Cornerstone Development Wins 2017 Guildmaster Award


GuildQuality’s 2017 Guildmaster Award Honors Cornerstone Development

Sussex, WI   Cornerstone Development of SE Wisconsin LLC received a 2017 Guildmaster Award from GuildQuality for demonstrating exceptional customer service within the residential construction industry.

Since 2005, GuildQuality, an Atlanta-based third-party customer satisfaction software surveying company, has powered the Guildmaster Award to recognize and celebrate home building, remodeling, and contracting professionals demonstrating the highest level of customer service within the U.S. and Canada.

Out of 600+ eligible applicants, Cornerstone Development is one of the businesses within the residential construction industry recognized by GuildQuality for consistently delivering superior customer care.  In determining which businesses received the 2017 Guildmaster Award, GuildQuality reviewed thousands of survey responses submitted by customers of Guildmaster candidates, and considered two primary metrics for each candidate: the percentage of customers stating they would recommend the business to friend and the percentage of customers who responded. Cornerstone Development achieved a recommendation rate of 90% or above from their customers surveyed by GuildQuality.

“We at Cornerstone Development are honored and humbled to be recognized by GuildQuality with the prestigious 2017 Guildmaster Award,” said John Wahlen, owner of Cornerstone Development, an Epcon Community developer. “We develop ranch-style condominium neighborhoods offering exciting opportunities for our home owners to improve their 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.”
