The Story Behind CLASH

Sarah and Ashlyn were an unlikely duo at first (or so it seemed).

Sarah being a more introverted, reserved person who was into rugby, and then there was Ashlyn, the self-proclaimed “bubbly blonde”, who was extroverted and obsessed with her cat.

Sarah never thought they would be friends, let alone business partners, but Ashlyn has the persistence of a golden retriever puppy, and a friendship was born.



They realized they have more in common than meets the eye, especially when it comes to how they see healthcare and aging.

They worked alongside each other in multiple clinics, always thinking the grass would be greener but quickly realizing it would never be that way.

Conversation after conversation discussed the holes in patient care.

  • The disempowering language used to talk to patients
  • Keeping patients in the dark because they didn’t have the time to fully educate them
  • The ways they were limited with their interventions
  • How the current system prevents clinicians from connecting with their patients in a way that makes a real difference.

They knew something new was needed!

They often talked about opening a clinic and taking a different approach.

Then one night (at Countryfest, of all places!) Ashlyn jokingly put their names together and exclaimed we’re Clash!

Sarah (Cla)yton + (Ash)lyn Tersigni = Clash

They sat on it for a while, but when COVID hit, there was ample time to think about what they wanted from life, and they knew it was now or never.

They took the leap, and Clash stuck!

It also ironically felt good because they are “clashing” against the modern biomedical model to create holistic, lifestyle-based treatment plans to give people long-term solutions, not just temporary relief.

They share a mission to empower people to improve their total health, and never treat people as a diagnosis or a body part.

They believe wholeheartedly that the human body is resilient and has a great capacity for healing. Clash’s mission is to help people realize this, feel less helpless when it comes to pain, and truly start to thrive!
