Brought micro plasma to his attention never followed up
January 30, 2017
He listens he pays attention to my charts and history. Found something that was making me sick and is helping me work on it.. One of the best PIH doctors I have seen so far besides my ob/gyn
January 24, 2017
PIH is horrible and makes their doctors over schedule patients so if you get an appointment in the afternoon be prepared to wait over an hour to see the doctor.

That Dr. Gastellum knows what he is talking about and explains the why of his recommendations. I know this because i also do my research for myself and he is on the dot on everything so far.

Dr Gastelum is very patient and tries to work with you as far as any questions or concerns about insulin, meters ,pumps .insurance etc.
November 21, 2016
Doctor says time is of the essence with a diagnosis, refers you to a second doctor. Second doctor tries to order MRI which you have already told first and second doctor you cannot have because of defibulator/pacemaker and now settles to cat scan. You take and 10 days later you are still waiting for results. First doctor now wonders why you are back to see him and says to hasn't talked to second doctor. Second doctor still hasn't called to disscuss. Feels like nobody is taking care of medical issue. First doctor, who you have begged for an appt says he can't see catscan, only notes, so he will talk to second doctor. Second doctor doesn't call back. What are you to do. Beg the first doctor again, or beg the second doctor. Or just give up and try other doctors somewhere else. Very, very disappointing when you are told treatment quickly is critical and now nobody wants to talk to you about what that treatment is or if there even is a treatment.

Gastelum is excellent
November 08, 2016
I believe he is an excellent doctor. He has a couple of Physician's Assistants (PAs) who work for him, and patients are rotated between the doctor and the PAs. As long as I see the doctor at least once per year or whenever I need to see him, I have no problem with this arrangement.
November 03, 2016

May 18, 2016
Dr. Gastellum is hands down one of THE BEST Endochronologists I have EVER worked with in the 24 years I have been facing the challenges of Type 1 Diabetes. In just the very short period of being under his care, my HAIC has dropped from an average of 10-5-13% to an average of 7.9-8.2%, which has made a significant impact on my overall quality of life experience. He does an EXCELLENT job each and every visit to make sure I not only thoroughly understand my condition but that I am actively involved in the decision making and maintenance of changes in my care. I have and would recommend him to anyone with the Type 1 Diabetes that I know! I truly appreciate his care and the courtesy of all the front office and nursing staff that assist him. I never feel like just a patient number when attending visits. All of his staff address me by name and interact with me in such a manner that makes me feel that their follow up in my care is personalized and customized based on my individual needs. :)
