Great team of professionals
William Mattar accepted my difficult case after other law firms refused it, due to me being an "eggshell client." From start to finish, Megan always provided value added service by responding to my questions and/or concerns expeditiously; by the close of business or within 24 hours. As I conclude, I would like to thank William Matter, Megan, and their team of consummate, dedicated and engaged professionals. You all are truly AWESOME. Remember, It is not the final settlement that matters, as it is the amount of professionalism that is priceless! Don't hesitate, call 444-4444. You will not regret it!

You just never know
I was involved in an auto accident and the driver of the other car had run a stop sign. He then T-Boned us, my son and had been taken to a local hospital and my wife was fine. When reading the police report we seen that the driver that hit us also had the same insurance company as us. I then became worried that the insurance company would not be fair and cover my medical expenses and repairs needed on my car. After speaking with some family members they recommended hiring a attorney. I then called William Mattar. I met with one of the attorneys and decided it would be best if retained their service’s. I was not happy about this because I deal with attorneys at work all the time. Most attorneys will never call you back, keep you up to date with the case. The only time they call is when they want more money. NOT William Mattar my attorney Casey was Great she called with updates questions and more. Her assistant Kathy was even better she call me weekly in the beginning then COVID hit and my doctors slowed down the process but Kathy kept calling me with updates and not long after we had a settlement offer and after some negotiations we settled. THIS FIRM WAS GREAT! I hope I never need a lawyer again bu.t if I do I will call William Mattar.

Exceptionally pleseant experience
I was hit by a car while riding my bicycle back in 2019 and they talked with me and helped me out in getting the ball rolling towards a potential case. In the end, my injuries were not serious enough to file any claims of significance other than getting my hospital bills covered by the other party's insurance. Everyone I interacted with and spoke with was always kind and professional. The firm even helped me out a few months later by helping to guide me in the right direction when the other party's insurance was dragging their feet on paying my medical bills. I will always recommend the William Mattar law firm when I come across anyone who was injured in an auto accident.

Automobile accident/Surgery
I was rear-ended in November 2019, and had surgery in 2020 for a traumatic spine injury. Everyone connected with my case couldn't have been more patient and sympathetic as they handled my case. Every question that I had was answered .... they were very understanding as I was recovering from not only one surgery....but two. (I fell during my recovery, and had surgery on my wrist). I would not hesitate to recommend Wm Mattar's Team to assist anyone who has had a car accident. Many thanks to each and every person who helped settle this end of my recovery. Many Blessings :-)
