I understand needing money and charging for parking but when there is a huge line to get out and elderly people do not understand how to use the machine this creates an unsafe situation. Not able to get out of a parking lot in a timely manner is wrong!

Dr. Gastelum was extremely helpful with my medication problem and he watches my blood levels very carefully to make sure I am receiving the correct dosage of the medication.

Having to pay for parking is really irritating! You should not have to pay for parking. There was a line at the kiosk to pay the parking fee, my hands were full of paperwork and medicine so it was a pain to try and pay.

I like a nurse to call me back to confirm that I'm supposed to stop my insulin. The doctor wrote me a note but is handwriting's not the best. I want to be sure I'm supposed to stop my insulin.

Excellent care from Dr Gastelum.
March 23, 2021
Great.
March 23, 2021
I am 100 percent beyond satisfied with Dr. Gastelum! However, his supporting staff definitely needs some training in their customer service skills! But for me, it's the doctor that is where my concerns have to take priority, and he's worth the trade off!
March 23, 2021
This was a great experience. I look forward to my next visit. Keep up the great work.

February 17, 2021
My issues aren't with Dr. Gastelum, my issues are with his staff. I continuously have problems with prescription refills/renewals. They do not respond to the pharmacy. When I call to inquire they put the responsibility on me and are of no assistance whatsoever. I have had this issue numerous times and it's very frustrating.
February 17, 2021
Dr. Gastelum is very thorough. I trust him 100%!
February 16, 2021
This was my first time with the doctor. I was very impressed with the office with the staff. The doctor gave me the time and attention that I needed. He explained everything. I was very happy and I hope I can continue to see him. Like I said, I was very impressed right from the start very impressed.

Dr Gastelum is an incredible doctor. I don't agree how PIH treats their employees
February 04, 2021
It was my first appointment with Dr. Gastelum. He was very attentive and we disused my medical concerns. He explained our plan to figure out the issue and what our next stops would be on different scenarios. He made me feel at ease. I was very happy with him and his staff.
February 03, 2021
Always feel well cared for.
February 02, 2021
I feel like Dr. Gastelum really listened to all of my concerns. It's been I've been trying to get my thyroid taken care of for years and everybody just said well, it's close to normal, and there was nothing that could be done and he is taking all the steps necessary to ensure that all of my problems are going to be alleviated I hope and but I for the first time I feel hopeful that I can get something done about the issues that I've been faced with. So, I really appreciate the fact that he listed so well, and he explained everything so thoroughly. Thank you.
January 29, 2021
It took me four days and ten attempts to get into the office. Also some of the information on the portal is incorrect and old. And it's impossible to talk with anyone to fix it. Dr. Gastelum is a fine doctor but the phone system and staff needs improvement. But I find this problem with all PIH facilities.
January 28, 2021
simply the best doctor and staff, would highly recommend. best attention and care, totally listens to you.
January 28, 2021
Excellent doctor.
January 27, 2021
The doctor is excellent. I never had a doctor that explained every little detail to you and compares to the last visit of my blood test. He's always been very good. The staff is always been very excellent. I am so happy to be with this doctor. That's why I never change my insurance because of him and the other doctor that you have on staff. I just want to thank you so much.
January 26, 2021
Was good. No waiting time was seen right away.
January 26, 2021
Really appreciated Gastelum taking the time to review all my lab results with me and discussing not just what is normal but what is optimal given my personal desires and wishes related to my health. I felt heard and understood. I was excited leaving the visit knowing that I had options that no other provider has discussed with me before.
