About DSC Performance

The clinic that treats the cause.

Most clinics manage your symptoms and hand you a plan that never ends. We built this place to fix the cause: one-on-one with a Doctor of Physical Therapy, every single visit.

Our Story

This isn’t our story. It’s yours.

Portrait of Kevyn Dean, founder of DSC Performance

Kevyn Dean, PT, MSPT, OCS, Founder

DSC started in 2002 with a handful of up-and-coming surfers and one belief: nobody should have to choose between getting out of pain and getting back to what they love. Kevyn Dean had already spent a decade closing that gap, first in Northern California, then here in San Clemente after the ocean pulled him west in 1991.

He built DSC around the way he wished every clinic worked. One-on-one with a Doctor of Physical Therapy, every visit. A cause-first evaluation instead of a guess. What began as surf performance training grew into a full clinic, because the same approach that gets a pro back in the water gets a parent back on the floor with their kids.

Kevyn is the founding medical director for the USA Olympic surf team. But the person he built this place for is you: the one who has been quietly working around the pain, hoping it sorts itself out. The people who do best here are the ones who fix things: their houses, their teams, their families. This is where they finally fix the thing they’ve been putting off: themselves.

“I treat Olympians and grandparents the exact same way: find the real cause, build a plan with an endpoint, then earn the comeback together.”

What We Believe

Four things we’ll never compromise.

Your PT time. Dedicated.

Every visit includes dedicated one-on-one time with your Doctor of PT for hands-on treatment and direct care. Our aides and technicians support the rest of your session, so nothing gets rushed.

Cause first. Symptoms follow.

You’ve chased the ache itself before and never found where it started. We find the why first. Then it stops coming back.

Plans end. That’s the point.

You shouldn’t need a punch card. Every plan has a graduation date, so you always know how close you are.

You’re not a protocol.

Your job, your body, your goals. That’s what your plan is built around, never a generic sheet.

The Difference

Not your typical clinic.

A typical clinic

  • You explain your pain to a different person every visit
  • Hands-on time with your therapist gets squeezed in between other patients
  • The same pain creeps back in a few months
  • No graduation date, just book again next week

DSC Performance

The longer you manage it, the more it costs you. Feel the difference in your first visit.

Rooted in San Clemente

One town, one physical therapy clinic.

This is our neighborhood too, and we treat San Clemente like the hometown it is: your neighbors, your teammates, your kids’ coaches. The mom who’s been pushing through it so nobody else has to worry? She’s probably on our schedule too. Recovery is a lot more personal when it’s local.
