Jillian was able to reign in 22 years of emotion to achieve our legal goal with a quick result that was only delayed by opposing counsel's negligence. Jillian is a great listener that can tune out the static to achieve results without costing a fortune. So grateful to close this chapter with a great result. Way to go Jillian Allen!"
