Client Testimonials

“Mr. Donn G. Fizer was the best thing I could have done after my accident. Not only was my case personal to Mr. Fizer. The results he produced were the absolute best I could have been rendered because of him! His performance showed simply and plainly that NO MATTER WHO THE LIEN HOLDERS WERE OR EXCUSES THEY MAY HAVE USED TO TAKE YOUR MONEY/SETTLEMENT, IT WAS NOT YOUR FAULT THEREFORE YOU DESERVE WHAT HE WORKED FOR YOU TO GET! More importantly, his character speaks for itself, which you will soon find out for yourself. Just remember, you didn’t ask to get hurt, why let these people pepper you with nonsense to innocently work you out of all that is yours by legal right? Fizer, LLC is the right choice. Winning % that speaks for itself. Million $ production from the attorney that handled right there in the office for what more could I say?”

— Angelica Laessig

“WONDERFUL ATTORNEY! The after math of being in an auto accident on the highway is very difficult and confusing. I highly recommend Fizer, LLC for your auto and home accidents. Was there for me every step of the way and made it so much more understandable. My back is still a wreck, and we are set to begin litigation. My husband and I have had a horrible experience with this accident, but this law firm has been patient and understanding. We were told upfront by everyone that it would take forever to see any result from the insurance company. I DO NOT doubt that if anyone can make something happen, it will be Don Fizer. Our original lawyer did have issues himself and was unable to properly serve our case. Fizer, LLC took charge and continued from here. We are ever so grateful for that! Forever grateful!”

— Quamyka Calvin, Prometheon Financial Consultants

“We are so grateful for the efforts and professionalism of Don Fizer [at Fizer, LLC] in finding the negligent party responsible for my husband’s accident on his way to work. He got hit on his motorcycle and the other driver slammed into him without a valid motorcycle license. We were surprised, shocked and relieved that Mr. Don Fizer did a very good investigation and found the other driver’s address and provided a photo of the “hit and run” car parked in his driveway. The insurance records revealed my husband was NOT at fault. Without Fizer representation, ongoing follow-up, and phenomenal persistence, we would not have known the other driver’s identity. I highly recommend Fizer, LLC.”

— Frank Carnemolla

“Too Bad your not my family lawyer. Great Job… Mr Fizer and his staff ensured me of better representation when I reluctantly went into signing a contract. That’s more than I got from my prior lawyer… So far that contract reference played out just as mr Fizer said it would.. He’s great …”

— Donnie Terrasse
