Our Story
Our Story
We have been providing excellent state-of-the-art OBGYN care in the East Bay since 1978, when Bud Rotermund and Lu Hughes joined their practices to form Muir OB GYN. The same goal of compassionate care delivered in a personal way with the top priority being the well being our patients has been maintained throughout the years.
We are proud to be the area’s most enduring group practice. Our doctors and nurse practitioners are among the most accomplished and experienced in the East Bay.
Drs. L. Sandy Hughes (son of the founder of our group), Gerald Katz, and Nadine Hanna have over 60 years of combined experience in the field of Obstetrics and Gynecology. We have delivered thousands of babies, yet each birth is a unique and fulfilling experience. We understand that we have the distinct privilege of being involved in this significant and exciting time in a couple’s life.
We strive to be at the forefront of our field, bringing the most technologically advanced methods of care to all our patients, including Robotic assisted surgical procedures as well as minimally invasive laparoscopic and hysteroscopic procedures. We provide extensive in-office procedures as well, including hysteroscopy, endometrial ablation, and treatment of cervical dysplasia and abnormal uterine bleeding. We provide in office ultrasound evaluation to reduce time required to diagnose and treat most OB GYN problems.
