  • My business philosophy is built on integrity and professionalism. I have built my business on my knowledge of the markets I service.
  • With our Internet marketing program, I’m determined to generate broad online exposure for home sellers at America’s leading real estate internet sites and portals, selling homes quickly and for the best possible price.
  • To satisfy online home buyers, my listings have multiple photos and detailed property descriptions, two of the most sought after features by online home shoppers.
  • I provide superior customer service to home buyers with LeadRouter, our proprietary software, which allows me to respond immediately to inquiries from online buyers interested in any of my listings.
  • To tap into the masses of Internet users searching for homes, Coldwell Banker Residential Brokerage continually purchases thousands of search terms on some of the Internet’s biggest search engines to drive home buyers to my local listings.
