Glenn A. Mackin

Glenn A. Mackin, M.D., 64, of Center Valley, passed away peacefully on Tuesday, December 25, 2018 surrounded by his loving wife and daughters. Born in Philadelphia, Glenn was the son of Alexander and Evelyn (Manbeck) Mackin. He shared 24 years of marriage with his wife Lynn Posbergh. Glenn was a neurologist at Lehigh Valley Health Network for the past 20 years, after originally working at the University of Colorado Health Sciences Center in Denver. After graduating from Haverford College in 1976 with a degree in political science and minor in American history, he attended NYU law school for a year before deciding medicine was his true calling. He graduated from Jefferson Medical College in 1983, and became certified in internal medicine after a residency at Evanston Hospital, in Evanston, IL. He then completed a residency at Boston City Hospital in neurology, followed by a fellowship in multiple sclerosis at Brigham and Women's Hospital and a fellowship in neuromuscular diseases & EMG at University of Pennsylvania. Glenn served for many years as an officer of the American Academy of Neurology, which was a great source of professional satisfaction. He founded the ALS clinic at Lehigh Valley Health Network 15 years ago, and was recently recognized by the ALS association Greater Philadelphia Chapter for his achievements in the field of ALS. His heart and soul as a physician was providing compassionate, direct patient care, as well as working with esteemed members of the ALS multidisciplinary clinic team to improve the lives of patients with Lou Gehrig's disease. Glenn's interests in history and politics continued throughout his life. He enjoyed gardening, keeping the backyard birds well fed, traveling extensively with his family, and summer vacations in Barnegat Light, NJ.. Nothing gave him greater joy than spending time with his wife and daughters.
