About Me

For over 30 years, helping patients with metabolic bones diseases (osteoporosis and Paget’s disease of bone) and other disorders of mineral metabolism (vitamin D deficiency and hyperparathyroidism) has been one of the most rewarding parts of my career as a physician. I enjoy helping patients with complicated problems find ways to treat their disease. I have many patients that I have followed for 10 to 20 years, and I highly value the relationship we develop. We now have FDA-approved therapies to treat and prevent fractures in osteoporosis, and reduce pain and disability in Paget’s disease, so it is even more rewarding to help patients decide which treatments are best for them.

Clinical Focus and Research

My Research Interests

I design and conduct clinical trials for the diseases that I see regularly in my clinic, principally osteoporosis and Paget's disease of bone. Several of these trials have resulted in new drugs being approved by the FDA. This is why I love to see new and old patients. Together, we learn ways to help and hopefully solve some of their problems.
