What our clients think

"I want to express my gratitude to Claudia Payan, Montse Rosas, Wendy Henriquez, Eva Mora, Laura Lopez, Blanca Coronado, and the strong leadership of Manuela Lopez for all their hard work and dedication to making the University sparkle and a welcoming environment. These loyal women bring their positive “can do” attitude to work every day. They are ALL willing to go the extra mile when needed.


This semester, with more students back in the building, they have to promptly respond to more urgent calls and they all do it diligently with a smile. The level of initiative to follow up with projects and report concerns immediately is much appreciated. We are very grateful to have this crew working at the University.


CSG should be proud of hiring each one of you knowing that they have exemplary employees representing them..."

Norma, Assistant Director, Operations
