Bradley H.

I can't say enough about Heather Posey's expertise and dedication. She is knowledgably thorough, and incredibly responsive. Whether its ERC audit, a Maryland tax issue, or a complicated IRS matter. Heather delivers outstanding results. Highly recommend her to anyone needing a top-tier tax attorney.

Rebekah C.

My case resolved with the top 1% of possible outcomes. Just an entirely ridiculous success. I don't have the expertise to know if it was good lawyering per se but I definitely can't rule it out, and the best argument in just about any situation is simply pointing at the scoreboard for how well things worked out. Which is this case was amazingly well.

Matt E.

I had an excellent experience working with Frost Law, especially with Heather Posey. She expertly handled my complex tax situation with exceptional thoroughness, deep expertise, and unwavering professionalism. Heather went above and beyond to make sure I felt supported throughout the entire process, demonstrating true empathy for my concerns. I was impressed by how efficiently she completed my case in a very timely manner. I highly recommend Heather Posey and the entire Frost Law team to anyone seeking knowledgeable, compassionate, and effective assistance with tax issues.
