Dr. Cohen is a board certified emergency physician working in the busiest emergency department in Colorado with over 100,000 visits a year. He has been a Complete Health Improvement Program (CHIP) facilitator for 7 years. Dr. Cohen himself was a three vessel coronary bypass graft recipient in 2003. Treating the sickest of the sick, and the drunkest of the drunk, in a busy emergency department makes for a stressful environment.
