Overall was super good visit

Some of the doctors I usually see are booked up to 4 or months- my family can't get in to dermatology or other specialties or general providers. There was never a wait before- lately it's a problem. Dr Diaz is not an issue because I plan for routine checkups.

Dr Diaz is excellent doctor she explained my concern very well .Thanks to her

All very well

Dr. Diaz is a very skilled doctor. She is always well prepared and ready to answer any questions and give clear directions.

The best care always

Dr. Diaz wore a disgusting dirty mask that kept falling off her mouth. Old thinking doctor. I refuse to see her again and will request all endocrinology concerns to my GP or take to a Integrative or Functional doctor

I had a very good appointment , she has a knowledge of my health problem

Only good experiences with Dr. Diaz.Love her. She's very kind.

Dr Diaz is very good at what she does! She is very knowledgeable and answered all my questions and concerns. She also takes the time to listen!

Good

Dr is apathetic. I gad major surgery in July. Have seen this provider twice since surgery. Not once has she asked how I'm doing since my surgery. Just looks at the labs, checks the boxes, refills/adjusts Rx and send me on my way. No compassion, no suggestions just follows the script.

Always good experiences.

Excellent care.

In regards to my medical visits with Dr. Diaz, I have nothing but gratitude and praise for her professionalism and the excellent care that I always receive whenever I have appointments with her. She listens intently to my concerns and with her, I feel that we actually work together as a team to come to whatever treatment plan works best for my health. Dr. Diaz comes across as as emphatic, honestly, respectful, intelligent and highly professional. She is a gem!

Honestly speaking, Dr. Diaz always has demonstrated her concern for my well being, I'm thankful that I'm not treated like a number she is genuinely concerned about my thyroid condition and diabetes getting under control.. So thankful that I have a doctor who cares

Dr. Diazwas incredibly kind and attentive, and made me feel at ease," and "She explained every step of the treatment plan clearly and her staff followed up afterward".

Dr Diaz provides excellent care and listens to my concerns and explains everything

This care provider has determined that my medical situation has improved to the extent that I should be followed by my PCP and no longer need to be followed by her.

I am very pleased with the time she spent with me and when above and beyond more than what other doctors have done in the past. He was very difficult to get an appointment so I had to wait a little bit longer, but it was worth the wait.

Dr Diaz is very knowledgeable and thorough in my medical conditions and in updating my treatment plan.

Dr Diaz is such a sweet doctor. She listens, and goes into detail what is it that I should or should not do. She's caring and not quick to just prescribe medicine . Orders the test when needed too.

Dr Diaz is "on top of her game".

Dr Diaz went out of her way to make sure all necessary medical information was obtained and provided to the surgeon to allow him to do his job.

Excellent provide, very thorough and knowledgeable!

Dr. Diaz paid attention to all medications I'm taking and gave advice the doses of the medication I should take.

The doctor is knowledgeable & very approachable. I trust her & that is so important

I recently had surgery at SJO and had to reschedule my endo appt. I called the office & spoke to the medical asst and specifically asked her to tell the doctor that I had surgery and to please be familiar with my condition. At my appt a week later she had no clue about the surgery and failed to update herself while we were talking.
