  • Park & Longstreet, P.C., law firm group is very easy to work with, they are dedicated to helping. There are no upfront fees or charges. I did not pay attorney fees for services unless they obtain a reduction in my property's assessment.

  • The Park & Longstreet firm has, for years now, effectively helped me in regard to appeals of my property taxes, and has not only saved me thousands of dollars, compared to tax years without their intervention, but even recently shocked and surprised me with a $1016.73 refund from the IL Property Tax Appeal Board for a prior year, based upon their skilled protestations on my behalf! Thank you very much, Park & Longstreet! Your competence is showing, and I can certainly use the money . . .

  • We have been happy with your work on our behalf in the past and we look forward to continuing to work with you in the future.

  • We have been very happy with your services for both our primary house and our secondary house. You have reduced our primary house taxes three times and our secondary house taxes twice. And to top it all, you have appealed some other taxes for our secondary house (which I was not even aware of) and you got me a net refund of about $1,000.
