Dr. Eric Goralnick, an emergency room doctor at Brigham and Women’s Hospital, was a block away from the marathon when he learned about the bombing.  By the time he arrived at the ER, the staff was already in motion. The hospital’s personnel regularly undergo drills and training for emergency events, and on that fateful day, put all of their practice into play. This year, Dr. Goralnick plans to support the hospital’s team and honor those who were injured in last year’s bombings by running the 2014 Boston Marathon.
