Originally from the Chicago-land area, Dr. Efren Caballes joined Cornerstone Orthopedics & Sports Medicine in 2016. His approach to patient care is based on combining all available modalities for musculoskeletal conditions including exercise, physical modalities, bracing, injections, and regenerative medicine. One of his special interests is diagnostic and therapeutic use of musculoskeletal ultrasound. His clinical repertoire of treatments focuses on continually balancing the patient’s physical goals with optimal recovery needs.

Prior to working at Cornerstone Orthopedics, Dr. Caballes earned a Bachelor of Science Degree in Molecular Cellular Biology from the University of Illinois at Urbana-Champaign and attended medical school at the Touro College of Osteopathic Medicine in New York City (NYC). Dr. Caballes completed his residency in Physical Medicine and Rehabilitation (PM&R) at New York University (NYU) Medical Center, where he also served as Chief Resident, and completed a PM&R Sports Medicine Fellowship at NYU. His training also provided him the opportunity to take care of the numerous endurance athletes at the NYU Center for Musculoskeletal Care Running Performance Lab, as well as musicians and dancers at the Julliard School and Harkness Center for Dance Injuries.

Dr. Caballes developed an enthusiasm for running while in NYC, where he joined the Prospect Park Track Club and volunteered with Back on My Feet – an organization combating homelessness through the power of running. Since moving to Colorado, he has become actively involved in treating runners and triathletes ranging from recreational athletes to professional and Olympic athletes.

Dr. Caballes is currently certified as a level 1 USA Track and Field coach and was selected to serve as a volunteer physician for the US Olympic and Paralympic Committee Colorado Springs Olympic Training Center in March 2020. Recent and current academic positions include sports ultrasound faculty for the America Medical Society for Sports medicine, clinical instructor for Touro College of Osteopathic Medicine in NY, and clinical instructor for the St. Anthony’s Medical Center Sports Medicine fellowship.

As an avid runner and outdoor enthusiast, Dr. Caballes has completed several marathons in New York City, Chicago, and Berlin to name a few. He also enjoys cross country skiing, cycling, hiking, and traveling/running Ragnar Relay Races with his wife.

I had a PRP procedure done on my shoulders with Dr. Cabellos at the Westminster Cornerstone office. The office is very nice and the front desk staff are all professional and pleasant to talk to. After many months of physical therapy with Cornerstone. I decided to try the PRP procedure, because I felt like I couldn’t quite get over the hump to full recovery with PT alone. During my initial evaluation and ultrasound with Dr Cabellas, he explained my condition and what PRP might be able to do for me. He was very thorough without being pushy. I decided to go forward with the procedure and just had it done. Dr Cabellas and his assistant were good to work with and made sure I was comfortable. I’m happy with my experience so far, but have a few months until we might know how effective the treatment was.

Dr. Caballes is quite literally one of the best medical providers I have ever worked with and he’s already saved my military career (twice!). Extremely thoughtful, always open to answering any and all questions, extremely easy to talk to, and has been incredibly generous with his time by fitting me in for “emergency” appointments right before the holidays. Couldn’t recommend him more!

Dr. Caballes and the staff at OCC are incredible. He took the time to break down a complex ankle sprain into a comprehensive plan and timeline for returning to sport as well as my other hobbies. Taking the time and turning what was originally a daunting MRI into understandable and meaningful data to get back on track and making the whole process less scary than when I walked in. His approach and understanding of athlete recovery is truly next level. Thanks again!

Amazing experience. Came in to get a more detailed look at an injury I had running and he was very clear with me on his recommendation. He was patient with me with all the questions I had and even answered more questions the next day I had as well as referring me to another Dr in the office. Would recommend him to any runner I know with a foot or ankle injury needing an ultrasound.

I’ve been dealing with foot pain for many years after several operations, and maybe always chasing a the problem, when missing the real cause..? Even after MRI results and Dr analysis of course going along with the MRI report. I’m sorry to say…it took a chiropractor’s review of the same MRI to suggest I had Baxter Neuropathy. I felt Dr didn’t believe with a chiropractor and was reluctant to read the report fully due time.? But I thought it would be worth Dr giving me a test shot to see…IT did wonders and now we may have the root cause to my unknown misery past 6 years starting with Plantar fasciitis.

Dr Caballes was kind and listened to my concerns, helping me to understand where my pain was radiating from and why. We agreed on localized injections to alleviate my pain and 2 days in I’ve felt so much relief already!! He has steady hands and talked me through it so I knew what to expect for each injection into my shoulder. I’m grateful for his care and I highly recommend him and his medical assistant Megan at OCC.
