I was involved in a case which took five years to settle. Fillmore Spencer was there every step of the way and was as helpful as possible. When we encountered problems, they resolved them as quickly as possible. I was always informed immediately of any developments in my case and had any and all options clearly explained to me. And given what a difficult client I know I am, I can honestly say they know how to handle difficult clients with expert gloves:)! While my lawsuit was miserable, these guys made the experience more tolerable. They are officially my legal team now!!!
