    My visit with Dr. was excellent. He answered all of my questions. I was very impressed with the level of knowledge that he had about my past examinations and his level of interpretation of the imaging studies that were made. In my book, Dr. Santiago Lozano Calderon is just one of the premium top-notch providers out there. I would not hesitate to see him again and trust him implicitly.

    I used the portal to ask a follow-up question, actually two follow-up questions, but I'm still waiting for a return call from someone on staff there. So I think it would be great to have faster follow-up to questions through the portal.
