We experienced some unfortunate graffiti vandalism of our welcome sign in Downtown Montpelier. Bob generously agreed to remove the graffiti. It turned out to be a difficult task due to the type of stone on which the graffiti was placed, but Bob was up for the challenge. He diligently did a test area before proceeding to the rest of the job, and was in frequent communication about his progress. He also applied a graffiti proofing coating layer to prevent future damage. Thank you, Bob!

Over the last ten years, I contracted with Bob for both large and small scale projects, and every project was always 100% complete, on time and thoroughly professional. Whether as a project manager or through direct conservation work, Bob became my go-to for tough projects requiring on-the-spot problem-solving in challenging environments. You will not regret contacting Arts Management Services.

I would like to give the highest of recommendations to anyone considering using Bob Hannum's many services. He did such a wonderful job cleaning, coating and removing graffiti from my "Whale Dance" sculpture, that I recommended him to the owners of many of my other pieces in various parts of the country. Over and over, I heard reports from my clients that echoed my own: "very professional; reasonable prices; work done in a timely fashion; etc." He even returned for touch-up work at no charge! And knowing he will be vigilant about keeping an eye on these pieces on a yearly basis takes a load off my mind.

I did not know I needed to have my bronze sculptures treated until I heard about Bob and his work. My sculptures look even more beautiful than when they were installed and I am so pleased they now are protected from the elements.

Bob Hannum repaired a large vessel that I have of Karen Karnes. It was in the garden and fell over making a long crack and chip. The vessel was woodfired so the surface has a very light rough texture with pockmarks and colors that are extremely subtle. The repair was so perfect that I cannot find where the damage was. The repair has also passed muster with a museum that is happy to receive it into their collection of American Crafts.

Your work on the ceramic pieces is amazing—I am very impressed and pleased!

Bob Hannum has worked on my sculpture and with my Studio for forty years. He has installed my work for museums in the US and abroad for my one-person exhibitions and major museum shows, and continues to do so. I and the institutions Bob works with have no question about his reliability to make certain my work is presented in the highest quality. He has my highest confidence and recommendation.
