— WHAT WE DO —

Investigative Services

Comprehensive investigative solutions tailored to legal professionals — from surveillance and asset searches to digital forensics and process service.

    Surveillance

    Surveillance is one of the most effective ways to obtain admissible evidence — and one of the hardest to do well. It takes patience, precision, and years of experience to get it right. With over 25 years in the field, we know how to deliver results without compromising your case.

    Asset Searches

    We help attorneys uncover what the other side doesn't want found — property, vehicles, business interests, bank accounts, and other financial holdings. Our asset investigations give you a clear, verified picture of what exists and where it's held.

    Locates / Skip Trace

    When someone doesn't want to be found, we find them. Using advanced databases, digital footprint analysis, and field-tested investigative techniques, we locate individuals for litigation, service of process, and background verification — including cases where other investigators have come up empty.

    Backgrounds

    From public records and criminal history to employment verification, education, and credit reports — our background investigations are thorough, legally compliant, and tailored to what your case actually requires. Whether it's pre-litigation due diligence or pre-employment screening, you get a complete picture.

    Social Media & Digital

    We dig into the digital side of your case — identifying social media profiles, documenting online activity, mapping connections, and capturing behavioral patterns across platforms. All findings are preserved with metadata and hash values, formatted for court submission and evidentiary use.

  • Icon of a shield with a gear and checkmark, and a circular arrow, representing security or system protection.

    Process Service

    When routine service attempts fail, we step in. We specialize in serving hard-to-locate and evasive individuals using creative, non-traditional methods that get the job done. Our success rate consistently exceeds industry standards — even on cases other servers have given up on.

    Trial Preparation

    We support legal teams through every phase of trial preparation — locating and interviewing witnesses, gathering and organizing evidence, and developing the investigative foundation your case needs to move forward.

    Bug Sweeps / Counter Surveillance

    Concerned about electronic surveillance? Our technical surveillance countermeasure (TSCM) services detect hidden cameras, audio recording devices, GPS trackers, and other eavesdropping technology. We sweep offices, homes, vehicles, and meeting spaces to ensure your conversations stay private.

— ABOUT US —

Meet Adam Winquist

Adam has been investigating since before he could drive — learning surveillance, report writing, and deductive reasoning alongside his parents in their Seattle PI firm. More than 25 years later, he's built Summit Investigations into a go-to resource for attorneys handling everything from corporate fraud and missing persons to complex domestic and custody matters. His work is thorough, ethical, and built to hold up in court.
