Live pain free

We help our patients stay active, healthy and pain free with holistic chiropractic care.

Your best life is waiting.  


Our mission is to help you live a healthy, active life free from pain.

With two conveniently located offices in Oak Park and Carpentersville, we help people of all ages and abilities get back to optimal health through the use of holistic chiropractic care.  Dr. Tammy has over 20 years experience helping people achieve (and exceed) their health goals and has experience successfully treating a wide range of health conditions. 

Receiving care at our office is a pleasant and relaxing experience.  Appointments are not rushed and each patient gets ample time to speak with Dr. Tammy.  After an initial consultation, Dr. Tammy will create a customized treatment plan to help you get back to optimal health.  Treatment may include chiropractic adjustments, physiotherapy, acupuncture, massage or nutritional counseling.  Most patients find relief after the first visit, but some conditions need additional visits to achieve full recovery.
