LaCroix Davis LLC

What LaCroix Davis LLC does

LaCroix Davis LLC is a privately-held Building and Environmental forensics and consulting firm headquartered in Granite Bay, California, with additional offices in Lafayette, California; Las Vegas, Nevada; and Carlisle, Pennsylvania. The firm provides forensic investigation, expert witness testimony, and consulting services to attorneys, insurance claims adjusters, construction firms, and government agencies on construction defect, construction accident, and environmental/industrial hygiene matters across commercial, residential, and industrial markets. Service delivery follows a senior-expert-led model: each engagement begins with direct consultation with a principal or senior associate who defines scope and prepares a case-specific proposal and budget for client approval.

The company's service portfolio is organized into three core lines. Building Forensic Services covers structural engineering, electrical engineering, roofing, drywall, concrete/foundation, HVAC, mold, and architectural defect investigations on construction defect and accident matters. Environmental Health Services encompasses industrial hygiene, occupational health, toxic tort litigation support, exposure assessments, and hazardous materials management for asbestos, lead-based paint, mold, silica, benzene, volatile organic compounds, and indoor air quality. Training Services delivers customized education programs ranging from one-hour lunch overviews to one-day seminars for commercial, industrial, and government clients. Supporting these lines are case-management processes covering assessment, investigation and analysis (with reporting options from concise summary letters to comprehensive computer-assisted reports including causality, recommendations, and cost estimates), and trial support (deposition and jury testimony). Underlying methodology combines on-the-job field experience with scientifically defensible investigation techniques, computer-assisted reporting, and visual and statistical tools designed for legal proceedings.

LaCroix Davis generates revenue through project-based professional services engagements with custom quotes per case; no standardized pricing is publicly disclosed. The go-to-market is enterprise field sales targeting legal, insurance, construction, and government buyers. The firm operates as an independent LLC with no disclosed institutional investors, parent company, acquisitions, partnerships, patents, mobile app, API, or social media presence beyond a corporate website. The senior team includes Principal James R. LaCroix (45+ years as a General Contractor specializing in building and construction defects) and Senior Associate Gordon M. Bizieff (31+ years in building and construction defects).
