If your chiropractor isn’t assessing joint mobility, they’re guessing. At Peak, we assess. We analyze. We correct.

Struggling with back pain? 👉 follow

If you’re current chiropractor only adjusts you and then does 2 mins of Theragun…it’s probably time you find a new chiropractor.

At Peak Performance, we conduct a full body assessment joint by joint.

We find the weak links and joints that aren’t functioning properly and treat the root cause of the pain.

We integrate FRS (Functional Range Systems) Mobility Training, (PRI) Postural Restoration Institute, Stemwave treatment, Adjustments, Soft Tissue trigger point work, and strength training.

We can help you solve issues related to:
• Low Back Pain
• Disc Herniations
• Sciatic Nerve Pain
• Stenosis
• Hip Impingement
• Frozen Shoulder
• Gluteal Tendonitis
• Bicep Tendonitis
• Tennis Elbow
• Golfer’s Elbow
• Rotator Cuff issues
• Neck Pain
• Cervical Stenosis
• Headaches

You’ll feel better on our treatment table.
And you’ll stay better with assigned mobility exercises you can do at home.
