    Dr. Lockwood is insightful, admirably well prepared, exceptional listening skills, in command of the literature and new developments in the field. Went the extra mile in thinking through options for treating my complex variant of osteoporosis. A compassionate and exceptional physician in every respect. I was fortunate to have this appointment with her.
