A Charleston native, Robertson loves the Lowcountry and everything this one-of-a-kind city has to offer. He currently lives with his wife and two sons in the town of Mount Pleasant.
Robertson graduated from Clemson University with a marketing degree and has worked in the Charleston real estate market since 2002. In that short period, Robertson has become an annual multi-million dollar producer and a multiple year recipient of the Realtor of Distinction - Executive Circle award .
In the Spring of 2006 Robertson partnered with Jimmy Dye to form The Cassina Group, LLC and the company is now one of the areas leaders in residential home sales.
He works tirelessly to find the "right addresses" for his clients to ensure that they will love Charleston as much as he does.
Robertson has closed over 175 million dollars in his career in real estate and since 2011 ranks in the TOP 5 for homes sold over 2 million dollars and TOP 10 for homes sold over 1 million. Robertson takes great pride in assisting clients who are searching for Charleston's most exclusive properties.
"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."
