Every case starts with a question
Most people who call us are asking one of two things. Whichever yours is, the first conversation is free and stays between us. Open any service to see what it involves.
How strong is your case?
For attorneys, families and individuals heading into court, whether the matter is criminal, civil, custody or corporate.
Investigative servicesAnswers you can stand behind.
Infidelity, hidden assets, custody concerns, a witness nobody can find. We uncover what's there and document it the way a detective would, with statements, affidavits and evidence built to survive cross-examination.- Infidelity, custody and hidden-asset investigations
- Witness location and background checks
- Identification of unknown assets
- Undercover operations
Litigation supportKnow your case better than the other side does.
We review the entire file, every piece of evidence, and tell you plainly where you're strong and where you're exposed. Then we do the legwork that changes outcomes.- Re-interviewing witnesses and canvassing scenes for new ones
- Background and asset checks to assess credibility
- Expert witness testimony when it's time to take the stand
SurveillanceEyes on the situation, always within the law.
Undercover, personal, vehicle and site surveillance, in person or online. Everything is gathered lawfully and recorded, so a judge can see it for themselves.More about surveillanceDifficult process serviceFor the people who don't want to be found.
Where a standard server knocks once and leaves, we keep going. We hold a 100% service record on difficult cases, and we can record service on video so no one can claim it never happened.More about difficult process service

From patrol officer to Chief of Police. Now on your side.
Vicki Yost started on patrol in Detroit and rose to Deputy Chief, commanding gang, vice and tactical units along the way. She went on to lead the Inkster Police Department as its Chief, and served as a policy expert with the Police Executive Research Forum.
She knows how investigations are built, how evidence gets challenged and what a judge needs to see. That's the difference between finding something and being able to use it. She started Shield Strategic Solutions to put that experience to work for people who need the truth, and need it to hold up.
