Board Certified OB-GYN

Dr. Nader Abdelsayed, MD

Dr. Nader Abdelsayed, affectionately known by his patients as Dr. Nader has been serving the Las Vegas Community since 1996.

He strongly believed that he was able to serve his community with more dignity and respect than the large, impersonal, corporate-owned practices in town: so he set out to establish Dr Nader and Associates.

“Patients deserve to be treated with dignity and respect regardless of ethnicity, race, or economic challenges.” he says with earnestness to whoever chooses to listen.

Born in Cairo Egypt, he immigrated to the US as a child, with his hard working parents and two brothers. He inherited their work ethic and their drive to help others. “ After all is said and done; all you have left is your legacy, and those you've helped along the way.”

He began his college career at UCLA, then attended medical school at USC. He then completed his OB/GYN training at the White Memorial Medical Center. Though the studies of Science and Technology drive him; he has learned through experience that his patients teach him his most valued lessons every day. Dr. Nader received his Masters Degree from Cal State LA in Psychology and Marriage and Family Counseling. As a lifelong learner, he has earned certification in Acupuncture, studied Nutrition, and continues to explore naturopathic practices.

He lives with his lovely wife of 35 years. He enjoys traveling, reading, and cooking for his kids and grandkids.

When Dr. Wang is not working, she likes to relax by doing small projects such as gardening, art/crafts, or learning to cook new dishes.

Dr. Wang’s journey as an OBGYN started when she witnessed her first delivery as a medical student. She was completely fascinated by the process and overwhelmed by the amazing emotional experience that is shared with the mother and all the family involved. Dr. Wang knew then that she wanted to learn more and spend her life helping people with these powerful but also vulnerable moments. Since then she has also developed a strong passion in many aspects of women's health and caring for patients at every stage of their life. Dr. Wang is committed to evidence-based care and empowering patients with all the information they need to live a healthier lifestyle.
