Why a specialized tax lawyer
IRS personnel resolve cases favorably when they worry about losing in court. Specialized tax training plus litigation experience raises that hazard for the government.
A CPA who prepared the return, especially under Circular 230 pressure, often cannot finish an aggressive audit or collection fight. That is when a tax litigator is needed. Read the resume for education, experience, reported cases, and bar memberships.
I say that as an attorney myself. Cliff did a superb job on my tax dispute. Not only did he address the relevant issue with the IRS in an extremely creative and persuasive way, he explained his approach and strategy to me in a manner that made it readily understandable.

What to expect when you call
When you call Clifford Ribner's office, most likely you'll reach a receptionist first. If Mr. Ribner is available he'll take your call and simply explain his credentials and the types of cases that he takes, and how you can retain him. Mr. Ribner has over 47 years of legal experience and you will not find anyone more qualified.
The best part is that you're not speaking to a salesperson that pretends to listen to your story just to sign you up for a case that some junior attorney will have on their desk. You're speaking to an actual attorney. For this reason, Mr. Ribner cannot give you legal advice until after you have retained him, and he cannot listen to the details of your case.
Most "free consultations" you hear about are not from experienced attorneys; they are from legal-case-farms that put an experienced salesperson to close you under the disguise of free advice.
You are welcome to call these high-pressure salespeople first. When you're dealing with an "impossible" tax problem, and you're ready to hire someone who has a track record spanning decades, then please call Mr. Ribner's office at 918-582-9200.
