Division of Administration

"Customer-Focused and Service-Oriented"

Sean Strate, Chief

The Division of Administration (DA) develops OSMRE’s administrative policies and procedures and implements the Bureau’s administrative support activities in the following program areas:

  • Acquisition and Procurement;
  • Property and Fleet Vehicles;
  • Leased Space;
  • Continuity of Operations Planning;
  • Safety and Occupational Health;
  • OSMRE Directives;
  • General Services Budget Accounts;
  • Printing and Publications; and
  • FAIR Act (Competitive Sourcing)


Recognizing that we are a customer-focused and service-oriented organization, we strive to provide personal and exceptional customer service. Tenets of our customer service philosophy include: respect; maximizing personal interaction; communicating with confidence and assertion; appreciating the customer’s constraints; respecting the customer’s time; and soliciting and receiving feedback in an environment of continuous learning and improvement. Division of Administration employees are empowered to make decisions.

Communicating to Achieve Success

The best possible customer service is delivered when we share a mutual understanding of each other’s expectations, capabilities, and objectives. We understand that you have qualifying expectations about the services you require (time, location, quantity, cost, etc.). We will always strive to meet your needs—within statutory and regulatory limits—either through implementing simple solutions or through constructing and presenting more complex options for your consideration. Our goal is to ensure that you know what you can expect from us and what, in-turn, we need from you to ensure the best possible outcomes are achieved.

I invite you to contact any of our subject matter experts to assist you. I also encourage you to provide feedback on your experience with the Division of Administration by contacting me at
