Our company decided to leave our PEO provider in order to gain better internal controls and personalization. This was not an easy proposition. After much research, we chose Commonwealth Payroll & HR and with the support of their staff, we have completed our transition. Each and every team member is professional and dependable. We have designated staff members assigned to our account that have been available at a moment’s notice. They are consistent and knowledgeable. We couldn’t be more delighted!
