We’re here for you during the COVID-19 crisis

Colorado Center for Arthritis and Osteoporosis remains open and ready to provide you with outstanding medical care for your arthritis, autoimmune and bone health needs during this difficult time. All of our providers are available via an easy-to-use and secure video chat platform called telehealth, accessible through your phone or computer. Telehealth services are available to patients that are new to our practice, as well as our established patients. We can provide medical care via telehealth to residents throughout Colorado. We are also able to serve residents of other states during this public health emergency.

Some medical needs require in-person care, such as for a procedure, medication administration or to evaluate an urgent problem. All five of our locations are open and available for in-person visits to patients who need them.

About CCAO

Since 1998, the rheumatologists at Colorado Center for Arthritis and Osteoporosis have relieved the suffering and improved the quality of life of tens of thousands of patients with conditions affecting the bones, joints, connective tissue and immune system. Some of these conditions include rheumatoid arthritis, osteoarthritis, psoriatic arthritis, ankylosing spondylitis, lupus, vasculitis, Sjögren’s syndrome, gout, fibromyalgia and osteoporosis. We combine the latest advances in medical knowledge with a compassionate, collaborative, patient-centered approach to develop a treatment plan that allows our patients to achieve their goals, maximize function, and minimize chronic pain and disability.

Many of the new medications developed to treat various forms of arthritis, autoimmune disease, and osteoporosis are delivered by intravenous infusion. We have an infusion center in each of our offices in order to administer these medications in the most efficient, comfortable, and convenient manner possible.

CCAO has five convenient locations: Northglenn, Longmont, Boulder, Broomfield and Wheat Ridge. Our providers will perform a thorough evaluation at a time and location that is convenient for you. Talk to your primary care provider about a referral to Colorado Center for Arthritis and Osteoporosis. Or if you prefer, just give us a call. See whether an evaluation by one of CCAO’s rheumatologists is right for you.
