They are a committed group of physicians that are proficient in high-risk obstetrics, menopausal issues, screening for breast cancer, treatment of abnormal pap smears and communicable diseases, open gynecologic and laparoscopic surgery including the DaVinci Robot, reproductive endocrinology, infertility, osteoporosis and urogynecology. In addition, they also offer bone density screening and diagnostic ultrasound in their office.
“Women's Medical has chosen to become part of Prima Medical Group because we have had a long-standing relationship with Prima physicians in the primary care arena and at Marin General Hospital,” says Dr. Voss and Dr. Matsik. “Prima shares our vision for a strong physician association in Marin, supporting both our local hospitals and our community”.
“The expansion of Prima Medical Group supports continued community access to high quality, local physicians & services.” commented Joel Criste, Prima Medical Group’s Chief Executive. “Adding these excellent physicians to Prima enhances continuity of service within Prima while strengthening the entire medical community”.
