See What Sivan's Clients Are Saying

I contacted Sivan because my insurance company denied benefits to my paraplegic son. Prior to contacting Sivan, I had reached out to several other law firms. I was thrilled when Sivan agreed to handle our case. The entire team went above and beyond to fight the insurance company. I would recommend the firm to anyone in need of a disability lawyer to resolve an insurance issue.

I was forced to sue my insurance company based on the denial of a claim and I was referred to Sivan Tumarkin. During the whole process he gave me comfort in knowing I was in good hands. Not only did he win the case, it was fast and I was extremely happy with the settlement.

Sivan’s wealth of knowledge, strong morals and kind nature gave me a much needed sense of hope! He is outstanding in his field and in just over a year got my insurance company to overturn their decision to deny my LTD claim. Thank you all for your efforts, giving me the means to pay for uncovered treatments necessary for my recovery.
