Dr. Joel Cherdack has a way of describing stem cell therapy that strips away the clinical jargon and gets to the point quickly: "The beauty of it is in its simplicity. You are not introducing a foreign substance into the body. You are concentrating and redirecting the body's own healing components to a place where they are needed." That framing — precise, unhurried, and grounded in a deep respect for what the human body is already capable of — tells you something essential about how Cherdack practices medicine. As the founder of Denver Regenerative Medicine, a clinic he established in 2015 with an A+ BBB rating and a five-star patient reputation, he has spent the better part of a decade making the case that for most people living with arthritis, joint pain, and degenerative conditions, the body's own biology — properly concentrated, precisely delivered — is a more powerful tool than the surgical interventions that orthopedic medicine has long treated as the default answer.
That case is no longer a fringe position. Regenerative medicine has moved steadily from the margins of clinical practice toward the mainstream, and the evidence base for biologic therapies — platelet-rich plasma, bone marrow aspirate concentrate, stem cell applications — has grown considerably over the past decade. What has not kept pace is the quality of delivery. As the field has expanded, so has the range of practitioners offering these therapies, and the gap between a rigorously administered regenerative protocol and a loosely applied one is not small. It shows up in outcomes. Cherdack built Denver Regenerative Medicine on the premise that the therapy is only as good as the physician behind it — and that premise shapes every clinical decision his practice makes.
For Denver residents who have been searching for stem cell therapy options and are trying to understand what separates legitimate clinical practice from the noise, here is a closer look at how Dr. Cherdack approaches this work — and what anyone considering these therapies needs to know before they commit to a course of treatment.
What Stem Cell Therapy Actually Does — And Why Delivery Is Everything
"First and foremost, do no harm," Cherdack says. It is the oldest principle in medicine, and in his practice it is not a platitude — it is the filter through which every treatment recommendation passes. Before a patient at Denver Regenerative Medicine is offered any biologic therapy, the question Cherdack asks is not whether the procedure can be performed. It is whether it is the right choice for this patient, at this stage of their condition, given what they stand to gain and what they stand to risk.
Stem cell therapy, in its clinical application, works by introducing a concentrated population of regenerative cells — most commonly derived from the patient's own bone marrow through a process called bone marrow aspirate concentrate, or BMAC — into damaged or degenerated tissue. These cells carry a demonstrated capacity to modulate inflammation, stimulate the repair of cartilage and connective tissue, and create the biological conditions under which the body can begin to restore function that has been compromised by injury or disease. The mechanism is not magic. It is biology — the same biology that heals a cut or knits a broken bone, applied with clinical precision to tissues that have lost their ability to repair themselves spontaneously.
What makes the difference between a stem cell treatment that works and one that does not is not the concept. It is the execution. Cherdack is unequivocal on a point that many practitioners in the growing regenerative medicine space prefer to gloss over: blind injections — procedures performed without real-time imaging guidance — are a clinical failure. At Denver Regenerative Medicine, every injection is image-guided, using ultrasound or fluoroscopy to confirm exact needle placement before any biologic material is introduced. The target tissue is not estimated. It is visualized, in real time, by the physician performing the procedure. That distinction is the difference between a treatment with a genuine chance of producing the intended result and one that is, at best, approximate.
The clinic's biologic protocols extend beyond stem cell applications alone. Platelet-rich plasma, or PRP, concentrates the growth factors found in the patient's own blood and delivers them to damaged tendons, ligaments, and joint cartilage — initiating and accelerating the natural repair process at the cellular level. BMAC draws from the patient's own bone marrow to harvest mesenchymal stem cells alongside a concentrated mix of regenerative growth factors. These therapies are not interchangeable — the right protocol depends on the specific condition, the stage of degeneration, and the patient's individual physiology — and Cherdack's practice treats the selection of the appropriate biologic as a clinical decision, not a menu choice.
What Denver Patients Need to Understand About Stem Cell Therapy in a High-Altitude City
Denver's elevation — more than 5,000 feet above sea level — creates physiological conditions that most regenerative medicine practitioners do not account for, because most regenerative medicine practitioners do not practice here. At altitude, oxygen availability is reduced, a state known as hypoxia, and the synovial fluid that lubricates joints tends to be thinner due to lower ambient humidity. Both of these conditions affect how tissue heals, how inflammation behaves, and how biologic therapies perform once they are introduced into the body.
Denver Regenerative Medicine has developed altitude-specific protocols that reflect a genuine clinical engagement with these conditions — an approach that matters in ways that are easy to underestimate. A regenerative protocol calibrated for sea-level physiology may not perform identically in a patient whose body has adapted to high-altitude living. The concentration of the biologic, the timing of the treatment relative to the patient's activity level, and the post-procedure management of the healing environment all require adjustment for the specific context of a Denver patient. Cherdack's practice has built that adjustment into its standard of care.
The city's population adds another layer of clinical complexity. Denver's residents are among the most physically active in the country — skiers, trail runners, cyclists, climbers — and the injuries and degenerative conditions that accumulate over decades of that kind of activity present differently than the same diagnoses in a more sedentary population. Cherdack describes his practice's orientation as a "slope-to-screen" focus: a recognition that his patients are not simply trying to reduce pain, they are trying to get back to the mountain, the trail, the bike path. That goal shapes how treatment success is defined, how protocols are designed, and how Cherdack talks to patients about what realistic recovery looks like for someone whose baseline is an active life rather than a sedentary one.
The conditions the clinic treats span the full range of what an active Denver life produces over time: knee arthritis from mild to bone-on-bone, rotator cuff tears, labral damage in the hip and shoulder, back pain, tennis elbow, ligament sprains, and the kind of cumulative joint degeneration that builds quietly for years before it becomes impossible to ignore. For many of these patients, the conventional medical pathway has already been attempted — the cortisone injections, the physical therapy, the recommendation for total joint replacement. Cherdack's practice exists precisely for those patients: the ones who are not ready to accept that surgery is the only remaining option, and who are looking for a physician who takes that position seriously.
What to Ask Any Clinic Offering Stem Cell Therapy in Denver
The regenerative medicine market in Denver, as in most major cities, ranges from rigorously run clinical practices to wellness centers offering biologic therapies with little of the scientific discipline those therapies require to work. A few questions will tell you a great deal about where any given provider falls on that spectrum.
Ask whether injections are image-guided — and ask specifically what imaging modality is used. Ultrasound and fluoroscopy allow real-time confirmation of needle placement before any biologic is introduced. A provider who cannot answer this question clearly, or who performs blind injections as a matter of routine, is accepting an avoidable margin of error in a procedure where precision is the entire point.
Ask about the source and concentration of the biologic being used. Not all stem cell preparations are equivalent. The concentration of regenerative cells, the processing method, and the activation protocol all affect the therapeutic potential of the final product. A physician who cannot speak specifically to these variables — who offers a generic description of "stem cells" without clinical detail — is one who may not have the depth of knowledge to optimize the treatment for your specific condition.
Ask whether the physician has experience treating your specific diagnosis. Stem cell therapy for knee osteoarthritis requires different clinical thinking than stem cell therapy for a rotator cuff tear or a lumbar ligament injury. The physician's depth of experience with your particular anatomy and condition is a meaningful predictor of how well the treatment will be designed and executed.

Finally, ask for an honest assessment of whether you are a good candidate. The most important thing a physician can tell you is sometimes that a therapy is not the right fit for your situation. A practice that presents regenerative therapy as the answer for every patient is not practicing medicine — it is selling a service. Dr. Cherdack's approach is built on the opposite premise: that the right treatment for the right patient produces the right outcome, and that honest clinical judgment is the foundation of both.
A Decade of Doing This the Right Way
Dr. Joel Cherdack did not build Denver Regenerative Medicine by following the path of least resistance. He built it by insisting on a standard of care that many practitioners in this space have not adopted — image-guided delivery, high-concentration biologic protocols, altitude-adjusted treatment design, and a patient-first philosophy that begins with "do no harm" and works forward from there. A decade into that work, the practice's reputation reflects it: five-star patient reviews, an A+ BBB rating, and a growing community of Denver patients who came in facing surgery and left with a different understanding of what was possible.
The clinic's founding mission — to help patients avoid unnecessary surgeries and find lasting relief through the body's own healing power — has not changed since 2015. What has changed is the evidence base that supports it, the sophistication of the protocols the clinic applies, and the number of Denver residents who have experienced firsthand what a well-executed regenerative treatment can do for a body that conventional medicine had written off as a surgical candidate.
For anyone in Denver who is living with chronic pain, facing a joint replacement recommendation, or simply trying to understand whether stem cell therapy is a legitimate option for their situation, the first step is a conversation with a physician who has spent a decade answering exactly that question. The consultation is where it starts — and for many patients, it is where the path to surgery ends.
