What Lange Technical Services does

Lange Technical Services, Ltd is a privately held forensic automotive engineering firm founded circa 1990 by Carl and Jeff Lange, initially operating out of their Uniondale, New York home. The company specializes in forensic investigation and analysis of motor vehicles for legal, insurance, and law enforcement purposes. Its service portfolio covers six core areas: Vehicle Fire Origin and Cause Determination, Accident Reconstruction and Collision Damage Analysis, Electronic Systems and EDR Data Collection, Mechanical and Electrical Malfunction Investigation, Stolen and Recovered Vehicle Investigation, and Forensic Automotive Engineering. Customers include insurance companies (claims adjudication and fraud detection), attorneys and legal professionals (litigation support and expert witness testimony), law enforcement agencies and district attorneys (criminal investigation support), and private individuals. The firm maintains a single headquarters in Deer Park, New York (751 Long Island Avenue) and dispatches certified technicians nationwide across the United States.

The firm's investigative technology stack comprises FARO 3D scanning for accident reconstruction, drone-based aerial imaging for scene mapping, Bosch Crash Data Retrieval (CDR) for Event Data Recorder data, the Berla iVe system for infotainment and telematics data, Autel diagnostics for vehicle system analysis, and Toyota Vehicle Control History for operational data. The technical team is led by Jeff Lange, PE, a licensed Professional Engineer in New York State, Board Certified Forensic Engineer, and ASE Master Automotive Repair Technician, who personally oversees engineering review at all investigative levels. The firm has pioneered forensic locksmithing with published laboratory and microscopic analysis protocols for vehicle locking systems.

Lange Technical Services generates revenue through professional service fees billed on a per-case basis. Customers initiate engagement via dedicated service request forms on the company website (insurance/customer request form and attorney request form). Pricing is not publicly disclosed; engagements are quote-based. Revenue model is exclusively professional services, with no subscription, product, or licensing components. The firm is family-owned with no disclosed external investors, private equity, or institutional ownership. Operations are sustained by reputation-driven inbound demand rather than active marketing campaigns, and the firm's investigative findings have been consistently upheld in court proceedings across the country.
