Dr. DJ Mortimer built this practice around a single belief: that every patient deserves the doctor's full attention, every single session — without compromise.
I grew up in Wisconsin, where sports were everything — and where I first understood what it meant to watch an injury sideline someone from the things they loved. That experience pointed me toward physical therapy, and I haven't looked back since.
I earned my Doctorate of Physical Therapy from Chapman University in Southern California, which also happened to be the perfect excuse to trade Wisconsin winters for San Diego sunshine. I fell in love with the beaches, the golf courses, and a community that takes an active lifestyle seriously year-round.
After years working in large outpatient clinics across the greater San Diego area — watching patients get passed between staff, squeezed into 15-minute slots, and limited by insurance visit counts — I knew there had to be a better way. In January 2023, I was published in the Physical Therapy Journal of Policy, Administration, and Leadership, reflecting my commitment to advancing the field.
In 2023, I founded Regenerate Physical Therapy and Performance to practice the way I always believed it should be done: one doctor, one patient, complete attention, every time. No assistants, no handoffs, no shortcuts.
Reliable, honest, and efficient physical therapy —
delivering exceptional care that puts people first
and supports lasting movement and health.
After years working inside large, insurance-driven clinics, I kept seeing the same problem: patients were getting less care than they deserved. Not because the therapists didn't care — but because the system didn't allow them to.
Appointments were rushed. Patients were handed off to aides. Visit counts were dictated by insurance, not by recovery. And through all of it, patients were told this was just how physical therapy worked.
I didn't believe that then, and I don't believe it now. I founded Regenerate PT to prove that high-quality, truly personalized care — where the doctor is with you from the first session to the last — doesn't just produce better outcomes. It produces faster ones.
The practice is built on the values I've held throughout my career: quality that doesn't cut corners, honesty about what it takes to get better, and a genuine commitment to the community I'm proud to serve.
Experience the DifferenceEvery decision at Regenerate PT comes back to these three principles — in the treatment room and out of it.
We practice with honesty, transparency, and ethical decision-making — always recommending what is best for the patient, not what is convenient or profitable. If something isn't working, we say so. If you don't need more sessions, we'll tell you that too.
We show up prepared, on time, and consistent. You'll never be seen by an aide or handed a generic exercise sheet. Your care plan, communication, and follow-through are reliable every step of the way — because your recovery depends on it.
We commit to high-quality, evidence-informed treatment and continuous improvement. That means staying current on the latest research, refining techniques, and ensuring every patient receives the best possible care — not just adequate care.
No commitment, no insurance headaches. Just Dr. DJ, your goals, and a real plan to get there.
