I used the Law Offices of William Trevillian, P.A after being involved in a vehicle accident and William was so amazing at helping me every step of the way and answered any and every question I had about the process.

I would like to sincerely thank the law offices of William Trevillian and staff for the expert service and attention of law given to me this week. Mr. Trevillian handled my legal matters swiftly and efficiently with short notice from me.

I have had Bill Jr represent me on a couple of matters where I was involved in a traffic accident. I felt he had my back, was honest as to what to expect, and was a very competent attorney. A great experience both times.
