Current MIS Fellows

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.

Dr. Klein then went on to obtain his medical degree from the Chicago Medical School, completing his OB/GYN residency at St. Joseph Hospital in Chicago. While in residency, he served as the chief resident as well as the administrative chief.

During his residency, Dr. Klein helped develop a new GYN training curriculum with an emphasis on simulation training regarding robotic and laparoscopic surgical techniques while integrating the latest minimally invasive surgery research. He developed a passion for treating patients with chronic pelvic pain, especially related to endometriosis, as he found this patient population to be dramatically underserved and often times inadequately managed.

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.

When he is not in clinic, Dr. Klein enjoys doing all things outdoors and eating good food. He is licensed in Nevada, California, and Washington.
