Licensed New Hampshire Private Investigator
Private investigator services in Derry, New Hampshire
Kreymer Investigative provides surveillance, background checks, infidelity investigations, skip tracing, and insurance-fraud investigations for clients in Derry and throughout Rockingham County — backed by court-admissible evidence and a nationwide investigator network for cases that cross state lines.
Local coverage & context
Derry is one of Rockingham County's largest towns and home to the county's Family Division office, reached by Route 28 and I-93 (via Londonderry). Our investigators are familiar with the area around the MacGregor Park area, Broadway's downtown shops, and the Robert Frost Farm, and we run cases here regularly for clients who need boots-on-the-ground local knowledge, not a generic statewide template.
Derry's Family Division handles filings from across southern Rockingham County, which means custody and cohabitation cases from several surrounding towns often route through the same courthouse — useful context when you're gathering evidence that needs to hold up there.
