Calling all overhead athletes!

How would you like to have a Major League Athletic Trainer create and monitor your arm care routine? 

Now introducing the "Total Arm Care Program!"  This program blends in-clinic hands-on sessions that focus on strength and mobility with the ArmCare app that creates personalized routines based on objective evidence that can be completed while at the field.

No longer will you need to do the same routine day in and day out not ever knowing if you are working on the areas necessary for you to succeed!

Don't need rehab but looking for Performance Enhancement?

Have you paid for or taken lessons that just don’t work?  Your instructor says do it this way and you physically can’t do it?  It’s not your fault!  Your neuromuscular system just doesn’t know any different.  That is my job it to re-teach your body to move in the way it was intended.  On the flip side it is part of my job to contact your instructor (if you give me permission) to find out what he/she is trying to get you to do.  Remember I have worked in baseball for 19+ years as well as specifically learned the ins and outs of a golf swing to help you meet your goals!

Do you need Rehab?

Have you gone to physical therapy for 6 weeks with no improvement?  Stretch, strengthen and repeat?  That is the old paradigm. If you have a loss of range of motion then more than likely you have a weakness in the opposite muscle group.  I KNOW! This is a true paradigm shift but it’s true.  The only way we can tell is for you to come in for an evaluation.




“I have known Matt for over 10 years now. He has helped me at every level in professional baseball. As my athletic trainer in the Major Leagues he helped me prepare my body on a daily basis with his unique skill set. Matt also excels at making the mind-body connection. I just tell him this is how I need my body to move for my desired swing and he is able to activate the necessary muscled so I can perform at my best.

I trust Matt and I highly recommend him to anyone that wants to move and perform better.”

Kyle Seager-Third Baseman for the Seattle Mariners


"Hello Everyone, this is Rick Griffin, I was the Head Athletic Trainer for the Seattle Mariners for 35 years and had the pleasure  of supervising and working along side Matt Toth for 14 plus years. He has a tremendous knowledge base in rehabilitation of all sports related injuries and his biggest strength is his ability to develop and prepare return to play programs for athletes who have suffered a repetitive injury or someone returning from a surgical procedure. Matt has excellent hands on skills including the use of Muscle Activation Techniques (MAT) which was widely used in our training room to treat shoulder, elbow, back, pelvic and lower extremity issues. Matt really cares about the athletes he treats and goes out of his way to listen to them and make them a part of the healing process which leads to increase trust and faster recovery times and a quicker return to the field of play."

What is Muscle Activation Technique?

According to Greg Roskopf, “Muscle Activation Techniques (MAT)® is a powerful muscular assessment tool that analyzes and corrects muscular imbalances. At MAT we focus on the cause of the imblance by testing, correcting, and maintaining muscle contractile efficiency. We believe that flexibility is a derivative of strength, and that muscle tightness is secondary to muscle weakness.

Our 77 Range of Motion Exams and 214 Muscle Tests help practitioners identify which muscles are not “firing” . Once the cause for the discomfort and impaired mobility is identified, practitioners begin a series of muscle tests in an established process and work to “reactivate” the affected muscles.”
