Let's Work Together

My Big Why… My dad suffered his first heart attack while I was in law school at Florida State University. All of a sudden, my plans to move back to South Florida changed. I knew I needed to be near my parents who were living in Atlanta at the time. My dad was one of the lucky ones who survived his heart attack. But his physical health was slowed down and I wanted to spend time near him to help him and my mom. After working as a security guard for many years, Dad was unable to do the work he had done in the past. Without his SSI and the Medicaid that came with it, dad would have been unable to afford the medications that kept him alive. I know on a very personal level how important it is to my clients and their families that they receive the benefits they deserve. That’s why I love what I do and why it’s important to me that my office treats my clients with the kindness and respect they deserve.

As far back as I can remember… My sister always struggled with challenges that other people didn’t have. She is learning disabled and she wasn’t able to hold a full time job because of the challenges she faced. As her big brother, I always looked out for her and helped her through the many obstacles she’s had to deal with in life. Now as a social security disability attorney, I get to help people like my sister, good people who have conditions most of us pray we never have to deal with. My relationship with Natalie has made me the person I am today, a disability attorney who cares deeply about his clients well being. A disability attorney who treats his clients with the same respect he’d want his sister to be shown.

At my office, every client is treated like a member of our family. They are treated with dignity and respect no matter the challenges they and their families are dealing with. That is what makes us unique. And it’s why we hope you’ll consider us when you or someone you know needs social security disability (SSDI), supplemental security income (SSI) or private disability insurance.
