Our Team and Customer Service... A Key Element of Success

What makes GDI and it's team unique is their extraordinary commitment to customer service. GDI limits the number of projects to a select few each year. This allows our company and our team to provide hands-on management of each project, guarantees the quality of their homes, and affords a level of customer service unmatched in this market. At GDI, customer service begins with your first contact, and continues throughout the entire building process, and for decades that follow. Jan Hanzl is proud of the ongoing relationships he has with clients long after the project has been completed. Referrals from satisfied clients are GDI's best source of new and repeat business.
