Client feedback
What our clients say.
Long-term partnerships built on trust, collaboration and results.
My office has been involved with affordable housing for the past 17 years. We have used Khalifeh Associates on many of our projects. They have been an MEP engineering firm that has provided excellent service from my point of view.
Jack Khalifeh and his team were dedicated and thorough in their design of the new AC system, and were consistently involved thereafter in the post-upgrade quality control testing to ensure that the system was operating properly.
We have high praise for their work ethic, work product and can confidently recommend Khalifeh & Associates, Inc. as a solid and reliable engineering firm. Khalifeh & Associates are experts in their field.
