    “It has been a great experience working with Dan on my projects! Dan is knowledgeable and proficient as an engineer, he is a good team player which helps a lot while working on projects. He is very honest and transparent, he has always kept me informed about the progress and about the time he has spent on my projects. He is good at working with the city officials and complying with the code requirements. His communications and responses are quick so I have never had to worry about completing our projects on time. I highly recommend him to anyone who needs a good engineer for their project.” Shaffy N.
    "Dan at DRP did an amazing job with my plans for new construction of a small modern house in the Joshua Tree area. I brought him what was basically a concept floor plan and he turned it into a set of permitted plans. The grading plan, mechanical layout, structural engineering and everything else needed to obtain the building permits was handled smoothly through DRP. Dan was 100% responsive and quick with turning around any comments. His prices are as fair as anyone I have found. I would use him again without hesitation." Josh C
