Meet the doctors

Sam founded Rehab Lab because he is meticulous about the “why.” A board-certified sports physician (DACBSP), he blends precise adjustments, soft-tissue work, and dry needling with a clear, progressive plan, guided by his belief that movement is medicine.

Nate leads our Appleton clinic, bringing more than a decade of hands-on experience from Denver to the Fox Valley. A movement-first clinician, he combines functional assessment (SFMA), dry needling, and IASTM to find the root cause and get you moving again, then keep you there.

A native of Northeast Wisconsin and former multi-sport athlete, Dr. Markowski earned his Doctor of Chiropractic from Palmer College and practiced for four years before partnering with Dr. Sam. He blends extremity work, dry needling, and movement assessment to find the root cause.

Dr. Mike Giammarco is a licensed Doctor of Chiropractic at our Wauwatosa clinic, where he treats patients with the same find-the-cause, hands-on approach the rest of the Rehab Lab team is known for.

Originally from Appleton and a lifelong athlete, Dr. Tony came to chiropractic after two season-ending injuries of his own. His evidence-based, movement-focused approach helps runners, lifters, and endurance athletes get back to what they love, and stay there.

From Kaukauna and a former college football and track athlete, Dr. Nick blends chiropractic with soft-tissue and rehab techniques. He earned his Doctorate with honors plus a Master’s in Exercise Science, and has practiced in the Milwaukee area since 2021.

A Green Bay native and Packers fan, Dr. Peda paired a Kinesiology background with chiropractic to treat athletes and active adults. He earned his Doctorate at Palmer College and practiced in northeastern Wisconsin for over four years before joining Rehab Lab.
