I worked at giatech for 4 years as an estimator/predictor before it was acquired by Pinnacle in 2015 (and renamed from Project Architect).
It has been another great experience there! The people were amazing - everyone cared about our needs & wants vs what we thought those would be when hiring them / interviewing us initially. We had some of best project managers out here that made sure everything went smoothly while managing large crews across multiple states.
There is nothing really negative
