“We develop tailored compliance programs to meet the needs of each individual client.”


Lori counsels government contractors in all aspects of contracting with the federal government.  She has extensive experience with the review and interpretation of solicitations, bid and proposal preparation, and the drafting and negotiation of prime contracts, subcontracts, joint venture agreements and teaming agreements. She routinely counsels large and small businesses on the federal government’s small business and mentor-protégé programs. She also provides advice on government contract compliance requirements, assists in constructing and implementing mandatory compliance programs, provides ethics training, and performs compliance audits.

Lori has successfully litigated numerous bid protests before the Government Accountability Office and the Court of Federal Claims, including multi-million dollar bid protests involving information technology procurements and OMB Circular A-76 competitions. The types of protest issues have included: best value determinations, including price-technical tradeoff decisions; past performance evaluations; cost and price realism analyses; application of evaluation factors; compliance with solicitation requirements and responsiveness of proposals; meaningful discussions and clarifications; and challenges to solicitation terms and conditions. Lori also has been involved in size protests before the Small Business Administration.
