Dr. Jocelyn Ivie

Our board-certified OBGYN, Dr. Jocelyn Ivie, has found nothing that can compete with the joy that is felt after delivering a baby. Her career as an OBGYN has helped her develop several other professional passions along the way, such as finding solutions for women with sexual dysfunction, performing minimally invasive surgery that includes robotic and single-site procedures, and vulvar cosmetic surgery. Dr. Ivie is board certified through the American Board of Obstetrics and Gynecology, and a fellow of the American College of Obstetricians and Gynecologists (ACOG). As an award-winning OBGYN, she was awarded the "Best Doctors Award" in 2015 and 2017 by Desert Companion Magazine. Dr. Ivie lives by the mantra, "Be present in the moment." She wants you to know that once the exam room door closes, she will shut out whatever is happening on the other side.

Dr. Ivie is committed to helping you navigate the trials and tribulations of being female - from adolescence to menopause. Dr. Ivie grew up in southern California in a very tight-knit Filipino family. She received a biomechanical engineering degree at Cal (UC Berkeley). Then, she took a six-month break during college to work at a biotech firm. Dr. Ivie soon realized the doctors at the biotech firm had more fun than the engineers. She switched gears and went to medical school at USC Keck School of Medicine in East Los Angeles, CA. She stayed in the area for her OBGYN residency at White Memorial Medical Center.

After separating from the Air Force as a major, Dr. Brill had always planned on moving back to the East Coast. However, the malpractice crisis in 2002 found south Nevada with a scarcity of physicians, all while the population was expanding like never before. Dr. Brill decided to stay in Las Vegas and has been in private practice since 2003. Listening is probably the one skill that Dr. Brill cherishes most, especially when it comes to listening to his patients, as well as his wife and three children.

Today, they have three wonderful children, and just like his job of delivering babies, they keep him busy at all hours. In whatever spare time he can find, Dr. Brill is an avid tennis player, SCUBA diver, and proud hockey and lacrosse dad.
