About Us

BLI Investigations, Inc. (BLI) was started in 1990 by Jeffery Brose after a rewarding career in the Portland Police Bureau. He was twice commended for valor while with the PPB. One medal of valor came from Oregon Governor Victor Atiyeh, a very rare occurrence to this date. When he left the PPB for private work he was one of the most commended officers in the history of the bureau. Investigator Jeffery Brose continues to actively conduct surveillance and is deeply involved in all assigned cases.

In January 2006, Investigator Stephanie Wintermantel was promoted to Corporate Secretary upon the retirement of Investigator Michael Lindsey and continues to work closely with her father and Corporate President Jeffery Brose. Stephanie presently holds the position of Corporate Vice-President. In addition to her corporate responsibilities, Stephanie continues to be an invaluable member of the BLI team directing many operations as a full time licensed private investigator.

In 2012 the corporate name and structure changed to more accurately reflect the current makeup of the business. The past and present forms of BLI were created on a principle that makes it unique and is one reason BLI continues to be used by state and government agencies, insurance companies, law firms and corporations for decades. That one principle is INTEGRITY. BLI continues to work with a small, tight nit group of licensed professionals doing surveillance work that is unmatched in the region. Both Jeff and Stephanie have resisted expanding the business so they can continue to give a hands on personal touch that has separated BLI from all of the other firms in the region.

The surveillance investigations the BLI team perform saves millions of dollars each year for our clients. BLI is the longest running surveillance only private investigation business in the State of Oregon.
