Client testimonials

We tried everything before hiring an attorney to deal with the IRS. They were able to get the IRS to correct their own mistake. I hope I never need them again but if I do at least I know where to go next time.

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.

Michael U.

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.

Janet V.

Precision

Every detail matters in litigation

The difference between winning and losing often comes down to what you noticed that others missed. I don't overlook anything.

Clarity

You need to understand your options

Legal jargon clouds judgment. I explain your situation plainly so you can make decisions with full knowledge of what's at stake.

Specialties

Six practice areas, one standard

The law doesn't fit neatly into boxes, but the problems people face do. I've spent years learning what works in each arena.

Criminal

Defense when the stakes run highest

The first hours after arrest determine everything. I know how to protect your rights when it matters most.

Family

Custody and divorce require clear thinking

Family law isn't about winning. It's about protecting what matters most to you and your children.

Business

Contracts and disputes demand precision

Most business problems start with unclear agreements. I help prevent them before they become costly litigation.

Appeals

Winning on appeal requires different strategy

Appeals aren't about retrying your case. They're about finding what was missed and making it matter.

Employment

Your rights at work deserve aggressive defense

Employers count on you not knowing your rights. I make sure you do and that they're protected.

White collar

Complex cases need someone who understands

Federal charges and financial crimes require specialized knowledge. I know how to navigate the details that prosecutors rely on.

Writing

Thoughts on the law

Practical insight for your case and situation

Arrest and your constitutional rights

What happens in those first critical hours

Protecting custody when relationships end

Your children deserve a parent who planned ahead

Why contracts fail and how to prevent it

The agreement you ignore today becomes tomorrow's lawsuit

Federal charges demand specialized defense

Complex cases require someone who knows the system

Standing up for your rights in the workplace

Employers count on you not knowing what you're owed

How to win when the first trial didn't

Appeals are about finding what was overlooked before

Foundation

Decades of courtroom work shaped my approach

I've seen what wins cases and what doesn't. The difference lies in preparation, clarity, and the willingness to challenge every assumption. Your case deserves someone who knows the weight of these decisions.

Strategy that works

Every case demands a fresh look and a willingness to question everything.

Results matter most

What you need is someone who knows how to win and won't settle for less.

Direct and honest

No promises you can't keep, no strategies that don't serve your interests.
