The Essex Regional Retirement System (ERRS) is comprised of 48 employers.  ERRS has created this page specifically for our employer units to assist in managing our member's accounts and to provide you with up-to-date information on retirement issues.  With two separate pension reform acts signed into law in the last three years, we recognize the challenge the new and changing retirement rules place on our system's employers.  We hope you will find information on this website and especially on this page that will help you in meeting the retirement needs of your employees.

If you have questions about pension reform, financial issues, or general retirement-related questions, please feel free to contact the Executive Director, Charles Kostro.  Mr. Kostro's contact information is listed above.

If you are a payroll coordinator for one of our system's employers and you have a question related to retirement deductions or membership eligibility, please feel free to contact our Membership Coordinator, Kenneth Mayne.  Mr. Mayne's contact information is also listed above.
