Executive Vice President – Marketing and Human Resources

Ms. Berkopec has held operational, marketing and human resource management positions in the automotive manufacturing arena,  Tier 1, 2, 3 supplier support services and health care services.  She has developed and initiated innovative concepts in areas of operations, human resources and customer service.

As a Division Vice President at AMC/Chrysler, she was responsible for staffing technical, administrative and engineering positions within AMC.  At the same time she directed her staffing subsidiary’s emergence as an independent profit center while maintaining supplementary staffing needs within the corporation itself, an innovative and successful concept at the time.

As a Human Resource Manager, Patricia has been responsible for recruiting, placement and supervision of thousands of individuals in administrative, engineering and technical positions in every type of service and manufacturing operation in S.E. Michigan.  These challenges and successes inspired her to develop and teach her own Employability Skills curriculum in a local school district.

Her background also includes several years spent in the health care field where she established and promoted community-based disease prevention and educational programs throughout Michigan.  She was a pioneer in introducing mobile cardiovascular screening programs across Michigan’s Upper Peninsula.  This concept, unique and ground-breaking at its introduction, has become a widely accepted and effective method for reducing stroke and cardiovascular disease in areas lacking such technology.
