Congratulations to the GES Team!

GES is excited to announce that we have added another trophy to our collection. GES was awarded the first place 2015 Best Places to Work in Southern Nevada award by Southern Nevada Human Resources Association (SNHRA). The 14th annual awards banquet was held on October 9, 2015 and was attended by nominees, association members and guests.

SNHRA’s “Best Places to Work” awards program recognized top southern Nevada employers for innovative human resource practice3s and programs. This award is special to GES being that the reason for our win is based on all the wonderful feedback we continuously receive from staff throughout the year. Jennifer Beezer, GES Administrative Manager, utilized feedback from past employee surveys to implement and/or enhance benefits, policies, and procedures making GES an even better place to work.

“We are honored to once again be recognized by the Southern Nevada Human Resource Association as one of the best companies to work for. With a vision to be the premier geo professional organization in the southwest where the best people in our profession want to work and to consistently meet our profitability targets, for me, it demonstrates that we are on the right track. At GES we take great pride in our positive work environment, our strong family culture which fosters and supports leadership, integrity, service and teamwork.” said President/Owner Greg DeSart.
