There are many reasons patients come to us for physical rehabilitation. One of the main reasons is because they have been hurt in an automobile accident and need additional attention in order to get their bodies back to feeling normal. Other people hurt their bodies in sports or work and need assistance to feel better again.

Dr.Marquez has been taking care of my family and I for 4 years now. He always takes excellent care of me and my back/hip issues. My kids love him as well, he works very well with my boys and they really enjoy being adjusted by him. He’s also so great about explaining everything and never makes you feel rushed. Great place to come!!!

Dr.Marquez is amazing he genuinely cares about you and making you feel better. He always goes above and beyond for his patients . My family loves him!!! I recommend that you visit his office.


Drove 2 hours from Chicago to get my lower back looked at and hopefully fixed. I met with Eduardo and explained my pain. He had a thorough look at everything and was able to pinpoint the problem. From there he worked his magic and now I am feeling amazing. 10/10 recommend visiting this place.
