Personal Injury Matters

Suffering from a serious injury is a terrible reality. Not only does a serious injury impact your life physically, it can take its toll financially and emotionally. If you are injured because of another’s wrongdoing, you may be entitled to compensation for all of your resulting losses. As you recover, our firm will fight for your rights. Trombly & Singer, PLLC handles a wide range of personal injury matters, including:

Our Approach

The cornerstone of Trombly & Singer’s success is the determination to provide clients with the effective legal services they need and the human touch they deserve.
We prepare our cases on the assumption that every matter will need to go to trial even though many settle without the need for court. A reasonable settlement, when it can be achieved, eliminates the uncertainty of a trial while avoiding the emotional turmoil of litigation.

We do not delegate responsibility to a lesser-experienced attorney. The attorney responsible for your case will be involved from the initial investigation, through discovery, all court proceedings, mediation and, if necessary, through the trial. Your attorney will know your case inside and out from beginning to end.

At Trombly & Singer, PLLC, you are not just a number. Your case is as important as the last and the next.
