GuildQuality’s 2019 Guildmaster Award Honors Cornerstone Development
Sussex, WI — Cornerstone Development of SE Wisconsin LLC received a 2019 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 700+ eligible applicants, Cornerstone Development is one of 300+ businesses within the
residential construction industry recognized by GuildQuality for consistently delivering
superior customer care. In determining which businesses received the 2019 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 once again sincerely honored and humbled to be
recognized by GuildQuality with the prestigious 2019 Guildmaster Award,” said John Wahlen,
owner of Cornerstone Development. “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.”
