The team at Dersch Design & Engineering are key members of our solar system development team and a real joy to work with. Electrical engineering design and development is performed with depth and elegance when time permits or speed and improvisation when the crunch time comes.  The team has strong technical knowledge but even more important, a real world understanding of solving issues that affect the constructability and value of a design project in the real world. Their engineers care about doing a job right the first time and we feel fortunate to work with the Dersch Design and Engineering team.  I highly recommend Brian and his firm to others who care about having a constructible project delivered on time and on budget.

The continual rapid response and level of detail from Dersch Design & Engineering, Inc. has been an immeasurable asset to our business. They routinely have showcased their high level of comprehension for solar and electrical engineering. Their employees are always cheerful and professional and we would suffer a great loss if we didn't have them as part of our extended work family!

We hired Dersch Design & Engineering, Inc. to help us with a large, complex project. They were able to meet our specific desires and needs with their design and did so without inflating the budget. Their knowledge of electrical systems, green design principles, and great customer service were a tremendous help during construction.

The Dersch Design & Engineering team were a pleasure to work with on several challenging commercial solar projects. Under Brian’s leadership, his team has consistently delivered high quality engineering documents and construction phase design services. The Team’s "hands on" approach to coordination and delivery prove to be a great asset to our firm and to our clients.
