Patient Reviews

I still believe Senior Citizens should be seen in person. I understand why the Physicians can't too.
January 12, 2022
Dr. Gastelum's staff is very attentive and caring, and Dr. Gastelum himself is a very empathetic doctor and very up to date on the type of medicine that he does - the endocrinology - and his follow through is amazing. When he ordered lab or appointment, I always get information in the mail regarding that, and his staff is so helpful, and I would recommend anybody to see Dr. Gastelum.

Dr. Gastelum provided invaluable info that I wish I would have received years ago. He gave me lots of great information. He also gave me hope that I will be able to get my condition under control.

Thank you - both Dr. Gastelum and his office staff (namely, name removed and name removed) treated me like I was the most important patient there.... and I am aware that others feel the same way. Thank you!

Since I have started going with Dr. Gastelum I have felt better than I have ever felt going to my other doctor's. I wish there was a way where he could become my main doctor, instead of th,e other doctors. The other doctors have left me on medicines, for years instead of helping me. It has destroyed my health. Dr. Gastelum listens to me and he has helped me greatly. I would recommend him to anyone or any family member. And I don't know what else I can say about him, I am very happy with Dr.Gastelum my health has improved with him.

Dr Gastélum is always very attentive and curteous
November 09, 2021
The situation is, it's impossible to get a phone call into the office. Sometimes, I have to call the other office, and then they connect me to Wittier office, and I waited on the phone for hours, trying to get an appointment, or to talk to somebody... And, I also think the communication between the doctor, and his nurses. It's not very good. He tells me one thing, and then something else is presented to me by the nurses. So there you go. Thank you.

Great Dr. Always knows about the latest and greatest medicines and treatments.
November 08, 2021
Dr Gastelum is amazingly knowledgeable and fantastic to deal with. I have never dealt with a doctor as wonderful as him
November 04, 2021
Ohh, yes. I think this office could really improve in the answering of the telephone. You know, in a timely matter... Most of the time I end up hanging up, or driving to the office because I cannot you know, get through. I mean, I wait too long. And I can take care of it, if I just drive over there, and come back. So if they would answer their phone in the in the staff, that answers the phone take care of your questions or problems that you're having with something. Either a prescription, or something that you need to pick up that, you told the doctor. The doctors great, but I just don't care for the answering.

Dr Gastelum is great. Not pushy and explains things in non-professional terms so it's understanding to the layman.
