Sussex, WI – For the second consecutive year, Cornerstone Development of SE Wisconsin LLC has received the Guildmaster Award from GuildQuality, an Atlanta-based third-party customer satisfaction software surveying company. The award “recognizes businesses within our community of quality who consistently deliver exceptional customer experiences.”

After applying, in order to receive the award, a Guildmember such as Cornerstone must, at a minimum, achieve both a 90% recommendation rate and a 50% customer response rate.  Since 2005, The GuildQuality Guildmaster Awards recognize and celebrate service excellence among home builders, remodelers, developers, property managers, home services contractors and real estate professionals within the U.S. and Canada.

“All of us at Cornerstone Development of Southeast Wisconsin are honored and humbled to receive the 2020 Guildmaster Award,” said John Wahlen, owner of Cornerstone Development. “Receiving this award signifies and validates our company’s commitment to maintaining the highest quality building standards for each of our condominium neighborhoods while, at the same time, conducting our business in a fashion that delivers the best possible customer experience. We help people to build exceptional, exciting lifestyles. To have such a high percentage of these buyers recommending Cornerstone Development to their friends means a great deal to everyone on our team.”

In granting awards, GuildQuality considers two primary metrics for each candidate: the percentage of customers who would recommend and the percentage of customers who responded. Incorporating a high response rate into the calculation enables us to confidently recognize top performing companies, however, in many cases, some companies will receive very high customer satisfaction scores but may not qualify because too few customers responded to a survey.
