    “It was a pleasure to work with Mehdi. We had a big project for him and he did it with such class and sincerity. He was personable, professional, thorough, thoughtful and makes every attempt to understand the clients needs and vision and delivers more. The project was delayed but mainly due to COVID related supply chain issues which could not be helped. The most important quality was he was very responsive and responsible. He performed with passion and was not easily pleased would not take mediocre result.
    Overall, We are very happy with him and his work ! We would strongly recommend him !”

    “Concept design group has designed and constructed a three bedroom two bath custom-made duplex in Fresno California.
    It turned out really nice and unique.
    Despite being a relatively young company, the expectation has been met and exceeded.
    I will definitely consider doing business with this company again.
    Some of the shortcom of the project were related to the City of Fresno extreme red tapes and requirements which caused a few months delays with unnecessary extra costs. I am sure if we were to do this again, we would approach it a bit differently and give it a much earlier start to finish time on certain items such as sewer system.
    This was my first project with concept design group that not only it was elegantly designed, they also managed the construction of this magnificently built duplex.
    Well done!!”

    “The absolute best and most meticulous architectural designer with the most spectacular vision and cost-effective ideas I’ve ever had. After meeting Mehdi, we were so excited to start working with him on the complete whole-house interior and exterior renovation, completely changing the style of the house to contemporary, and addition of our home, including new structural, plumbing, electrical, stucco, slab, AC, roof and all the finish work. He listened to what our main objectives were and came up with a design that far exceeded our expectations! Mehdi was always available for our many questions. He has created a beautiful home design that was far beyond what we could have imagined on our own. His attention to detail and his great vision for unique design have given our home design some very special unique touches! We love it.”
