In today’s world, information is easier to access than ever—but accurate, reliable information? That’s a different story.
At Sigma Investigations, we conduct professional background investigations ranging from basic open-source research to comprehensive pre-employment and law enforcement-level screenings. Whether you’re hiring an employee, entering a business partnership, preparing for litigation, or simply seeking peace of mind, a properly conducted background investigation can help protect your interests before problems arise.
🔍 More Than a Quick Internet Search
Many people assume a background check is just typing a name into Google or running an online database search. In reality, professional background investigations go much deeper.
Depending on the client’s needs, investigations may include:
Criminal history research
Civil litigation history
Employment and education verification
Social media and online activity review
Neighborhood canvassing and field interviews
Reference checks and witness interviews
Identity and residency verification
Every case is different—and every investigation should be tailored accordingly.
💼 Pre-Employment & Professional Screening
Hiring the wrong employee can be costly. Businesses today face increasing concerns involving workplace violence, theft, fraud, and liability issues.
Sigma Investigations provides professional pre-employment background investigations designed to help employers make informed decisions with confidence. We also conduct specialized investigations compliant with California POST standards and other agency-specific requirements.
Our investigators understand how to identify inconsistencies, verify information, and document findings clearly and professionally.
⚖️ Investigations for Attorneys & Legal Matters
Background investigations are also valuable tools for attorneys and legal professionals. Whether preparing for civil litigation, locating witnesses, verifying identities, or evaluating credibility, accurate information matters.
Our team assists attorneys and firms with:
Litigation support investigations
Witness statements and interviews
Locate services and skip tracing
Asset and background research
👥 Personal & Family Matters
Not every background investigation is business-related. Sometimes people simply want peace of mind before making an important personal decision.
From online dating concerns to tenant screenings and child custody matters, professional background investigations can help individuals better understand who they’re dealing with.
At Sigma Investigations, our team brings decades of combined experience in law enforcement, military, government, and private investigations. We understand that background investigations require more than data—they require attention to detail, discretion, and professional judgment.
