Patient Reviews

I appreciated how Dr. Gastelum took the time to listen and answer all my questions thoroughly. I would certainly recommend him.

First visit was while in hospital. This was first appmt. At his office. He was very kind and I appreciated his manner and interest. He ordered labs to be done in the Bldg that day which I appreciated and did. No follow up appmt was made until he reviewed the results. Have not heard from his office as yet.

I've gone to three different endocrinologists. This doctor was recommended to me by a nurse at PIH Health with whom I've volunteered. While I believe he does a good job, he tends to shift his patients to his Physician's Assistant (P.A.) after seeing the patient the first time. Then the patient sees the doctor about once a year. I would like to have more access to the doctor. Otherwise, I'm reasonably happy with this provider.

My original appointment was to be over 4 months from my referral by my PC doctor. I questioned her about waiting that long and apparently she intervened and I was called by your office with an appointment in a few weeks.

The Doctors are knowledgeable and compassionate, helping the patients see how we can manage ourselves through a healthier lifestyle. This is a busy office and it is sometimes difficult for a new patient to get an appointment in a timely manner. However, once you are an established patient it is easier to get in to see a doctor as needed.
