Dr. Ronquillo always explains what my test results mean and how to improve the areas of concern. He really seams to be interested in my health and takes time to ensure I get the care I need.

Very rude and off putting Doctor. I was in severe pain and hadn’t slept in several days. Dr. Ronquillo did virtually no testing and ordered generic labs and an ultrasound that yielded no evidence as to the pain. The only follow up I received is because I called to see if there were any updates. I sought a second opinion and this doctor made an accurate diagnosis and started treatment immediately. I now have neurological damage in my leg and have to seek out advanced treatment, some if not all of this could have been prevented if Dr. Ronquillo had done his job, he did little to nothing to help me and now I may have permanent damage. Go see someone else!
