Exclusive practice in tax resolution for the past 17 years. [Prior to that, I practiced in the private and public sectors doing both litigation and transactional law.]

I enjoy helping both businesses and individuals in resolving their tax problems and educate clients from the beginning of their cases on how not to owe taxes again. Resolutions have included offers in compromise, installment agreements, penalties abatements, release of wage and bank levies, release, withdrawal or subordination of liens, and innocent spouse petitions. I have also successfully represented clients in numerous audits and appeals.

Client Reviews

For some unknown reason, I neglected to file my income taxes for several years. With that, I ended up getting notices from the IRS. I had no knowledge on how to deal with the IRS, so I contacted Enterprise Consultants Group as recommended by a colleague of mine. The firm’s tax attorneys helped me get a good deal. My funds are back. Thanks, Enterprise Consultants Group.

Before we started working with Enterprise Consultants Group, our company owed $100,000 in past taxes. But the tax attorneys at the Enterprise Consultants Group dealt with the IRS on our behalf. Because of that, we settled our debt for $10,000. The total cost we paid to our tax attorneys was less than the original due. Thank you Enterprise Consultants Group for alleviating our heavy burden


Enterprise Consultants Group has outstanding attorneys. They kept me informed promptly. They we’re not in a hurry to settle our case just to get their fees. They did what they could to get me the best settlement I deserved. I would recommend them to any person who needs help with his tax problems.


My business received letters from the IRS indicating that they had opened and audit. In know I needed help but I was reluctant. I Google searched and found Enterprise Consultants Group, then called for a free consultation. I was impressed with professionalism knowledge of the consultant that I spoke to so I hired them for my business. During the audit period they were always available to answer my questions. I feel that they handled things efficiently and I'm very happy with the end result.

After my divorce I was left with a heavy tax debt of over $250,000. To make matters worse I was broke and feared that my wages were going to get garnished. I called Enterprise Consultants Group after seeing a TV ad and they quickly got work with resolving my issue. They settled my tax debt for $3500. I quickly borrowed that amount from family and paid it off. Now that I'm tax debt free, my stress level has come down and I'm doing much better with my finances.

The Advocates at ECG helped me clean up a huge mess that another tax firm created. They honestly exceeded my expectations. Now ECG continues to file my taxes every year. I am thankful to have found a firm that I can trust with my taxes.
