    We have worked with Gary on numerous occasions over the past several years and one thing that immediately stands out for me is his passion for his work and his projects; even projects that may not have been his landscape designs.

    Gary Barnhart and GSB Design Group worked with me on the Windom Hill housing/residential project in Eire, Colorado.  I was the General Contractor's Project Manager and Gary was overseeing the design and construction for the landscape, including the streetscape and medians along CR 7 through the development.  Gary and his contractors performed quality work and demonstrated a willingness to give that extra effort to deliver a final product that was within budget, finished on schedule and truly enhanced the overall Windom Hill neighborhood.  Gary's integrity, strong work ethic and ability to act as a team player are unmatched in the industry.

    I write this letter of personal recommendation for Gary S. Barnhart.  I have had the great pleasure of being a client of Gary’s for many years and worked very closely with him on the Vista Ridge and Vista Pointe landscaping projects in Erie, Colorado. Besides being a joy to work with, Gary is a take-charge person who is able to research and implement the most cost effective and creative streetscape/landscape solutions while educating and communicating the benefits of those.  His knowledge of the industry has been invaluable, resulting in consistent cost savings which has been a direct result of his diligent and timely work. I highly recommend Gary, if alone based on his integrity and work ethic.  It has been my experience that he will exceed your needs. Lisa A. Jacoby, District Manager Special District Management Services, Inc.

  • Dave Rhodes

    Gary and I have worked together on several projects over the past 5+ years. He was responsible for planting material approvals, observation, plan and specification adherence for streetscapes and a 7 acre park including playground equipment, a small water park and gazebo in Erie Commons, in Erie Colorado. The complexity of design and the requirements of Erie made this a very challenging project. Gary kept notes that became invaluable after several supervisory changes by the subcontractor; which made my job much easier. He also assisted with signage and streetscapes at our Wyndham project in Frederick, CO; there assisting in design adherence on monument signage. I found Gary always to be professional yet willing to show flexibility and able to think on his feet. I can wholeheartedly recommend Gary Barnhart as a Landscape Architect and a professional.
