    My experience was great. Provider had checked my history before he saw me, took care of my issue immediately, made me feel as if he had plenty of time to talk to me.

  • Jul 16, 2019

    He is AWESOME

  • Jul 02, 2019

    I am very fortunate to have such a brilliant doctor. You only get a doctor like this once in your life; if you’re lucky. Dr. Ortega Loayza‘s level of care, passion for his work, extraordinary compassion, genius (yes) and his superlative support staff (especially Ashley), supersedes that of any other doctor I’ve ever seen- and 90%+ of them are outstanding. Dr. Ortega Loayza has dramatically improved my quality of life and I’ll always be deeply grateful to him ad his staff. I cannot say enough positive things about this doctor and his methods of medical practice. He elevates his field.

  • Jun 28, 2019

    Dr. Ortega was super friendly and listened to me and I think I came up with a good plan going forward and I think was one of the better dermatologists I've ever seen. Thank you.

  • Jun 27, 2019

    Dr. Ortega is through and precise in what he looking for on the skin. Good communicator, making things clear and making sure you understand what he is saying. Making clear what the treatment is for you. Never in a rush.

  • May 22, 2019

    Excellent communication, thoughtful and caring person. Listened to my concerns and explained in depth.

  • May 21, 2019

    Perfect care from Dr. Ortega and Ashley.

  • May 12, 2019

    He seemed like he was in a hurry the whole time, he just was very quick. And I felt like it should have been...there was some questions I had, and he didn't quite answer all of them. He kind of brushed by things quickly. I don't know if the day was too busy, or what was going on, but I had some questions left unanswered after the appointment. Thank you.

  • May 09, 2019

    She was great! Very welcoming and I didn't feel embarrassed about bringing up any issues. Some doctors make me feel dumb or like the problems I have are imagined, but she listened well and gave me information very professionally. She's great!

  • May 09, 2019

    The assistant who called me back asked if I took medications. She then proceeded to pull up my medication list and pointed out that I took a lot of medications (as if that isn't obvious). I completed paperwork prior to the appointment that wasn't reviewed. I'm not sure of the point in completing the paperwork. The appointment lasted maybe 20 minutes and I left with information I had already researched on my own.

  • May 09, 2019

    Dr. Alex Ortega Loayza, listened to me, then explained what was going on in a way I could understand. He was patient and understanding. A trait that many Dr's do not have.

  • May 09, 2019

    Very professional, very patient with my son. Highly recommended.

  • May 08, 2019

    Dr. Ortega is always helpful, kind and understanding. He explains things that are happening so I can understand them and tries to make me as comfortable as possible.

  • May 07, 2019

    My visit was memorable. All who I encountered were professional and knowledgeable though I was most impressed by the personal touch I was treated with. The entire team went above to help me and I am grateful for that!

  • Apr 26, 2019

    Dr. Ortega was very kind and thorough, and I felt comfortable with him right away. Luckily I didn't have anything worrisome on my skin, but if I did, I would feel about being under his care. Thank you!

  • Apr 25, 2019

    Always friendly and welcoming, the act as if they are grateful to see me!

  • Apr 25, 2019

    I felt that they did a really good job and they were really trying to make things work for me. I really appreciate it really good.

  • Apr 22, 2019

    Hello, this is [Name] I'm calling about your survey about my doctor. I can't tell you how wonderful this person is, how much he's done for me that doctors around the country could not do, and I have a very rare and strange disease. He not only diagnosed it, but has come up with an amazing treatment plan that will allow me to return to work and be in ... basically have my life back. He did that when other doctors could not. He did it joyfully and professionally and wonderfully and his staff as well. He's surrounded himself with some of the most professional kind and hard working people and I actually look forward to seeing them. I just can't tell you enough what this doctor in particular and I don't care for doctors much but this doctor in particular has literally saved my life.

  • Apr 20, 2019

    Great doctor with a very competent team surrounding him. Always have a good experience when visiting his office.

  • Apr 19, 2019

    Dr. Ortega and his staff -- as usual -- were on-time, fully informed on my history, and prepared to assist me. They listened to my questions and answered them to my satisfaction. The suggestions for my treatment were clearly explained. Empathetic, knowledgeable, skilled. Does not get any better. Thank you.

  • Apr 19, 2019

    Very good

  • Apr 13, 2019

    I think Dr Ortega is brilliant and superior, on this visit there was an incredible resident and another medical student who was great. Sorry didn't get their names.

  • Apr 11, 2019

    It was a quick visit but he was very pleasant

  • Apr 08, 2019

    My first appointment was great. This one had an assistant who was being trained. I cannot say how things came about but my medicine list ended up being confusing so I had to spend time with extra communication to figure out what was meant. Usually it's straight forward. In general I felt this appt was a little unfocused & the summary not as helpful as the first time. Although generally, I lhink the Mychart summaries are often less than fabulous.

  • Apr 08, 2019

    Extremely helpful, knowledgeable, very personable professional great experience.

  • Apr 06, 2019

    Spent time and did not rush through the appointment. Listened to my concerns and was very encouraging even though he was referring me jin to tother doctor.

  • Apr 05, 2019

    Dr. Ortega is always helpful, explains things so I can understand. Does not rush through appointments and his attention to detail is excellent.

  • Mar 27, 2019

    Both the Doctor & his assistant were emotionally up showing real concern about helping me & updating my Daavlin home phototherapy machine.

  • Mar 27, 2019

    I have nothing but good things to say. I have been able to address all the concerns I have and have been presented with solutions from my providers. I move quickly through the wait and appointment and even labs when deemed necessary. They are efficient and caring.

  • Mar 26, 2019

    Very nice. He told me how to take better care of my skin that no other doc did. I look forward to my 6 month check-up for basil cell carc.

  • Mar 22, 2019

    Let me just say that Dr. Ortega is the only Dr. I have found in almost 20 years that has thought outside the box and found a path to help me heal. His enthusiasm has allowed me to let him try various approaches that have been successful. His bed side manner is always positive and he listens to my opinions and personal needs. I also appreciate the respect he shows the nurses he works with. He is a credit to a University hospital with his continuous desire to not only teach but learn.

  • Mar 21, 2019

    He is a doctor that makes you feel comfortable & able to ask questions. He has listened to me and I am happy with him! Great doc!
