Profile

Profile

The Aquatic Accidents group specializes in water accident reconstruction, forensic investigation, expert witness services and case consultation.  

A Ph.D. in coastal sciences is necessary to fully understand and interpret accidents in the ocean and other moving water bodies.  Drs. Stephen P. and Stephen B. Leatherman have practical and scientific background and expertise to determine causal elements and recommend corrective action to improve water safety and minimize litigation exposure. 

Their depth of knowledge in physical processes,  the scientific method and breadth of experience make them the expert witnesses of choice to appear before courts and regulatory agencies.   Other members of the group have public swimming pool management experience.
