"Dr. William (Bill) Brown is a superb writer, reflected in his long list of scientific publications in the medical literature and having taught many young investigators in his research program how to write. I was one of those investigators and attest to Dr. Brown’s ability to succinctly, clearly and accurately report his research findings." Phillip D. Smith, M.D. Mary J.
