Andrew took the initiative to pursue us as a client and then professionally assisted us until the job was done. The care and connection he had to this deal was impressive and enabled us to move forward deliberately and confidently knowing that he had our best interests at heart. His experience and negotiating skill were quite obvious from the start and proved to serve us well. He took the initiative to thoroughly research the market as our tenant rep and found a perfect off-market space for our company.
