Ji Won Yoo, MD, is the Nevada Interprofessional Healthy Aging Network Program Director and Assistant Professor in the Department of Internal Medicine at the Kirk Kerkorian School of Medicine at UNLV. Nevada is a very popular place to retire, especially, with the baby boomer generation. At the same time, the number of providers of medical care in Nevada has not kept pace with the overall population and specifically, not with the geriatric population.  For example, Nevada ranks 48th out of 50 states in primary care provider shortage. As we age, care often becomes more complex.
