Professional from top to bottom. The ladies were clear and concise what documentation we needed to provide and handled as quick as you can imagine. Also great rates compared to other providers, we had applied when the Fed had announced interest rates will be increasing so their immediate response saved us a considerable amount of money. Thank you Members Source!!

Aniaya provided me with exceptional service while assisting me with opening a Save to Win account today. I became a member in 1992 and MSCU has been my primary financial institution ever since. Great products and great service. The front line staff assisting with deposit and loan accounts has always provided me with prompt courteous service through the years. They truly make you feel the “people helping people” philosophy. If you’re considering a credit union, they’re a great one!
