Christopher Marker, DO brings board-certified physical medicine and rehabilitation credentials to Carlsbad's Aviara corridor, practicing at San Diego Orthobiologics Medical Group on Paseo Del Norte near the Carlsbad Premium Outlets. His subspecialization in sports medicine complements an orthobiologic focus that includes platelet-rich plasma, autologous bone marrow concentrate, and micronized adipose tissue transfer — techniques he deploys alongside providers such as ProActive Physical Therapy & Sports Medicine for post-injection rehabilitation protocols. Trained at NYU-Langone Medical Center in New York, he earned membership in the American Medical Shockwave Society and has lectured at multiple national orthobiologics conferences as a faculty presenter. Shockwave therapy applications at the practice target plantar fasciitis, calcific tendinitis, and chronic lateral epicondylitis, expanding nonsurgical options alongside the musculoskeletal care network that includes La Costa Chiropractic & Wellness in the La Costa area. Fluoroscopic and ultrasound-guided injection placement allows concentrated orthobiologic delivery to rotator cuff tears, meniscal lesions, and lumbar facet joints at sub-millimeter accuracy.
