    Mitzilene A. Tuazon has been my primary care doctor for many years. She is my favorite doctor and is always upbeat and happy. She reviews my record before I see her and she is knowledgeable about any medical events that happened since I saw her last. She has given me excellent advice on how to care for my dry eyes. She was concerned about me when I had a pacemaker surgery. She has worked with me with my asthma and bronchitis problems. She encourages me to continue with my water aerobics and to keep active. She is a great doctor!

    She's an extremely bright, caring doctor that I have been seeing for many years. However, during this last visit, for the very first time ever, I felt that she was suspicious of my need for medical leave. That was disturbingly hurtful. I don't make things up. No I don't get paid from work when I am on medical leave. No my family is not here on vacation and I just want to spend time with them. I am genuinely in in severe medical and emotional distress. She did accommodate the request, for which I am extremely grateful, but I left feeling like she thought I was trying to pull one over on her. I would never do that. I respect her far too highly.

    Dr. Tuazon is very professional, caring, respectful, detailed as to what my blood draw showed. She asked if I had any health issues if any to talk to her about. Just so detailed and easy to talk to.
