We're Here For Your Financial + Legal Recovery


When people are injured, most often they are unable to work and during these times, cash flow can become an enormous burden on the victim and their families. We recognize that our clients are suffering and are under enormous financial stress.

That is why we use the contingency fee arrangement. Under this arrangement, the client is not required to pay any fees or expenses unless the case is successful. If the client does not recover any monies from the lawsuit, there will be no legal fees.
