  • Christopher J. Moore

    Tim and I worked together on a gift tax valuation controversy. Tim was instrumental in helping my client reach an acceptable compromise with the IRS. I will call Tim again when the need arises.

  • Stephen Dillon Hartman

    I can gladly endorse Tim for his skills in both civil and criminal tax matters. We worked together on a matter, and his knowledge makes him invaluable. I've even sought his advice a couple of times since we worked together. He is always helpful and responsive. If I found myself in a tax investigation, there isn't anyone else I would hire.
