Client Testimonials

“I just wanted to thank you for your clear and very helpful explanation of the seriousness of the
electrical defects for Mr. And Mrs. Winslow today. That was exactly what I had hoped for, giving them
a clear description of the issues, coupled with some sense of the risks involved – difficult as they may be
to quantify.”

David W esq.

“Mr. Perry, you did great job for our team, I can see that this is not your first Rodeo! I’ve got another one
I want you to investigate in Petaluma.”

Hal C. Esq.

“Mr. Perry handled an extremely complex products defect case for us involving technical concepts and
devices. He identified the key liability issue, which only a person with real life experience would have
seen. His analysis was the key to our successful resolution of the case. He was always responsive and easy to work with. He’s the go-to guy for electrical engineering and contracting issues.”

Kevin O. Esq.

“I am an independent legal consultant/expert with over 30 years’ experience specializing in
electrical cases involving construction, explosions, arc flashes, vehicle fires and airline incidents to
mention a few areas. I recently had the pleasure of working with Mr. Perry, an electrical engineer from
California on an electrical arc flash incident. I found Mr. Perry to be very detail orientated when it came
to analyze the evidence and facts of the case. Of most importance he was insistent on having all the
evidence prior to making any conclusions or giving any opinions. He is extremely knowledgeable in the
areas of the National Electrical Code, NFPA 70E and OSHA regulations. Mr. Perry’s hands on experience
in the electrical construction field was very helpful in determining and verifying the status of the
electrical systems code compliance. He is very willing to work as a team and consider all possibilities and scenarios. I would highly recommend Mr. Perry as an expert electrical engineer for cases involving a wide range of electrical issues. I am personally looking forward to working with him again soon.”

“Joe did an excellent job analyzing the costs of replacing exterior transformers used by a metal finishing company, including the costs associated with engineering and installation. His consultation provided us with critical information that shaped our defense to the alleged costs of replacing the external transformers.”

Hakop S. Esq.

“Joe came in on short notice for my case which involved a power outage and negligent utility
inspections.  He made a presentation at mediation regarding the use of infrared inspections and
underground inspections and how the defendant should have been aware of the issue that caused the loss.  His work helped get us a good result for the client.  He was very professional and easy to work with.”

responding to opposing expert witness contentions. We would certainly consult with Mr. Perry again in
connection with construction defect cases involving electrical issues.”
