From our clients!

First time doing business with La Marche / Hurtado.cc.
It was a pleasure to deal with a company that REALLY cares for customers, since nowadays for many companies Customer Service are words use for advertising purposes only. The technical support received was appropriate, and all interactions were handled in a timely manner. Thank you!!

I was introduced to David by a coworker who insisted I speak with him for a fuel project design. It has been the best advice given to me. David is a fountain of knowledge and is more than willing to help and provide service. He has been an invaluable source of information for me.

I am writing just to highlight the great service and support I have always received from David Hurtado. His support has always been there in a technically sound base and in prompt manner.

From a consultant point of view his work has been exceptional. Have a great day…

I was very impressed the first time I dealt with David. I was recommended to David’s company by our Cummins sales representative, and David helped me thru my first fuel delivery system project for a Florida Assisted Living Facility. He does not just send general cut sheets of systems, … but details such as pump HP values, cables sizes, fuel piping sizes, sensor requirements, etc. I would recommend him highly to anyone struggling with fuel system design.
