Functionize Health and Physical Therapy seeks to promote a more knowledgeable and healthier community where access to a high quality of care and maximizing one’s functional well-being is the top priority.

Why are we different?

We see treatment differently at Functionize Health and Physical Therapy.  We feel that our hands are our most effective tool.  Rather than rely primarily on modalities and exercise, we prefer a hands-on approach where we can feel and treat your problems. Providing you with individualized exercises that you can then complete at home will reinforce your treatment.  You can expect to receive extensive one-on-one hands-on treatment followed by instruction or review of functionally based exercises.  Time for questions and discussion is also allotted.  Through this approach, our clients can achieve better results in a much faster time period.

When you consider the time savings of fewer trips to the clinic and the value of resolving your problems more quickly than average, you are truly getting the “biggest bang for your buck” at Functionize Health and Physical Therapy.
