My appointment isn’t until 8/19/26, tomorrow, but after reading over the reviews I’m gonna go ahead and bet all 5 stars that I was right to choose them. After reading the very first review posted here from Rachel, we had the same fears and worries! But i believe im in great hands! I’ll return at the end of this path to healing to provide a follow up!

Dr. Groff and his team are wonderful, caring and very knowledgeable! I came in with extreme neck pain and migraines due to disc degeneration in my neck. It impacted my life almost daily. The spinal decompression therapy along with their guidance on home care have helped me get back to enjoying life! I cannot recommend them enough and will definitely use them for any future needs. So thankful a friend recommended them after they helped her!!

I cannot say enough about Dr Groff and his knowledgeable staff!! Since my 20s I've struggled with lower back pain due to sports, heavy weight lifting and just not taking care of my body. When my back locked up, most of the time I'd just lay on the floor until the pain was bearable and it would eventually just go away. Tried PT a few times and while that helped it didn't resolve my issue. Now in my 60s my body just doesn't respond like it use to and I couldn't shake my latest back pain. Being totally against surgey, I decided to give Dr Mark Groff and his team a try. In my initial consultation with Dr Groff, I realized I'd made the right choice! My lower back issue was explained in detail, language I understood, and backed up with stats. "The what and the why" was laid out there and so was the plan to fix/heal me, not just get me pain free. Throughout my treatment I could tell my back was responding in a very positive way ... something totally different than I had experienced before. The decompression process just makes since once you're educated about it and your personal situation. Now, just a few days ago my 20 year old son landed in the ER with pretty much the same lower back issue but more severe. We were transferred to another ER and ALL we heard was surgery was needed. Respectfully, we wanted a second look and of course my experience lead us to Dr Groff and staff. After looking at my son's MRI, Dr Groff said we can heal you without surgery. With no pressure and full understanding, my son made his decision to go with decompression therapy as well ...it just made sense. Now he's confident he is on a healing path and in better spirits knowing surgery wasn't the only option.

I just finished my last treatment yesterday, as Dr. Groff put it, I graduated, and I feel amazing! Dr. Groff and the entire staff are absolutely the best people. Every question I had during my treatment was always answered, whether by Dr. Groff himself or one of the friendly staff members. I can’t express how much I appreciate them and how grateful I am to finally walk again without pain. Thanks to their care, I’ll be able to ride my Harley again by next spring without hesitation! If you’re experiencing any kind of pain, I highly recommend Disk Center of America in Gallatin. They truly gave me my life back!

I recently had the pleasure of receiving treatment from Dr. Groff and his exceptional team, and I can't recommend them highly enough! After struggling with persistent lower back pain, I decided to try spinal decompression therapy. From my very first appointment, Dr. Groff was attentive, knowledgeable, and genuinely cared about my well-being. He explained the procedure thoroughly and set realistic expectations. The entire team was professional and supportive, making each visit comfortable and reassuring. After several sessions, I noticed a significant reduction in my pain, and I finally feel like I can get back to my normal activities. Thank you, Dr. Groff and team, for your expertise and dedication—you’ve truly changed my life! Five stars all the way!

Just for starters I am the biggest skeptical person. When I talked to Dr groff I was thinking no way this was going to work. I am glad to say I tried it. The staff were all very nice and treated people like family and not just patient. If I had the same problem as before I would do it again.

Dr. Groff and his staff gave the best care. He will give you his honest opinion and will stick with you if you still need therapy beyond the predicted amount of visits. Great Christian environment too!!!
