John Ogrodny
John Ogrodny is the founder and owner of Grey Owl Leak Detection LLC, a specialized diagnostic service based in Phoenix, Arizona, proudly serving the greater Phoenix metro area and surrounding communities. With over three decades of hands-on experience in engineering, construction, project management, and technical training, John delivers technical precision, quality-focused leadership, and genuine customer-first solutions.
Career Highlights
John graduated from Coronado High School in 1990 and worked summers at his grandfather’s Allen’s Plumbing in Scottsdale. He studied environmental engineering at Hawaii Loa College, became EPA-certified for asbestos, lead, and air quality projects, then apprenticed under solar pioneer Cully Judd. He co-founded Photonworks and later Building Energy Group, completing thousands of turnkey solar projects across commercial, government, and high-end residential work in Hawaii—including major installations for the Department of Defense, State of Hawaii, Johnson Controls, and the University of the Nations.
In 2017, John returned to Arizona. He learned leak detection from master plumber Patrick Jaeger (founder of Artisan Leak Detection, est. 2015), purchased the company in 2022, and rebranded it as Grey Owl Leak Detection. Since then, John has personally completed over 8,000 leak detections, with the company performing nearly double that volume.
We empower young minds to become problem-solving entrepreneurs and stewards of their communities and Arizona's water. Every leak we detect helps conserve this vital resource.
Grey Owl Leak Detection Today
Drawing on his proven apprenticeship model and family plumbing roots, John trained four recent high school graduates—Tyler, Ryan, Logan, and Gannon—into fully certified leak detection technicians. Apprentices assist on over 1,000 jobs, then complete more than 50 supervised pass/fail jobs with a senior tech standing by before certification to work for our plumbers. Procedures developed by John and master plumber Pat Jaeger are a major factor in our ability to consistently deliver fast, accurate, minimally invasive repairable diagnosis.
Entering our 5th year after rebranding, Grey Owl has maintained an impeccable 5-star review rating across all platforms. Whether you receive service from John or one of his certified leak technicians, you’ll get top-notch, professional service every time.
