We are extremely pleased with Members Source Credit Union and our new car loan (below Prime 😎), plus Franchesca & Bryce at the Griffith office, and Gloria /Merrillville for talking us into the loan program! Kudos to your excellent, well-informed Staff!

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!!
