The Conservation Solutions Team

Our team includes a broad and talented group of Conservators, Technicians and Administrators to organize, perform and oversee the amazing range of projects we engage in. Our Senior Conservators are Fellows, and our Conservators are Professional Associates of the American Institute for Conservation (AIC) and the Canadian Association of Professional Conservators (CAPC).  We offer decades of experience in the fields of conservation and historic preservation. The Conservators are supported by able Assistant Conservators, Administrators, and Technicians. We are constantly updating our comprehensive knowledge of innovative conservation techniques through attendance and presentations at national and international conferences and universities. This technics training is balanced with a breadth of experience in traditional craft skills used in the treatment of the extraordinarily broad range of conservation challenges we face; from masonry, metals and wood in buildings, monuments and works of art, mosaics, frescos, undersea and space artifacts, to industrial heritage. We collaborate with a network of specialized sub-contractors and industry experts in the areas of corrosion prevention, engineering, testing, biochemistry, metalworking, stonework, art foundries and the cleaning and coatings industries, who assist us with the design and specifications of custom solutions for unique and complex preservation projects.
