Frost Law is Amazing! They helped me personally get ahold of my finances and get a fresh start. They were friendly and courteous, and patient enough to work with a financially illiterate 60 year old male. I would recommend them to anyone. If they can help me they can help anyone.

I got my questions answered in record time. Thanks so much!

When you are having an issue with the IRS, you need professional help to communicate with the right person within the IRS that can help you with your situation. Unfortunately I was not able to find that person and my situation continued to drag on for months. I would communicate by letter and also attempted to use the phone but to no avail. The IRS did not quit working my case and their letters indicated they were getting stronger in demands.

I found Frost Law Firm paid a reasonable retainer, and they were working my case within days. I was very impressed with their contacts within the IRS and how they represented me. Lauren Mata was my attorney and she was very diligent, great at follow up and did everything she said she would do.

My case was settled not long ago, to my benefit as we were able to prove that our position was correct. Whereas I did not have the credibility with the IRS, Frost and Lauren Mata did. I believe I received good value for what I was charged.
