Robert Ontko 

Over 30 years experience in providing assessments of damages to buildings and mobile units. Finding solutions by observing usage, determining cause of damage and paying meticulous attention to detail has been my career. I am well versed in insurance terms and policies of many states and would be available to speak with those operating in this field so that well informed decisions can be made by carriers.

This makes for a perfect match to team up with experts in the field of stone inspections both cosmetic and structural.
