Andrea Mates has been a teacher in various capacities for 20 years and recently transitioned to teaching strength training with barbells. In 2013 when she nearly dropped her then 3-year-old daughter, she realized she wasn't strong enough for her mom duties. After reading Starting Strength: Basic Barbell Training, she taught herself the lifts and became stronger than she ever thought possible. When Starting Strength Austin opened in April 2019, she was recovering from a long illness and joined to be coached back to strength. In October 2020, she became an Apprentice Coach at the gym and completed the Starting Strength Coach credential in November 2021. Andrea has a doctorate in Applied Linguistics from UCLA and bachelor's degrees in Russian language and Public Policy from Duke.
Jeff began training with the Starting Strength method in 2020 and began work for his SSC credential in 2021. He started training to alleviate back pain from an injury, and after the program fixed his back to got him stronger than he had ever been, he began training as many people with the method as would listen. Jeff likes seeing people transform as they get stronger, especially those who never saw themselves enjoying barbell training. He has a doctorate in Biomedical Sciences from the Icahn School of Medicine at Mount Sinai, postdoctoral training at ETH Zurich, a Bachelor's in Cellular Biology and Japanese from San Diego State University.
David has spent the last decade providing bodywork and massage therapy. In that time he worked with thousands of bodies from stay at home moms to professional athletes. In September of 2020, David worked with a client who had muscle mass and a tissue feel unlike anyone else. The client was a member at Starting Strength Austin. This inspired David to join Starting Strength Austin as a member. During that time he experienced drastic changes in his body and a huge improvement in his quality of life. He then decided to pursue the Starting Strength Coach credential in order to teach the method and help others experience the same life changing improvements. David completed the credential in July 2022 and is now coaching the Starting Strength method for the Austin area.
