Good Morning, It's always great to see Dwayne Bell from Guardian Fire Protection when he stops by to help with our Fire Sprinkler System. He really has the experience and it shows when the job is finished, always perfect. Before the project begins he respectfully takes time to go over the plan with us and afterwards provides a professional detailed explanation of the procedure. I consider him to be one of the best in the fire protection industry so please take the time to recognize him on our behalf. Thank You, Francis Duve (Frank) Director of Engineering Gaithersburg Marriott Hotel
