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.
