Among the many clients Cornerstone Construction Group has had the privilege to serve are Providence Little Company of Mary Hospitals, Children's Hospital of Orange, St. Vincent Medical Center, Riviera Property Management, Honda Federal Credit Union, Los Angeles Job Corps Center, and Robinson Helicopter. 
 
Since 1985, Cornerstone Construction Group has worked in sensitive healthcare environments where patient care is maintained while construction takes place. 
 
We train employees to understand that environment--how it works--how to conduct themselves so that our clients--whether they are healthcare facilities or not--benefit from the most sensitive construction works and careful work practices. 
 
One facility manager said, "Often someone like me has to put together a punch list--I will look over the whole job and note things that are missing. With Cornerstone, you won't have a punch list--everything will be completed. When we do a final inspection, items have not been forgotten or overlooked. They are a service provider that pays attention to every detail."​ 

Health Care Facilities 
Cornerstone has extensive experience in hospital construction. We pay special attention to how construction will progress throughout the facility and how it will impact ongoing patient services. We look for alternative methods that are less intrusive for patient care. 

Commercial and Industrial 
Cornerstone has over 38 years of experience serving commercial and industrial clients. As a service-oriented company, we understand and facilitate the special needs of each client. Cornerstone will prepare customized budgetary figures and project schedules.
