With almost four decades of experience in the plumbing trade, JP Strategies brings unmatched technical knowledge and real-world insight to every case. Founder John Petkovich began his plumbing career in 1987, inspired by his father’s belief that plumbing was a skill that could open doors anywhere. That foundation turned into a lifelong passion, a thriving trade career, and now, a trusted expert witness practice. Plumbing is more than pipes and fixtures—it’s a trade that touches every phase of a project, from underground systems to final trim work, across residential, commercial, and industrial environments. This breadth of experience allows JP Strategies to step into any dispute and deliver clear, informed, and defensible opinions that hold weight in courtrooms and negotiations.

Structural Engineering, Construction Defects - Codes, Civil Engineering, Steel, Masonry, Failure, Corrosion, Seismic, Wind, Collapse, Prestressed Concrete, Post-tensioned Concrete, Facade, Cladding, Leaking, Leakage, Decay, Wood, Structural Engineering, Timber, Concrete

As an engineer, I am fascinated by complexity and understanding new and different situations. I love to talk about engineering and explaining engineering processes and principles to young engineers and lay persons is personal passion. Examining a structural failure brings out my inner researcher, and explaining the cause and physics to a jury or arbitration panel channels my teacher personality. I work as a forensic engineer with the intent of helping the legal industry understand engineering principles and to help citizens resolve their disputes justly. I began professional practice at kpff in Portland, OR in 1998. In 2001, I was hired by DCI Engineers. In 2003, I started my own consulting engineering firm which I continue to operate. I have designed concrete, steel, masonry and wood structures, generally commercial, government or schools. About half of my work has been design of building facades or cladding systems. Seeking new challenges, I joined the faculty at the University o...
