Client testimonials

We’ve started working with Frost Tax Law on our ERC claim that had stalled and was getting extremely frustrated with working with (or dealing with) the IRS. He was able to expedite a quick response as well as getting our claims approved and paid when I was barely able to get a response from the IRS. Highly recommend

Super kind and super helpful, they were patient with me all throughout knowing I was struggling to get by and never judged me for my past. Thank you frost law!!

Client testimonials

I found Frost Law Firm online after desperately searching for ways to expedite the long, painful process of getting desperately needed covid-19 pandemic era tax credits in 2024. Their legal team, including Hunter Scott, of this firm literally was one of my life-jackets on the fast-sinking ship of my business. Through their work with the IRS on my behalf, I had 90% of the tax credit refunds in hand by the close of 2025, which helped me turn things around. I highly recommend their expertise when it comes to the tax laws.

Allison W.

Very communicative and no use of "legaleze" to describe tax situations/complexities!

Keith M.

I contacted 6 law firms. Out of 6, I talked to 4 over the phone and 2 over email. Frost & associates, was the only one that listened closely, asked the appropriate questions during the consultation phase. Others were rushing, non attentive, and almost dismissive. Frost was the only one that made me felt heard and assured. After I decided to go with Frost, they were on top of everything, every single step of the way. Kept me in the loop, provided me with case updates regularly. They got my case dismissed before it even went to hearing.

Special Shout out to Nick Berger for doing an amazing job.

If I could, I would give them 10 stars out of 5.

Okan A

The entire team at Frost and Associates are so friendly and very professional. My Tax Attorney, Lauren Mata is one of the best. I have been so impressed with Laruen and her professional service that she has provided my firm. Thank you Lauren Mata!!

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.

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.

Advocate

Built on experience and honest counsel
