“We hired Idergy to perform an Arc Flash Hazard Assessment for two of our facilities. Claudia is professional and easy to work with. She was very thorough with gathering information for the assessment. The assessment includes a Coordination Study and suggestions for breaker settings. A list for placement of the Hazard Labels was included to make the application easier and more accurate. The end product is the most complete and accurate Arc Flash Hazard Assessments I have seen in my 23 years at Kinder Morgan. I feel that working at these facilities can be a safer environment now that we know what the electrical hazards are and what we need to do to mitigate the hazard or protect ourselves from the hazards.
Claudia, it was great working with you. I will recommend Idergy to anyone needing Electrical Engineering services. Thank you for being thorough and professional.”

"I’ve had the pleasure of working closely with Claudia over the past year, and I can confidently say she is one of the most talented and dedicated Electrical Engineers I’ve ever worked with. Her expertise in power system studies has been a game-changer for our team. Claudia doesn’t just run the numbers—she digs deep into the data, asks the right questions, and delivers insights that are both accurate and actionable. What really sets Claudia apart is the level of detail and thoughtfulness she puts into her work. Her reports are always thorough, well-organized, and easy to follow. She has an incredible ability to break down complex concepts and present them in a way that makes sense to everyone, from engineers to project managers. It’s a skill that not everyone has, and it’s one of the many reasons her work is so highly valued. Beyond her technical skills, Claudia is an absolute pleasure to work with. She’s collaborative, approachable, and always willing to lend a hand or share her knowledge.
Claudia is the kind of person you want on your team—someone who not only delivers exceptional results but also makes the entire team better in the process."

"Claudia is an intelligent and driven Electrical Engineer. Claudia and I worked together on Arc Flash and relay coordination jobs in West Texas a few years back. No one lines were provided on the job so Claudia sketched out the one lines. Claudia was very detailed and precise in her sketches and the relay data collected for the studies. Claudia produced top notch work. Claudia is easy to communicate with and listens to what you have to say. I would not hesitate to use Claudia on an electrical engineering job."

"I have worked with Claudia on numerous projects over the years and she has provided a very high level of service consistently by working to understand the needs and providing excellent solutions. She has always maintained strong professionalism which has been the reason we have continued to use her services. I would highly recommend her and her team."

"I've reviewed and performed 100's of arc flash studies in my career and Claudia's reports are some of the most detailed and useful documents I've ever reviewed. Clear, concise, straight to the point while still providing balanced recommendations for the site. I would recommend her company with no hesitation."

"Claudia is an expert in what she does! She communicates effectively and provides support to help the client understand the arc flash study results and implementation of safety systems to better safeguard employees and equipment."

"Claudia is detail oriented and professional in directing projects as well in working with her clients and employees."
