David A. Doddridge
Mr. Doddridge is a building and construction professional with over 30 years of hands-on experience in the construction and building inspection industries. Mr. Doddridge has testified in numerous trials and depositions for both plaintiff and defense attorneys. He has been qualified as an expert in construction and personal injury cases in courtrooms from New York City to Connecticut to Boston and has authored and presented numerous Continuing Legal Education courses, coast to coast.
David has been specifically trained in residential and commercial building codes, construction site safety, residential and commercial building envelopes, slip, trip and fall accidents and building inspections. His decades of practical experience provides him with the unique ability to translate written code words into three-dimensional, real world interpretations making him extremely valuable as a forensic expert.
Since the late 1970’s, Mr. Doddridge has been involved in the residential and commercial construction and building inspection industries. He also has extensive experience in prefabricated buildings and ran separate building manufacturing, roofing and drywall companies as subsidiaries of his construction company.
When David was only two years old, his mother painted a picture of him “helping” his father perform construction work by hammering a nail into a scrap piece of lumber. As this painting depicts, David has building and construction in his blood and he has never chosen a profession other than that related directly to the building and construction industries.
Using the partnership and knowledge of his father, combined with his natural instincts and abilities as a building professional and various college-level certifications as his primary education, David has worked side by side with his dad in the family building inspection and construction businesses since the late 1970’s. As Mr. Doddridge says, “you cannot learn in college what you can learn from your father”. With that as his mantra, David is a firm believer that there is no better educational resource than hands-on experience.
In 2014 Mr. Doddridge was hired as the lead expert by one of New York City’s most prominent personal injury law firms to act as the plaintiff’s safety expert in a construction accident case that returned a verdict in favor of the plaintiff in the amount of $62 million, the highest amount ever awarded to a single plaintiff in the history of Queens, New York.

He has experience in state-of-the-art design and manufacturing, in both production and research and development environments. He has also performed forensic and failure analysis investigations of material and product failures as well as structural engineering analysis. As Engineering Manager, he was responsible for safety reviews and signoffs of all newly shipped products, and he has directly supervised mechanical, electrical and software engineers.
Mr. Popp holds a Masters of Science Degree in Administrative Studies from Boston College, a Bachelor of Science Degree in Mechanical Engineering from the University of Massachusetts and a Certificate in Engineering Management Development from Worcester Polytechnic Institute, and has completed PhD level course work in Bio-Mechanical engineering as well as Masters Level Coursework, CAD, Thermodynamics, Numerical Analysis from Northeastern University.

Mr. Graham is a seasoned construction professional who ‘came up through the ranks,’ beginning by ‘working the tools’ in his father’s woodworking shop. His years of field work experience includes private, commercial, and public construction projects, carpentry, millwork, cabinetry, and mechanical/electrical/plumbing coordination.
Mr. Graham’s decades of administrative experience includes Senior Scheduler, Chief Estimator, Senior Project Manager, and Director of Operations. While he ‘cut his teeth’ in the high-end custom residential and commercial construction industry in New York, he attended night school to work towards his Bachelor of Arts Degree in British Literature, from Hunter College, New York (1991).
In 2006 McGraw-Hill Technical Book Group published his book “Managing Residential Construction: Strategies and Solutions.” Derek has also acted as a construction defect expert witness within the construction industry on numerous defect and delay civil litigation matters.
