personal injury settlement
I am very satisfied with the settlement William Seiniger Jr. negotiated as compensation for my injury. William and his staff kept me advised of the status of my claim by phone, e-mail, text, and face to face meetings throughout the process. They also explained to me their strategy, answered all my questions, and explained how they determine what a fair and reasonable outcome would be.

Wrongful death
I was devastated when I lost my husband of 30 years and our son and daughter lost their father in a traffic accident. I knew in my heart it was not my husband's fault for his own death. It was a difficult case. Breck and his team were extremely considerate of the situation and my feelings. They were compassionate and helpful. They exhausted all avenues to help us. They were amazing! Thank you!!

Above Satisfactory Resolution with Exemplary Customer Service
Breck and his team did a fantastic job with obtaining a better-than-expected resolution to the legal/financial I was faced with. More than that, the level of personal customer service I received was exceptional. Breck always took the time to respond to me personally, frequently late into the evening and on weekends. Even though my small case undoubtedly represented a very minor part of the firm's caseload, they understood that to me it was very important. While I certainly hope not to need any further legal representation anytime in the near future, if I do, Seiniger Law is where I'm headed.

Excellent Attorney
Breck handeled our personal case. His staff is extremely professional and could answer any of our questions. They returned calls immediately with the proper information regarding our case. Breck was available for any questions we might have in our four year long case. Including weekend, I would highly recommend Seinger Law! Professional, thorough & caring for his clients.

There when I needed help
Breck made room in his schedule to meet with me when I had an important and time-sensitive need for legal advice. His consultation was friendly, thoughtful, frank and helpful. Thanks so much!

Integrity, Articulate, and Knowledgable
Breck is a rare gem in the legal world. He is equally passionate about his profession, his clients, justice, and the law. He never backs down from doing what is right, and works tirelessly to see that justice prevails. He cares a great deal about the truth and is honest about the process. He is extremely self aware, understands his limitations, and seeks out advice for areas that may be beyond his expertise ( although I am still not certain there is much his doesn't have know.) He is meticulous in thought and in writing and can often summarize issues within seconds. When you pay by the hour, this matters a great deal! I would recommend Breck to anyone with great confidence that they were getting the best representation in the field!

malpractice lawsuit
My wife and I are represented by Breck in a malpractice lawsuit. He has always worked hard and diligently on our case His staff is topnotch and super hard working, dedicated attorneys, paralegals, etc. As the lawsuit continues, we trust Breck's judgment, preparation, and his insight to try and solve the issues that have risen in this case. Breck is very honest and down to earth, which is appreciated in this day and age. He knows law and practices it well.

Knowledge and willingness to fight the system made all the difference.
Mr. Seiniger helped me with a personal injury case involving an automobile that rolled out of a carwash pinning my legs to a nearby vehicle. What I thought would be a clearcut case of negligence became a very complicated case with multiple attorneys fighting my claim. Complex and prolonged medical treatments, changing statutes and the carwash blaming car problems/owner vs. owner blaming carwash were just some of the problems. Seiniger Law was there all along the way. Mr. Seiniger kept me informed, advised me when needed and represented me at mediation. What a difference it made in the end. My case was settled to my satisfaction. I appreciated the care and concern of Breck Seiniger and the dedication of his team. I highly recommend them for any personal injury case.
