The wait time was long and I see that on multiple accounts but after my time with her now I know why. She takes her time with her patients and really listens to understand. Offices with short wait times my timewith the Dr. is rushed I get pills thrown at me and pushed out the door. Hence why after 27 years o life I’m going to the Dr for the same issues. I’m confident Dr. Ana will finally cure me.

I’m so happy I finally found a caring doctor who takes time to listen, analyze, & explain everything! I am very picky on doctors, as the majority of my experience is negative, with them rushing out the door, but Dr. AnaSierra De Aragon is completely different. She is very kind and helpful, & so is the nurse practitioner. I would highly recommend this practice to anyone!

Dr Aragon is a very respectful and listening doctor, as are her staff. I usually never go to the doctor, cause I am not a fan and never felt like they take the time to listen to understand, Dr Aragon mademy first dr appointment in years, and my first one alone as an adult very easy and enjoyable. Thank you!

I am almost 61. I've seen a lot of Doctors, and met a lot of office staff!!! Dr. Aragon and her team are not just professional and thorough, they are down to earth and made me feel like I was sittingwith a couple of old buddies discussing my recent (hospital fail) in Las Vegas...I will most definitely stay with her the rest of my days and refer her to everyone I know...I went to get a referral to my cardiologist, and left there knowing so much more about my health.....??????????double stars for her and team!!!!!

I loved the doctor, hated the front desk. I booked my appointment, even got a confirmation call and everything. I came in for my appointment and they didn't have me on their schedule at all, not even for another day.She juststarred at me like I was stupid, she finally had it click in her head that I wasn't going to leave so she then decided to get me in for an appointment I just had to wait over an hour. Not only did they not have my appointment they didn't receive my online forms either so I had to fill that out again. I also took a test for them which they told me I would receive results in the next couple of days which I still have not heard anything back from when I was there which was over a month ago now. So I decided to call, and guess what? They claimed I never took the test. They don't know what they are doing here and I would not come back again nor refer anyone to here.

In three words: it was great! Based on my first visit I have a feeling Dr Aragon will become our family doctor. The virtue I saw in her, I haven't seen in a doctor for a long time and that is that she really cares.

Having a timer ring when your time is up, is rude in mu opinion. It tells the patient that whatever you are there for is not important enough to finished talking. Once again her staff made a mistake with one ofmy referrals and it's not the first time. Due to that mistake, the insurance at this time is not paying for my first visit that I had already, and today's visit was cancelled due to the same mistake. She seems to depend on her staff without checking to see if what she has them do, has been done and done correctly. I have had trouble with them getting my insurance put in the correct order. They aren't good about returning calls or responding to messages. At this rate, I am seriously considering changing Doctors. A Doctor is only as good as her staff.

I liked the doctor and all, but I don't like the fact that I have to go somewhere to get my blood work done. And only time she touched me was to listen to me breath. I don't know, are doctors not required to touch patients anymore?

I think her herself is ok, I had come it and asked for help with a specific problem which I had to reiterate again after she came in because she started offering me advice on other problems, which while appreciated shouldn'thave been the focus. I was in the office a total of 2 hours and 20 minutes. It was a crazy wait time and for an hour of that I was sitting in the office even though I had filled out most of the paper work the previous day. We were a little late to the appointment, but that is ridiculous! Hopefully next appointment goes better.

Dr. Aragon is a nice, thorough, and knowledgeable Doctor, however her office is not as well run as others I have been to. The wait was extremely long both times I visited, and the waiting room was crowded and almost chaotic.I was given some follow up lab tests to do and I did not feel that the follow up was sufficient. They did not contact me about abnormal results, instead I had to contact them and did not receive a call back initially. I suggest that they improve their timeliness and be more proactive in contacting patients when they have abnormal test results to discuss the next steps.

While the wait may have been a bit excessive, it was worth it. Dr. Aragon was very thorough with here exam . More thorough than my Last Doctor who will not be named here. My main focus is getting control oftype 2 Diabetes. After talking with her and explaining my current meds and what i was doing to control this issue, A plan was made there and then. I was set up for the A1C i need and am over due for, and she suggested a few other procedures that I was never offered by the previous Doctor, which i accepted to have done. Dr Aragon seems to really be into her profession. That I like!! I wanted a Doctor that wants to be a Doctor and I think I have finally found that in Dr Aragon.

Dr. Dr Aragon was fine, but I was disappointed that I never got a call back with the results of the tests she ordered. I called back and left a message but never got a response. Not a huge deal becauseI'm feeling fine now, but would have been nice to have the office call me instead of vice versa.

She was wonderful. However the directions sent by ZocDoc sent me miles in the wrong direction, dropping me off at a vacant lot. Turns out the address is exactly the same in Phoenix as it is in Gilbert. You need tomake sure you have the directions for Gilbert and not Phoenix. Fortunately, they let me reschedule for later in the day so I still was able to seethe Doctor.

The wait was way too long for everything; from the time I walked in to when I finally got my prescription, it took about two hours. There came a point where I had to go out and find someone to assistme! It was as if they had forgotten I was there. Very inconvenient, unprofessional (the receptionist didn't greet me and was on her cellphone), and time consuming. I won't be returning.
