Emeritus Professor of Medicine Geisel School of Medicine at Dartmouth Director Respir Services Valley Regional Hospital. As a pulmonary physician at Dartmouth-Hitchcock Medical Center in Lebanon, NH, for 32 years, I provided out-patient and in-patient consultations, taught medical students, residents, and fellows, and performed clinical research in COPD. Presently, I am Emeritus Professor of Medicine at Geisel School of Medicine at Dartmouth in Hanover, NH, and work at Valley Regional Hospital in Claremont, NH, where I am Director of Respiratory Services. The website - donaldmahler.com.- provides practical and current information that positively affects the lives of those with COPD and their families. In addition, I have written a book entitled, "COPD: Answers to Your Questions" based on the most frequent questions that I have been asked by patients and their families. This self-published book with 111 pages will be available on Amazon.com and BarnesNoble in January 2015.
