Our Dream

Momentum Therapy and Sports Specialists, LLC (the owner of Momentum TheraGym) provides therapy and sport specific services to the St. Louis, Missouri community. During her first 5 years as an outpatient physical therapist in Farmington, Missouri, Sarah Hasser, MPT came to  the realization that many problems as an adult can be avoided by the way one learns to move and play as a child. 

    The basic principles taught to gymnasts as a child when

taught to adults result in huge gains. These principles

are not age specific and are key to better movement

and improvements in the quality of life. Everyone can learn

to be a healthier mover regardless of age or ones state in life.

   Also, kids with special needs can make greater gains

when approaching the daily demands of life like an athlete.

Believing in the abilities of these kids and coaching them

toward goals helps to build their self-esteem, gives them ownership of the process and gives them happier, healthy lives.

   Our goal at Momentum Therapy and Sports Specialists, LLC is to give you the knowledge and tools you need to enjoy

moving well, all of your life through every service we offer. We are here to help kids of all abilities excel and reach new heights.
