Client Testimonials

The attorneys are great! My fiancé is working with William on their Social Security case and the whole office has been so amazingly helpful. They helped us win the case and now are keeping us active to help with any paperwork or aftermath. Can’t recommend them anymore!

You live for the day you can retire but there’s one more bump to navigate, filing for your Social Security benefits. I started the process but was overwhelmed with the thought that I was not knowledgeable enough to answer all the questions to ensure my correct Social Security Disability Insurance benefits. I was luckily referred by a friend and couldn’t have been more fortunate :) The staff is brilliant; they were professional and courteous every time I called. Their team basically completed the SSA application process within months of signing and finally winning my SSDI benefits. If you’re trying to tackle this yourself, do yourself a favor and call them first. This firm is your answer to undertaking one of the biggest trials of your life. Good Luck and a Special Thanks to Arsi Nourouzi & Lori Decristo for all your time and effort you spent on my case and answering all my questions, you both are very special ♥ - Sincerely, RMS


I was fortunate to have been given a referral to Mr. Zimmerman and his exceptional team by a lawyer who had retained his services as well. She had only glowing things to say about her experience with this law office. She won her case after Mr. Zimmerman made an appeal on her behalf to Social Security Administration. As soon as I retained Mr. Zimmerman, I could discern I had chosen well. He and his exceptional paralegal assistant Arsi were experienced, knowledgable, compassionate, efficient, and demonstrated expertise in everything they did to help me get my benefits awarded timely to me. They went the extra yard to help me navigate the tangles I encountered at every turn in my dealings with Social Security Administration. I cannot say enough about all the help and support I received. If you need a great legal team, look no further than Pisegna & Zimmerman.

Excellent and professional firm. The legal assistant, Arsi, is diligent and responds immediately to any concerns regarding my accident case. Mr. Zimmerman is excellent as well. He represented me during a hearing and was informative throughout the process. I will be a life-long client at PISEGNA & ZIMMERMAN, LLC, as long as I live in the greater Los Angeles

Sami Amor

I had EXCELLENT results with Prisegna & Zimmerman LLC. A special shout out to Arsineh S. Nowrouzi, the Legal Assistant who was my focal point. I realize its a team effort but she was the person that kept me informed and on track of my responsibilities.. Great Job and Thanks Miss Nowrouzi! I was recommended by a close friend who also couldn't say enough about their work. Navigating thru the SSA is a daunting task. Almost impossible to do by yourself. With this team and working together you will be successful. Thanks Again

Garrett Covington

Mr. Zimmerman helped us with a Disabled Adult Child (DAC) claim. We contacted him on the first denial. He managed 1000's of pages over15 years of medical reports, and filed them in a manner that persuaded the judge to approve the claim. I found the firm very responsive to issues that came up during the long process, and am very grateful for the result.

Mariella Arriaga

I am more than pleased and grateful with the service William Zimmerman and the office provided. When I had my injury at work I felt very helpless, scared, and had no knowledge in what to do. I reached out to Myrna and she was amazing from the start. Special thanks to Julio who made this process easier, always professional, and always kept me updated.Julio went above and beyond, and an amazing support. Mr. Zimmerman was able to help me with a great settlement, and most importantly sent me to the best doctors to get the medical help I need. Everyone is very professional, and respectful. In less than a year they have made it possible for me to begin a new chapter in life. Thank you once again William Zimmerman, and the entire office, I would highly recommend their services to my family and friends.
