DISC’s honorees include top doctors across spine, orthopedics, pain management and vascular surgery.
At DISC Sports & Spine Center, excellence in patient care isn’t just a goal, it’s a standard. This year, 20 of DISC’s physicians are being honored with the prestigious title of Southern California Super Doctors. Recognized across a range of specialties, including spine surgery, orthopedics, pain management, and vascular surgery, our world-class physicians are acknowledged for their exceptional contributions to the field and their unwavering commitment to patient care.
The Southern California Super Doctors list identifies top doctors by following a rigorous, multi-phase selection process that combines a survey, independent evaluation and peer review, among other qualifying measures. Only physicians who have attained a high degree of peer recognition or professional achievement can be selected — in fact, only about 5% of active physicians in the region are given this esteemed honor. A special category, "Rising Stars," is reserved for those in practice for 10 years or less, highlighting their emerging impact on the medical community.
This year, DISC is proud to see 20 of its physicians across various specialties earn this recognition. These honorees have set themselves apart not only for their clinical expertise but also for their dedication to advancing patient care through innovation, collaboration, and a commitment to excellence.
