A different kind of care — built around you
Innovare Tx Regenerative & Wellness Clinic is led by Charles Ortega, PA-C, MPAS — a Dallas native who brings both clinical and personal familiarity with orthobiologic procedures.
A provider with firsthand experience
Charles Ortega hasn't only studied orthobiologic medicine — he has been a patient too. Years of competitive soccer through high school and college took a toll on his knees, and multiple knee surgeries followed.
Charles chose to undergo a Bone Marrow Aspirate Concentrate (BMAC) orthobiologic procedure — an autologous procedure prepared from his own bone marrow, the same procedure now offered at Innovare Tx. That was roughly a decade ago.
That firsthand experience shaped how he practices. Since then, Charles has performed orthobiologic procedures for hundreds of patients and trained numerous providers in ultrasound-guided joint injections.
"He was very informative and found more than my initial visit last October back home. Very impressed with the level of care just passing through the area."— Kevin A., Zocdoc
PRP, PPP, BMAC, and A2M are autologous procedures prepared from your own blood or bone marrow. They are considered investigational and are not FDA-approved for the treatment of any specific orthopedic condition, including osteoarthritis. Individual results are not guaranteed. Any decision to pursue an orthobiologic procedure should be made with your provider after a clinical evaluation.
Experienced, integrated, and genuinely invested
Three providers who coordinate every aspect of your care — so your treatment connects instead of contradicts.

27+ years of real experience
Nearly two decades of primary care means Charles sees the whole patient, not just one joint. Years of occupational medicine built his expertise with work injuries and workers' compensation — expertise he applies today as a specialized OWCP provider in the DFW area.
Charles's areas of clinical focus include orthobiologic medicine (PRP, PPP, BMAC, A2M), weight management with compounded tirzepatide and compounded semaglutide, neuropathy treatment, OWCP / federal workers' compensation (CA-1/CA-2 claims for USPS, TSA, DHS, CBP, DOD, VA), family medicine, and veteran disability evaluations starting February 2026.

Dual-credentialed physical therapist
Rowena Calleja holds both a Medical Doctor degree and a B.S. in Physical Therapy — extremely rare in the US — with 4.5 years specializing in knee osteoarthritis rehabilitation.
