Very Positive Experiences; Recommended

Posted by: |

I was introduced to St Mary's when I applied for a zero-percent energy loan to replace my failed furnace. This occurred during the height of the pandemic and the experience was outstanding. The paperwork was ready when I arrived, and everything was executed in record time.
Fast forward two years and I, like many others, have begun seeking alternatives to other central MA-based CUs that are flailing. Without an appointment, I went into the local branch and set up a series of checking and savings accounts working with the branch manager. Exceptional service.
When I used the #800 number, again, exceptional service.
This is a financially strong institution with excellent service and outstanding service.
Highly recommended.
