Alexander A. Clerk, M.D.
My goal is to provide the highest level of evidence-based care to promote the safety, welfare, and well-being of my patients and to provide specialist support to their primary-care physicians.
I believe in personal, patient-centered care, in which patients take an active role in their health and health care.
I pride myself on taking time to explain things thoroughly so patients can easily understand and comply with their treatment.
I have found that the treatment of sleep disorders is particularly gratifying because of the vast improvement in the quality of life that many patients experience.
