Meet the doctors
At Rehab Lab you are treated by a licensed Doctor of Chiropractic every visit, no hand-offs to an aide. Meet the team behind the care across our Wauwatosa and Appleton clinics.
Our doctors come from sport, science, and a stubborn belief that the adjustment is only half the job. Each one pairs hands-on chiropractic care with real rehabilitation, so we fix the root cause and rebuild you stronger. Tap a doctor with a full profile to read more.

How do I choose which doctor to see?
For most problems, any of them is a good answer, and the front desk will match you to whoever is at your clinic with availability. If you want someone with a specific focus, such as extremity work or hockey-related hips, say so when you call.
Will the same doctor treat me each visit?
Yes. One doctor owns your plan from start to finish, which is how the plan actually progresses. If your doctor is away and you need to be seen, the notes are shared so whoever sees you knows exactly where you are.
Are all of your doctors licensed chiropractors?
Every one, and you are treated by a Doctor of Chiropractic at every visit rather than handed to an assistant for the second half of your appointment. Individual credentials are listed on each bio and on our trust page.
Can I request a specific doctor?
Yes, and plenty of patients do once they have seen someone they like. Ask when you book. The only caveat is availability, so being flexible on time helps if you are set on a particular person.
Which doctors work at which clinic?
Each bio names their clinic. Broadly, the team is split between Wauwatosa and Appleton. Dr. Sam is the exception, moving between both rather than practicing at one, and seeing patients by application only.
Do any of your doctors treat children or teenagers?
Yes, and youth sports injuries are a regular part of our caseload. Technique and expectations are adapted for a growing body, and we are direct with parents when the real problem is training volume rather than an injury that needs treating.
