Our team

- Treatment philosophy -

At Laws of Motion Physical Therapy, our philosophy is to treat the client walking through the door, not their diagnosis. On any given day, there could be 10 patients who walk into our clinic with complaints of lower back pain and we could use 10 different treatment methods to treat those clients.

Every client receives a full evaluation of all systems and we treat the entire body to find the root cause of their symptoms and achieve best results. Regardless of diagnosis, there are no cookie cutter injuries and therefore there should never be a cookie cutter approach to treatment.

We achieve this by looking at the body in three categories: mechanical, neuromuscular, and motor control

Mechanical capacity is the ability for your joints, muscles, fascia, skin, arteries, veins, nerves, viscera and everything else to move freely and with efficiency. We use a variety of manual therapy, modalities and exercises to help improve the mechanical capacity of your body.

Neuromuscular function assesses the initiation, strength and endurance of muscles and enables proper mobility by providing stability in the system. We use a variety of exercises and Proprioceptive Neuromuscular Facilitation (PNF) to help restore proper mobility and stability.

Motor control addresses posture as well as movement and lifting strategies that are necessary for optimal, pain-free living.

When you attend a therapy at Laws of Motion, look forward to a methodical approach to treatment that includes restoring pain-free movement, optimizing movement, enhancing physical capacity and maintaining proper function.

Greg Law PT, DPT, CFMT Physical Therapist, & Owner

Greg is originally from Illinois but made his way to Phoenix in 2011 to attend physical therapy school at Midwestern University in Glendale, Arizona. He graduated from Western Illinois University with a bachelor’s degree in marketing and minor in supply Chain management and worked in the sales and logistics industry in Cincinnati, Ohio. After four years in this industry, he realized this was not his calling. After going through his own round of physical therapy following shoulder surgery, he developed a drive to help others as he was helped and returned to school to study physical therapy. In 2009, he began classes at the University of Cincinnati taking physical therapy prerequisite classes and was accepted into physical therapy school in 2011. During his time at Midwestern, he met several physical therapists that became mentors to him and steered him toward becoming a manual therapist. Manual therapy holds a special place for Greg as it is a way to directly help patients achieve their goals by correcting movements, guiding patients and  enabling him to have the greatest impact he could have on his patients. After graduating, he moved to Dallas, Texas, to open two clinics with Ideal Physical Therapy where he was a part of a dynamic team that helped his clinic grow the fastest of the original five clinics in the Dallas/Fort Worth area. In 2016, he moved back to the Valley of the Sun but not before meeting his future wife in Texas. Once back in Arizona, he stayed with Ideal Physical Therapy/ATI for a few more months prior to joining Barrow Brain and Spine in 2016. In 2018, he was promoted to manage the Barrow Brain and Spine Ahwatukee outpatient clinic where he guided the PT program through the recent acquisition and grew the clinic from two therapists to four in a few short years.


Throughout these experiences, he has dedicated himself to gaining as much knowledge and practice as possible in physical therapy taking approximately six continuing education classes per year with companies such as the Institute of Physical Art, the Barral Institute, the Titleist Performance Institute, the Spinal Manipulation Institute and several others. In 2018, he graduated from the Institute of Physical Art’s certification program with honors, becoming a Certified Functional Manual Therapist (CFMT). He is also certified to perform dry needling, has a nutrition certification through Precision Nutrition and certified through multiple levels of the Titleist Performance Institute.


In his spare time, Greg enjoys spending time with his growing family. He and his wife Heather welcomed their first child, Harper, into the world in late July 2020, have welcomed their second child, Cooper, in April 2022, and also have a miniature Australian Shepherd named Oliver. Greg also enjoys the outdoors and being active. He enjoys playing golf, basketball, hiking, weight training and playing guitar. Physical therapy has been a great passion in Greg’s life and he looks forward to serving you and your needs to help you achieve your potential.

Heather Law PT, DPT, ATC Physical Therapist, & Owner

Heather first became interested in becoming a healthcare provider after undergoing multiple medical procedures in high school and experiencing first-hand what an impact it made working with healthcare workers who treated it as a job versus those who had a passion to really help their patients. Since then, Heather has been driven to become a lifelong learner dedicated to providing exceptional care that meets her client’s individual needs. She takes a whole-body approach to providing answers and care to every client, no matter how complicated their dysfunction is, and wants all of her clients to live their most optimal life.  


Heather grew up in Colleyville, Texas, and attended The University of Texas at Arlington where she graduated summa cum laude with a Bachelor of Science degree in athletic training in May 2013. She then attended UT Southwestern Medical Center in Dallas, Texas, for a doctoral degree in physical therapy and graduated with honors in 2015. Throughout PT school Heather worked as a contracted athletic trainer providing medical coverage for various athletes and sports throughout the Dallas/Fort Worth Metroplex. Following PT school, Heather began her career in an orthopedic/sports medicine private practice called Ideal Physical Therapy/ATI. This is where she first met her husband Greg who persuaded her to move to Arizona. After two years with Ideal/ATI, Heather began working at Barrow Brain and Spine in 2017. While there, she gained critical experience working primarily with patients with spine disorders, neurosurgical patients and patients with chronic pain.


After having her daughter Harper in July 2020, Heather became aware of lack of prenatal and postpartum care and the effect it had on her own body. This launched her passion to pursue training in pelvic health physical therapy that grew further after having her son, Cooper, in April 2022. So much attention is given to making sure the baby is well looked after that the mother’s health is often overlooked. Heather wants to change that and ensure that moms are able to enjoy every moment with their baby without being burdened by pain and injury. 


Heather has additional training in trigger point dry needling from Spinal Manipulative Institute and Evidence in Motion, Visceral and Neural manipulation from The Barral Institute, Functional Manual therapy from the Institute of Physical Art, pelvic health via Herman and Wallace, as well as various other institutes as Heather enjoys attending at least four continuing education courses per year. She also has her nutrition certification through Precision Nutrition and developed a passion about learning about the benefits of healing through nutrition and lifestyle change as this has made a significant impact on her health over the last few years. 


Heather looks forward to working with you to fill in the missing pieces to your health and recovery so you can reach your untapped potential.
