My only problem was that the Dr., said to call if the condition persisted which it did and he would call in a prescription. Upon call I was told it would take up to 72 hours for them to order the script. I find this really unacceptable and the assistant was to call me back and she never did

Wonderful doctor who put me at ease! I would recommend him to anyone needing ob/gyn care.

Good experience.

Dr. Chaves is such a caring doctor. You has been my doctor for many years. I have recommended him to others and will continue to do so. He takes the time I need to answer my questions and to actually examine me. He is friendly, and while I know he is a very busy doctor, he does not make me feel rushed. I appreciate that! He is a great doctor!

Was very quick with me. I had questions and concerns about a certain medication that I had brought up with the MA and the doctor didn't even bring up the topic...he was about to leave the room and I had to bring it up. Still don't feel like I have made an informed decision due to the lack of guidance by the doctor.

Happy to finally have an OB who listens and cares!

Only dislike I had about him was I waited longer in my room than the time he was in it . And then he got a phone call on his cell and took it and walked out the room .

Dr was kind and listened.

Discussion was a little frustrating. I had previously been led to understand that I may be able to return to work when I was ready, when this discussion was brought up this was not the case. It was very frustrating as I have no other income and would not ask to return to work if I wasn't ready and none of this was considered at this time.

Dr. Chavez is a class act. He is very kind and made me feel very comfortable. His bed side manner is exceptional and he lightened the entire experience through this upbeat and kind demeanor. Memorial Healthcare is lucky to have him! Hopefully they appreciate all he brings to the table.

As soon as Dr Chaves walked in he says oh your having this issue go see this specialist. Didn't try to say let's check hormone levels let's do this that etc. Within a min of him being in room was handing me a flyer

Dr Chaves has been my ob/gyn for a long time. He always listens to my concerns and explains everything well.

It's taken me 12 years to get a doctor who would respect my desire to not have children and provide the care I needed to make that decision permanent. Thank you *Dr. Smith & *Dr. Chaves!
