About Rehab Lab

A chiropractor that actually rehabs you

We were built on one question: why does this keep happening? Find the cause, treat it by hand, and rebuild how you move, so the pain stays gone.

Locations

Rehab Lab is a sports chiropractic and rehab clinic with two Wisconsin locations, in Wauwatosa and Appleton. We pair hands-on chiropractic care with real rehabilitation, so we treat the root cause of your pain instead of cracking you and sending you home.

Most people have been to a chiropractor who adjusts them, hands them a heat pad, and books them for next week. It feels good for a day, then the pain comes back, because nothing changed about why it hurt in the first place. That cycle is exactly what we were built to break.

Rehab Lab was founded by Dr. Sam Wagner because he is meticulous about the why. A former pro football player and board-certified sports physician, he wanted a clinic where the adjustment was the start of the plan, not the whole plan. Today Dr. Nate Williams leads our Appleton clinic with the same movement-first approach. You are treated by a doctor every single visit, no hand-offs to an aide.

Because we are a sports chiropractic clinic at our core, our doctors have worked with athletes at every level, from youth and high school programs to collegiate competitors and professional athletes in the NFL, NBA, MLB, and on the PGA Tour. That range is the whole point: the same care that keeps a pro on the field is what we bring to a high schooler chasing a starting spot, a weekend runner, or a parent who just wants their back to stop hurting. You do not have to be an athlete to be treated like one.

How it works

The Rehab Lab method

A clear, five-step path from your first visit to feeling and performing like yourself again.

01

Assess

A full movement screen (SFMA) and history, we watch how you move, not just where it hurts.

02

Diagnose

We pinpoint the actual root cause of the pain instead of chasing the symptom.

03

Treat

Hands-on relief: adjustments, ART, dry needling, Graston, laser, shockwave, and ARP Neuro Therapy as needed.

04

Rehab

Corrective exercise and strength work to rebuild how you load and move.

05

Perform

Return to sport, work, and life stronger, with a plan to stay that way.
