  • "We have been evaluating our stable of consultants -- which ones are leaders and which ones cause us to bang our heads against the wall. I hold MacKay and Somps as the gold standard. You do what you say you are going to do. You do it on time, you do it fast, and you do things that need to be done without me having to ask. When I do ask , it gets done right away. Communication is great and timely. Thank you for running a tight ship—we look forward to a continued relationship."

    Brian Cutting 
    Director of Land Acquisition, Woodside Homes of Northern California

  • "I have worked with the team at MacKay and Somps for over 25 years and have always found them to be direct, knowledgeable and fair. They are truly experts in the industry and are held in high regard by the local jurisdictions which is an invaluable asset when negotiating project approvals. Their commitment to customer service has always been outstanding and I have enjoyed a long term relationship with the entire team."

    David Ragland

  • "MacKay & Somps is our go-to engineering and planning firm.  We have been using them for over 20 years and consider them a vital part of our team.  We use them from the concept planning stage, to engineering and design, all the way through to the completion of our master-planned communities."

    Jeff Jones

    Rhodora N Biagtan
    Principal Engineer at Dublin San Ramon Services District

  • “I have a unique perspective on MacKay and Somps having built their plans when employed by a construction contractor (Teichert Construction), having managed their work as a homebuilder (KB Home), and having dealt with their completed projects as the Public Works Director for the City of Lathrop. In all capacities, I have found MacKay & Somps to be a reputable firm with excellent customer service, and an engineering staff comprised of competent and qualified engineering professionals.”
