Mike Rozenblum,

Slap Face Coffee & Tea

We were very happy to have selected M+R Engineering for our commercial project in Fremont.  Ramil and his team are professsionals and it was an absolute pleasure to work with them! They understood the challenges and specific requirements of what we were trying to achieve with Slap Face Coffee & Tea. Communication was very clear and they delivered results which passed city plan check review on the first round, without any time-consuming revisions. We would be delighted to work with them again in the future.

These guys are amazing!  Always on time and super helpful with all of our unusual requests for different jobs.  I highly recommend them!

David Orozco,

HPC Architects

I've had great success with MR Engineering Consultants, Inc. out of Fremont CA. Very responsive and competitive in fees.

Everyone in this office is by far the best I have worked with.

M+R is with no doubt, the best HVAC consultant company for our projects, and we are looking forward to many future successful projects together. 

They are prompt and easy to work with.  Competitive pricing with stellar service.  A true Design/Construction resource for all things MEP-related.

Very competitive, hardworking, generous and has a lot of satisfied customers.

We found working with M+R a great experience. They are a knowledgeable team of cross-discipline engineers providing professional and diligent services to realize our innovative architectural designs.
