About me

I help U.S. government contractors win contracts that they have been unfairly denied and deal with their troubled contracts.

Based on my experience in government and corporate positions as well as private practice, I focus on federal contracting issues, U. S. Government regulation of international business, as well as a wide range of transactional and litigation matters.


For a short primer on federal bid protests, contact me by email.

  • Michael Charles Doland

    I was more than impressed by a recent answer of Mr. Van Horne. Not only was it accurate (with citations to the relevant statutes) but analytic and customized to the needs of the Avvo asker. These are exactly the qualities that every client would look for when hiring an attorney.
