Stephan Rivas, ATC

Athletic Trainer

 I graduated Cum Laude from Illinois State university in 2015 and recieved my Bachelor of Science in Athletic Training. While attending Illinois State, I obtained 3000 clinical hours rotating several site rotations under various Certified Athletic Trainers. These sites included high school, NCAA Division I, and Division III sports. In addition, I completed a summer internship with the Chicago Bears in 2014 and spring of 2015. From there, I went on to receive a post-professional Master of Science degree in Athletic Training from Texas State University in 2017.  While attending Texas State University, I worked as a full-time Graduate Assistant Athletic Trainer for the university’s softball team. In the summer of 2017, I solely cared for the “Texas Charge” – a professional summer league softball team. I also have experience working with youth sports, industrial work sites, an outpatient physical therapy clinic, and two high schools including Corona Del Mar High School. I am a published author in three sports medicine journals. My treatment approach is centered on corrective exercises that are supplemented with soft tissue release techniques, stretching, and modalities. When I am not at work I enjoy surfing, exercising, and playing guitar. I am very grateful to be working with the athletes at CDM! I hope I add a positive experience to your child’s time here.
