Training Opportunities

Resident Education

Minimally invasive surgery is a relatively new field of surgery, with rapid and continuing technological advances and the emergence of a new generation of MIS surgeons. The goal of this rotation is for the resident to understand that achieving and maintaining excellence in surgery is a continuing lifelong endeavor, requiring adaption to new and changing technology, and continued practice and training.

Harbor-UCLA Residency Program

Third- and fourth-year residents from Harbor-UCLA rotate through the LVMIS and Women’s Pelvic Health Center program for five weeks. This immersion program is designed to advance gynecology training in minimally invasive surgery by participating in the one-on-one mentorship program with master laparoscopists specially trained in MIS gynecology surgery under the direction of Dr. K. Warren Volker.

University of Nevada School of Medicine Residency Program

Third and Fourth year Residents from the University of Nevada School of Medicine rotate through the LVMIS Minimally Invasive and Women’s Pelvic Health Center Program for 4 weeks. This program is designed to advance gynecology training in Minimally Invasive Surgery (MIS) by participating in one-on-one mentorship program with “master laparoscopists” specially trained in MIS gynecology surgery under the direction of Dr. K. Warren Volker.

Visiting Residents

Fourth-year residents from select residency programs rotate through the LVMIS and Women’s Pelvic Health Center program (rotation time may vary). These individuals are expected to have an interest in future fellowship training. Visiting residents are trained on specific minimally invasive surgeries, on a case-by-case basis. Assessment of surgical skill level is assessed at the beginning of the rotation. Deficits are identified and corrected during their time at LVMIS-WPHC. Residents will participate in a one-on-one mentorship with master laparoscopists specially trained in advanced MIS surgical techniques under the direction of Dr. K. Warren Volker.

While completing her medical training at the University of Cincinnati in Ohio, she spent a year abroad in Central America working on a maternal health education project, which ignited her interest in international health. She then returned to California to finish her OB/GYN residency at University of California Irvine.

Dr. Sisto considers women's healthcare her passion and has always been interested in women's global health, focusing on underserved communities. She has worked in Nicaragua, Honduras, Ecuador, and Tanzania, and plans to continue to fight for all women's access to healthcare around the world.

Junior Fellow - Nathaniel Klein, MD

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.
