Davis Associates

What Davis Associates does

Davis Associates, Inc. is a privately held, micro-scale consulting firm founded in 1970 and incorporated in 1987, headquartered in Newton, Massachusetts with 1-10 employees. The firm provides expert witness services and consulting testimony in litigations involving automatic pedestrian doors (sliding, swinging, folding, and revolving) and physics-related issues across the United States and Canada. Since 1993, principal Warren F. Davis, Ph.D. has served as expert witness in approximately 440 such cases, and the firm also performs medical malpractice consulting using signal analysis on clinical data such as ECG traces.

The company's core product offerings are a portfolio of standalone scientific software tools. RMFTL is a proprietary library of multidimensional Fast Fourier Transform routines that reduces complex multiplications and operates on external arrays without transposition. KAPMIER applies the Kaplan-Meier statistical method to patient outcome analysis, and KEYTAP implements keyboard-tapping functionality for neurological evaluation of patients. RDEC is a free Windows calculator that verifies compliance with the ANSI A156.27 revolving-door kinetic-energy standard, handling 2-, 3-, and 4-wing configurations. The firm also distributes a DIY Infrared Reflectometer design and a collection of educational physics resources (De Broglie wave mechanics animations, Pythagorean Theorem animated proof, gravitational radiation papers). The products are described as largely standalone offerings without a unified platform architecture, and RMFTL is still being ported from DOS to Windows.

The business model rests on two pillars: professional-services revenue from expert witness engagements (quote-based, no publicly disclosed fee schedule) and legacy software licensing for scientific tools (RMFTL, KAPMIER, KEYTAP), with RDEC distributed free of charge as a credibility-building tool. Customer segments are primarily legal firms and insurance companies requiring automatic-door expertise, with secondary exposure to scientific/research institutions and medical research users. The firm markets through a professional website, technical papers, free software distribution, and earned media coverage; it does not disclose revenue, has no outside funding, no parent company, and operates as a key-person-dependent solo practice.

Functional benefit

Products and services

• Expert Witness Services Expert witness services and testimony in litigations across the United States and Canada relating to automatic pedestrian doors (sliding, swinging, folding, and revolving) of all major manufacturers, plus physics-related issues and medical malpractice cases using signal-analysis techniques on clinical data such as ECG traces. Warren F. Davis, Ph.D. has served as expert witness in approximately 440 legal cases since 1993.
• RDEC (Revolving Door Energy Calculator) A free Windows program that calculates the kinetic energy of revolving doors to verify compliance with the ANSI A156.27 national standard, handling 2-wing, 3-wing, and 4-wing revolving door configurations with components including co-rotating ceilings, showcase floors, and control boxes. Includes User's Manual and FAQ.
• RMFTL (Row-oriented Multidimensional FFT Library) A proprietary library of real and complex power-of-two multidimensional Fast Fourier Transform routines that are faster and more accurate than iterative application of 1-dimensional transform routines, using significantly fewer complex multiplications (ratio approximately 2/D for D > 2) and requiring no transposition for large external arrays. Intended for scientific computing and signal analysis workloads.
• KAPMIER Software providing patient outcome analysis using the Kaplan-Meier statistical method for survival analysis, targeted at medical research applications.
• KEYTAP Software implementing a keyboard key tapping function for neurological evaluation of patients, used in clinical and research neurological assessments.

Direct peers

• J.S. Held: Technical and scientific consulting firm that provides expert-witness and litigation-support services across engineering, architecture, and forensic disciplines. Comparable in how it converts niche technical expertise into paid testimony and consulting engagements.
• Wiss, Janney, Elstner Associates: Engineering consultancy with deep practice in structural failure analysis, materials, and building-envelope forensics, regularly serving as expert in complex litigation. Comparable as an engineering-knowledge firm that monetizes expertise through expert testimony.
• Rimkus Consulting Group: Engineering and technical consulting firm whose expert-witness practice spans mechanical, electrical, and structural failures. Highly comparable because both monetize deep engineering expertise through expert testimony in product-liability and premises-liability litigation.
• Haag Engineering: Forensic engineering firm best known for construction and storm-damage expert work, with parallel expert-witness and standards-based consulting services. Comparable as a single-discipline technical authority whose founder-built reputation drives litigation engagements.
• Robson Forensic: Multi-discipline forensic and expert-witness firm offering engineering and scientific testimony in litigation. Most directly comparable peer — same business model of providing credentialed technical expert witnesses to legal clients, but with broader practice areas rather than a single niche.
• Engineering Systems Inc. (Sedgwick): Forensic engineering and failure-analysis consultancy whose experts routinely testify in product-liability and premises cases. Closely comparable to Davis Associates in translating physics and engineering analysis into expert-witness work for the legal market.
• ARCCA (Sedgwick): Expert-witness and forensic engineering firm with practices in biomechanics, accident reconstruction, and product failure. Same core business model of credentialed technical experts serving plaintiff and defense counsel.

Broad incumbents

• Exponent: Large science and engineering consulting firm with a substantial expert-witness and failure-analysis practice. Same revenue model at much greater scale and breadth; serves as the natural upper bound on what a Davis Associates-type niche expert-witness practice could become.
