My past experiences with endocrinologists have not been good, as they tend to only look at labs and #'s. Dr. Gastelum is amazing, very caring, listens, always has a solution or willing to try different things and support his patients. Truly blessed to have him as my Dr. Thank you Dr. Gastelum!

Great doctor and very knowledgeable
April 26, 2017
Like I mentioned in my last comment, Dr. Gastelum is great! By far my favorite doctor. I have raved about him and now my mom, older sister and daughter also see Dr. Gastelum and love him as well... and he speaks Spanish which is a plus because my mom primarily speaks Spanish. The waiting is never long, he always listens to all questions and concerns, answers everything clearly and I absolutely trust him. He takes great care of the females I love the most- my daughter, my mom and my sister.
April 25, 2017
He didn't seem in rush as other doctors frequently are, and made a point of explaining in great detail everything he recommended. I think I am in good hands....will give feedback in a year.
April 18, 2017

He is Great! Spends the time you need to go over questions
March 09, 2017
I liked Dr. Gastelum very much. He's very friendly and knowledgeable and I would recommend his services to friends and family, but it does take a while to get an appointment. He did call me back the very same day as the appointment when I had a question for him which I liked.
January 30, 2017
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.
January 20, 2017
Like this provider very much
January 17, 2017

December 05, 2016
Just be more on time with appointment.
December 02, 2016
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.
November 30, 2016
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.
November 08, 2016
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
Provider great. PA in whittier office good, but communication with patient needs some work. Front office staff at both offices friendly and very professional and compassionate with my concerns
October 25, 2016

October 10, 2016

August 18, 2016
First visit required a long wait time. Dr. Gastelum covers a lot of information and seems to have a good handle on what is going on with me and what is needed. Very thorough explaining conditions and how we are going to fix my health issues.
July 12, 2016
if you need a Diabetic dr Gastelum is the one to check you out

I feel Dr. Gastelum does a good job. HE is not always available unless you have an appointment, but you can generally talk with some other doctor in his office. i have Addison's Disease, so my healthcare is a difficult one.
