On 7/18/2025 Danielle Hughson had this to say:
Mike took my grandma and auntie’s diamonds and helped me create two absolutely stunning pieces that I can wear everyday to remember them. I know it’s not easy working with really old stones, and Mike did an absolutely beautiful job. He’s also fixed my watch perfectly. Highly recommend Mike!

On 1/16/2025 wilson stemm had this to say:
Now under new management, this business will continue on as it was before, by a sole owner. So many Louisville traditions have disappeared, gobbled up by corporations. This local business is worth rediscovering for custom jewelry and jewelry repair. The proprietor, Mike McDonough, has been fair and honest in all of my dealings.
