"I opened my business after 3 years of working at the typical 'PT mill' with juggling 3 to 5 patients an hour.  So my clinic is now based on NOT being the typical and the first step is spending time with each patient.  So I chose to offer one on one, hour long appointments to address reaching the goals of each individual.  This allows me to learn about the body on each visit in a continuous assessment and treatment progressive approach.  With the home release program and awareness training, I teach patients to empower themselves to improve."

Megan was a competitive gymnast when she was younger and spent most of her free time in the gym. After stepping away from gymnastics to focus on other goals when she was 15, her body started breaking down and she suffered from chronic pain, adrenal fatigue, seizures, as well as anxiety and depression. She struggled for 15 years with these issues before discovering Pilates. Megan found that mindful movement assisted in releasing the energy that was trapped in the muscles and has allowed her to manage her fibromyalgia and create a new life that is no longer dictated by physical constraints. She discovered CORE while searching for a Pilates training program that took a therapeutic, whole body approach to movement. She immediately felt at home in the CORE Studio and enjoys watching the transformation of the clients as they find relief from pain and return to the things that they love.

Megan’s goal when working with her clients is to help them with the following. To connect their breath with the body using movement and awareness to release energy that gets trapped in the body. To provide education of the body mechanics to better aid in recovery and prevention of injury. She looks forward to exploring movement modalities that assist the body in releasing stored trauma and helping her clients become aware of the mind-body connection that is necessary for whole-body healing to occur.

Liz came to CORE in 2013 as a physical therapy patient searching for relief from chronic back pain. Scoliosis, a sports injury, and living in New York City left Liz constantly defending herself from re-injury and feeling like she could never quite get over the hump to find relief. She decided to move back to Austin to return to a more even keel lifestyle and to get down to business finding a way to live her life to the fullest, without fear of pain. Through physical therapy at CORE, Liz was introduced to Pilates and quickly realized it was a highly effective and achievable exercise regimen for injured and healthy bodies alike, and anyone in between. Through her training and personal Pilates practice, Liz has been able to find a much deeper understanding of the body, how it connects, and how it moves through pain. Liz completed her Pilates training with Cheryl in August of 2018 and is working as an apprentice instructor at CORE, teaching group Pilates classes and private sessions. She is amazed at the endless bounds of knowledge and technique to be found in the Pilates method and looks forward to helping CORE clients find their strength and a healthier sense of well-being through this movement practice.
