About Me

Hello, and welcome to my Web page. I am Dr. Ontiveros and I am happy to be of service.


I grew up in Santa Ana in Orange County. I have always enjoyed helping people, so becoming a doctor was a perfect fit. I am also fascinated by the art and science of medicine.

About my practice

Kaiser Permanente has a very rich and diverse mix of members. I am pleased to say that our doctors and nurses represent this diversity well. Therefore, we are able to deliver a very personalized level of care to all our members.

How I thrive

It's very important to keep a healthy balance between work and home. I love spending quality time with my family and friends. I enjoy keeping fit at the gym. Our downtown music center is one of my favorite places to visit. I also enjoy traveling around the world.
