    I'm glad that Alex Ortega was very kind to me and very down to earth and very respectful. And I actually gave me a lot of time to talk to him. I appreciate everything he did and I appreciate him diagnosing and trying to get things accomplished and a good way and making me feel like a human being instead of like. Sorry, babe. So I would appreciate that and I appreciate everything that he pulled me and talk to me about. He really is a winter in my book? He's a really good doctor. Thank you so much. Appreciate it. Bye.

  • Sep 23, 2019

    I find Dr. Ortega to be a very caring and wonderful man. He has helped me greatly and after years of having problems he is the one who has made the most different. I find him to be exemplary in his position and I also work with him in wound care and I just think he's fabulous and I won't see anybody else but he him if he leaves OHSU I will follow him wherever he goes.

  • Sep 21, 2019

    Always have had competent and compassionate care.

  • Sep 21, 2019

    Yes, he a is very good doctor.

  • Sep 19, 2019

    Kinda quick amd i had no time to think of follow up questions to his diagnoses. Like is there a PH test i can take to prove the docs theory is correct. I take a probiotic daily as well as eat yogurt with lots of probiotics. So i am suppose to trust the doc who is practicing his medicine on me with no data to back up his resolution.

  • Sep 18, 2019

    They are always helpful, understanding and the hear my concerns and talk to me in a way I can understand what they are doing and what is happening to me.

He is not like medical, the medical world is in the United [Name] right now. He is very caring, and not worried about the money, or the number of people he gets through his office, and how quickly.

I enjoyed enjoyed the experience actually of seeing them both. So now I would give them a very high rating both Dr. Loayza and Dr. Bolton, so I think you for your time and bye.

  • Sep 05, 2019

    It is a great benefit to be treated by doctors whose income is not dependent on pushing any particular treatment plan.

  • Sep 03, 2019

    The process was smooth and wait time was very good as they got me right in. Staff was friendly and was very efficinet to go get labs and x-rays done right there with very little wait.

  • Aug 31, 2019

    This is very very awesome provider would recommend him to anybody. He's very patient and very understanding and no one is filled and we thank you very much.

  • Aug 31, 2019

    It was good. All staff were friendly and professional.

  • Aug 31, 2019

    Dr. Ortega is a great doctor. He's friendly, knowledgeable and thorough.

  • Aug 29, 2019

    The provider was very wonderful, very helpful. However, I don't think he understood that I completely know nothing about the problem that I have, and to me he didn't explain it quite clearly enough to me. Not entirely his fault, because I didn't, probably didn't ask enough questions. Thank you.

  • Aug 26, 2019

    My provider is very good. He will understand the patient feeling very guilty. He will listen very patiently. He will check the alternative very quickly.

  • Aug 24, 2019

    Dr. Ortega has diagnosed me with two different types of skin cancer. He treats me for skin lesions that are precursors to skin cancer.

  • Aug 24, 2019

    Everything was fine, very perfect.

  • Aug 20, 2019

    Dr. Ortega is wonderful. He is calm and kind and very knowledgeable.

  • Aug 20, 2019

    He listened to me, heard what I said, consulted with my Rheumatologist while I was in the room so we were able to solve the medication problem while we were together. I was happy to get it taken care of rather than wait to solve the problem.

  • Aug 15, 2019

    My experience with the doctor was very excellent because the doctor checked and explained my problem, and has taken a lot of care, and gives me results in the other time I am at an appointment with him, and the truth I am very happy with the results. Thanks. I congratulate you, goodbye.

  • Aug 06, 2019

    Dr. Ortega addressed each of my dermatological concerns and, where appropriate, dealt with the offending skin anomaly. I heartily recommend him.

  • Aug 06, 2019

    Dr. Ortega is direct and friendly.

  • Aug 06, 2019

    This provider is very personable, knowledgeable, and effective with his time. It did not take him long to asses the situation and to know what the diagnosis was. He was, however, not completely knowledgeable of my health history and the fact that I have an auto immune disorder. He advised me to get an over the counter product for treatment and was very available for multiple phone follow-ups via his assistant. He should have consulted with a good pharmacist to delve into causes of my symptoms. When I did, I found out that my situation is caused by one of the meds I am taking for another health condition.

  • Aug 06, 2019

    He is a very good doctor and he takes the time to listen to you and check out what you say. I am very happy with them. Thank you.

  • Aug 03, 2019

    prompt,personable,concerned,thorough. Explained treatment options and recommended follow up.

  • Aug 03, 2019

    I feel very fortunate to abe treated by Dr Ortega, and also enjoy meeting his Residents.

  • Aug 02, 2019

    Really cares and spends time explainingThe treatment Worth the wait

  • Aug 01, 2019

    My experience was very good, and I enjoy working with the doctor, Dr. Ortega and his assistant and think that they are competent and helpful in in a very difficult auto immune problem that I have. So I was very pleased with my visit. I appreciate that kind of care that I'm getting and rate the service very high. Thank you.

  • Aug 01, 2019

    He is extremely comforting, encouraging, empathetic and very very wise. He's very knowledgeable about the conditions in dermatology and internal medicine. I am extremely pleased with his care of me.

    The provider is friendly in a professional manner

  • Jul 20, 2019

    Hi, Dr. Ortega and his nurse - they were so... so involved with my my condition and they were you were so enjoyable to be around during that, that it really helped the experience to be... to be towards a really good, good experience. They were... they were smart and actually kind of humorous at times. Really, really nice, really nice. I enjoyed... enjoyed them a lot and Dr. Ortega is really great. So I thank you so much and bye for now.

  • Jul 18, 2019

    Dr. Ortega was wonderful. I would definitely recommend him. Only thing is today is Thursday, and on Monday I had sent an email through MyChart directly to him and I haven't gotten a response to my question that I emailed usually like I'm used to doctors getting back to me the same day or the next day. That's my only feedback and I have another appointment with him for the 12th, and I will definitely be there. Thank you. Goodbye.
