From the very first appointment, Dr. Minges was very honest and forthcoming and wasted no time. Considering I have previously had a lumbar fusion, which was very serious after deciding on treatment, and ultimately having another operation. He cleaned up everything from the first operation, fixed the new issue, and rebuilt the cage around my spine. Within 24 hours of being home from the hospital, I was off all medications, had zero side effects, and zero complications. I would 100% absolutely recommend Dr. Minges!

Satisfied Lumbar Fusion Patient

Had bulging disc in lower back. Pain rating was very high when it started. With Dr. Minges' help, I am back to doing what I was able to do prior to my injury with minimal to no pain. Really appreciate all that he has done to help me continue doing the things I love.
