Nathaniel Klein, MD

Junior Fellow and Provider

Dr. Klein grew up in a small country town in Michigan before attending Michigan State University, where he double majored in human physiology and nutrition. He then continued his education at Rosalind Franklin University of Medicine and Science, where he received his Master of Science in Biomedical Sciences and a research certificate for clinical sciences.

He strives to make his patients feel comfortable and well-cared for and believes that the best way to do that is to listen to patients’ concerns or worries so they can work together to find a personalized treatment plan. In addition to his fellowship, Dr. Klein is pursuing a Master of Business Administration at the University of Nevada, Las Vegas Lee Business School.
