Orange County Urology Associates (OCUA) is vigilantly monitoring and responding to new information about the coronavirus (COVID-19) outbreak. Our top priority is the health and safety of our patients and staff, our community and the public at large. OCUA is following the guidelines provided to us by the Centers for Disease Control (CDC) to protect you and your family. Our offices are open and our doctors and staff are here to provide you with care.

We have boosted our capacity to provide telemedicine visits. We may be calling you to determine if a telemedicine visit would be best for you.

We ask that if you know you have had close contact with a COVID-19 infected person to not come to the office. Rather, please call to discuss your situation and our staff will help determine the best thing to do for you. If you have a fever, cough or have shortness of breath also call the office rather than come in. We are all in this together.
