“I was in a car accident.  The insurance company was cancelling my physio, even though I still had months of work ahead.  I saw a road side sign saying “Ever tried to argue with a woman?”.  So I called Sullivan Law.  Siona and Madina took my case, giving me great advice, and dealt with the insurance company directly.  My rehabilitation was able to continue until i regained my mobility.”
