About Riverwalk OB-Gyn

In 1979 Tristan Castaneda, MD started with a simple premise: Make available to every woman the health resources she needs to live a healthy, active, and long life. At the same time, educate each woman about the importance of preventative health measures. This same idea still drives us today, some 30 years later. The track record we’ve accumulated over the years speaks to our commitment to patients, their families, and the community at large. Both our medical and office staffs are second to none, who genuinely take an interest in individual patient’s needs. We think you’ll notice the difference immediately when you step foot inside our doors. We’d love to see you today to map out a health and wellness plan that’s tailored to your health history and needs.
