to a myriad of clients. Our overriding philosophy has always been a simple one: to provide exceptional, responsive service to our clients at a reasonable cost. We implement this philosophy every day through adherence to several guiding principles:

Personal Attention

The structure of the Firm permits our senior litigators to give their personal attention to every case in litigation. A senior attorney will be involved in all phases of the case, from pleadings through trial.

Efficient Use of Personnel

Upon initial assignment, a partner will review the case with the client, and they will reach an agreement regarding which attorney is best suited to handle the case. In order to reduce costs, less senior attorneys may be recommended to handle pleadings, legal research, and basic discovery. Experienced paralegals may also assist at various stages of discovery and trial preparation for cost-effective results.

Mutual Decision Making

Most importantly, all significant decisions in the handling of every case at Deasey, Mahoney & Valentini, Ltd. are determined after a thorough and mutual discussion with the client. We pledge to keep our clients updated and involved in all major decisions throughout the litigation process. Our goal is to provide personal attention and superior legal service.

Technology at Trial

We can offer our clients the latest technological tools for presenting evidence at trial in a powerful and fluid format that keeps the jury focused and interested. At trial, our attorneys are equipped with visual technology that allows them to quickly refer to key documents, photographs, computer animations, charts and graphs. These tools enable our attorneys to highlight and manipulate exhibits for emphasis or comparison. We illustrate the case.
