Hi, I'm Ashlyn Tersigni!

I am a co-owner and practicing PTA here at Clash PTHS. My school background is quite interesting, we will say. I went to Salve Regina University in Newport, RI, where I majored in both biology and chemistry. I was indecisive between applying for medical school or physical therapy school. However, after spending my summers at home interning in an outpatient PT practice, I knew physical therapy was where my heart was happy. After graduating from Salve Regina University, I took some time off before attending Mount Wachusett Community College in Gardner, MA, for Physical Therapist Assistant. Once I graduated and was able to start carrying my own caseload, I was more than at home with my chosen career path.

I’ve been a practicing PTA for about 5 years now. I specialize in sports injury, chronic pain, as well as foot and ankle injury. I am an enthusiast for health and wellness. I want to get my patients back to their maximum functional potential without pain and without limits.  Therefore, I am always trying to learn more to broaden my skill set to help my patients

Some interesting things about me are I enjoy working out, hiking, and being outdoors, especially during the warmer months. My home away from home is Newport. I am an animal lover. I do enjoy reading books of all kinds. I am always trying to learn more and acquire more skills. 

I am confident the right person to help you get started towards taking steps to maximize your potential and start living your pain-free life.

Hi, I’m Sarah Clayton!

I am a co-owner and practicing Physical Therapist at Clash PTHS. I grew up on the cape playing various sports, but my original passion was basketball. I played 4 years of college basketball at Simmons, serving as captain for 2 years.

It wasn’t until about 7 years ago that I discovered my true love, which is rugby! I am the current Vice President of the Worcester Shamrock’s Women’s Rugby Football Club, the strength and conditioning coach, and an active player.

I was exposed to physical therapy early on due to sports injuries, which piqued my interest, and I never looked back! I am passionate about health, wellness, and functional fitness. I have earned a CSCS, Level 1 CFSC, and Level 1 Certified Barefoot Training Specialist and make continuing education a top priority to best serve my clients.

I love helping people tune into their bodies and empowering people with the tools they need to live a healthy, pain-free life. I truly believe that we shouldn’t place limits on ourselves, and when provided with the right tools, any goals are possible.  I am a well-rounded clinician capable of treating adults and adolescents with many diagnoses, from simple orthopedic to involved neurological. I specialize in foot function as it relates to all injuries.
