About Us

Mama Bear PI knows that contacting an investigator for help can be daunting, especially when your questions involve loved ones.  We understand how difficult it can be to discuss a cheating partner, a wayward child, an abused elder, or simply a need to screen a prospective romantic interest.  Since starting Siedow & Associates in 1992, we’ve seen, heard and investigated just about everything.  We’re easy to talk to, and understand what you’re going through.

While nothing much surprises us, each case is unique, and is handled as such. We pull together a custom team from our global network of legal and investigative specialists to meet the specific needs of each client and case.  We consult with you to determine the most effective, efficient, cost effective method of accomplishing your goals.  We’re capable of handling everything from financial and domestic investigations to fraud and identity theft.  Team members can include attorneys, asset locators, financial analysts, computer, phone and internet investigators, expert witnesses, industry specialists, surveillance and undercover operatives and more – whatever it takes to get the job done effectively and with the maximum possible return.

Whatever you need, wherever you need it, we’ll get it done with your best interests in mind.
