About Us

OST consultants learn what our clients do and dive into the details. Unlike consultants who stay on the surface merely “managing the process,” our consultants take ownership of the content to help develop the best solution possible for a specific proposal.

Winning Federal Government contracts requires precise responses to complicated technical requirements through compelling and compliant narrative and pricing. Mistakes are unforgiving. They could potentially disqualify the entire bid, costing jobs and impacting entire companies’ livelihoods. Our consultants don’t just triple-check. They quadruple-check everything because they understand and care about the impacts.

Government Contractors are continuously seeking a competitive edge. They engage OST’s consultants, trusting us with their most important pursuits. Our consultants are both teachers and students of the Government business development profession. It’s easy to fall behind and think in terms of “yesterday” when trying to solve today’s problems. Our consultants are constantly reading, attending webinars and conferences, taking Bid & Proposal Academy and other classes, and shadowing other experienced colleagues to learn and provide more value for our clients.

Winning proposals is a team sport. It requires dedication, long hours, and sometimes pushing past the point of exhaustion to get outstanding work done before the deadline. OST’s consultants carry the load together, stepping up when our colleagues on the client or consultant side may need help. We take responsibility and work proactively to fix what needs fixing, even if it’s not in our job description.

Competing and winning at the highest levels of competition in Government contracting is mentally and physically tough. OST consultants are dedicated to helping our clients succeed. We operate in high-stress environments, respond to challenging Government requirements, and sometimes work 12-hour days 7 days a week. OST is in the business of winning proposals instead of merely completing them.
