Our History

Entellus exists because three individuals saw an opportunity. They worked together to seize that opportunity and, while they were at it, they built an amazing company dedicated to delivering success to our clients.

In April of 1985, three engineers, Ed Adair, Jerry Green, and Sam Kao, opened the doors of AGK Engineers, Inc. They took a chance, leaving their stable jobs to start their own civil engineering firm. They had no clients, no projects, and not one stick of furniture, but that first day they got right to work on building their dream.

Fast forward to today, over 30 years later, AGK Engineers is now Entellus, Inc., with multiple offices, six discipline groups, and over 60 talented employees, all working together to improve the communities in which we live, work, and play. We continue to embrace the can-do attitude and work ethic that enabled our founders to start with nothing but a store front office. Our talented professionals use insight and ingenuity to bring creative solutions to our clients' planning, design, and construction challenges each and every day.
