You're totally right, Praescient does a lot of cleared work and HR is definitely one of the main people we communicate with onsite to help answer company questions for things like payroll, healthcare, security clearance stuff, travel, etc... HR is really good. She is super approachable and if she doesn't have the answer she will find it and get back to you ASAP.
In my experience HR was turning over *very* frequently. So your only company contact is your contract manager. Most are sent onsite with a wave and a contact email if there are problems.
HR is ever changing. As it turnover in my experience.
