Attorney Information

Overview

Adjusting to life at home after serving with the U.S. Armed Forces is difficult - especially if you have sustained an injury or are suffering from a mental health condition such as post-traumatic stress disorder (PTSD). Many veterans are wrongfully denied disability benefits or receive less compensation than they should, which prolongs the adjustment. We believe that after you serve your country, your country should be prepared to serve you.

Mattar LLC is an advocacy group and veterans' benefits service provider in Williamsville, New York comprised of VA-accredited advocates. We help veterans and their loved ones nationwide learn more about their eligibility for service-connected compensation and other post-service resources by navigating the appeals process. Our nationwide network gives veterans and their families a platform to stand on when they have been denied the benefits that they deserve.

Our trained and highly skilled professionals focus on veterans' disability benefits exclusively. We are experienced with all types of veterans' disability claims, including PTSD, as well as other mental conditions, traumatic brain injury (TBI), conditions related to Agent Orange exposure, such as Diabetes Type II and Ischemic Heart disease, sexual trauma, conditions related to Camp Lejeune water contamination, among many others. Our advocates stay up to date on changes in VA policy and procedure so that we can fight more aggressively to help you and your family secure the benefits that you are entitled to.

Visit Mattar LLC's website for more information, or call 877-777-4021 to speak with one of our knowledgeable veterans' advocates for assistance. We offer free initial consultations.
