Do not look anywhere else, they had my nightmare of vehicle bought back in no time! They also assisted my mother with her lemon.
Barry and his office took care of our Lemon Law case with Subaru. They handled it professionally and responded to our calls and requests with great patience and promptly. I'll use their office again if I need to, and I cannot recommend them enough.
I purchased a used vehicle for my son and after the sale, learned that the vehicle was under a serious recall and shouldn't be driven. The dealership refused to take it back. I contacted several lemon law and dealership fraud attorneys, only to be turned away. The case was difficult and was told they couldn't help. I then contacted Barry Edzant in Valencia who took my case. Within two or three months, Barry had gotten me all of my money back on the car, plus some, and it was out of my life. Barry was professional, competent, and efficient. I'm happy to recommend him to my clients as well as my colleagues.
Barry is a true professional. When it comes to personal injury and lemon law cases, he is a master. He has a ton of experience in his field. If you are looking for someone who advocate for you and get what is fair he is definitely your guy.
Barry and his staff did a fantastic job with my case. I highly recommend Barry to handle your case, I would not hesitate to use his firm again if needed. Barry and his staff are true professionals that take the time to walk you through all aspects of the case from start to finish.
I would recommend Barry and his team to all my friends and family. Him and his team did an amazing job and he is truly a professional at what he does. He takes his time to listen to you and to answer any questions you may have. He gets back to you within a reasonable time when contacting him.
I called a few Lawyers about my Lemon. Barry was the only lawyer to actually take my call personally and spend the time with me to make sure I understood everything. I am so grateful for him and for Clare. They worked so hard and fast to get me everything I wanted! They were never impatient with me (and I called a lot!). Thank you both so much!
Called him in need ... he went above and beyond in listening to me and providing me with clear information... I'm grateful I called him and will most definitely use him services with my case and will refer others I know to him. I wish all lawyers were as helpful as him.
There is nobody better than Barry for a lemon law case. Our van kept on stalling, and the dealer couldn't figure out what was wrong with it. I turned to Barry to see if there was anything that could be done, and he got us a fantastic result. He was open and honest about everything that we could expect, he always returned phone calls and emails, and he made the whole process very easy for us. I would happily recommend Barry to anyone who thinks they might have a lemon.
