Testimonials
"From the moment I spoke with Robertson on the phone I knew that he and The Cassina Group were an amazing match for us. Robertson was consistently highly motivated, knowledgeable, professional, and communicative - all qualities I required in a broker.”
"Earlier this month I used Robertson Allen with The Cassina Group to list and sell my home. They not only made the process completely painless and smooth, they also helped me sell it in record time with their great marketing strategy! My home was under contract in 5 days after listing and I even received a back-up offer shortly thereafter."
"During the very involved sales process of my Mother’s family home on Queen St, time and again, I was grateful to be successfully represented by Robertson Allen and The Cassina Group. Robertson is an expert who knows, a professional who performs and a fine man of integrity you can trust."
"Robertson was incredibly helpful while we were looking for a house on Sullivan's Island. It can be very stressful and frustrating buying a house from afar and Robertson always kept us apprised of the situation/negotiations during the entire process. We were completely satisfied with our relationship with The Cassina Group and we feel that Robertson is not just our realtor, but a friend."
"We have purchased four properties and sold three in the Old Village of Mount Pleasant with the assistance of Robertson Allen and the team at the Cassina Group since 2008. If you smartly or luckily choose Robertson Allen you get an impressive team package. Robertson is knowledgeable, kind, intelligent and a wonderful listener....We think so much of Robertson and his credibility that we actually bought our current home in April of 2016 without even physically seeing it. He looked. He knew the house. He knows us. We just trusted him and we couldn't be happier."
"[W]e value Robertson’s knowledge, expertise, and professionalism. As two former attorneys and current investment advisers, we believe that--with respect to Robertson--our trust was extremely well-placed."
