Why Choose Us

We understand that finding out that you or a loved one has a rare bone disorder can be overwhelming. These rare bone disorders, such as Osteogenesis Imperfecta (OI), Hypophosphatasia (HPP), X-linked hypophosphatemic rickets (XLH), Fibrodysplasia Ossificans Progressiva (FOP), or Tumor-Induced Osteomalacia (TIO) and others, are the focus of our program, which provides care across the lifespan from infants to adults. This clinic is unique in that it treats entire families with these lifelong conditions.

Our team is led by knowledgeable physicians and staff who are developing innovative research in order to develop guidelines to treat these ultra-rare and chronic diseases.
