That Dr. Gastelum was very professional.
January 30, 2018
Everyone was very nice and attentive, my first time here, I was kinda of afraid of coming, for this issue, but the doctor was very friendly, and asked me questions, which I answered, he made me feel very comfortable. Which was helpful, and he didn't wear a white coat, like many people I have a fear of the white coat. It was a nice experience with someone I had never met before. Thank you, Dr. Christian Gastelum.

Getting into see Dr. Gastelum takes a long wait time for the appointment, but the wait it ABSOLUTELY worth the wait.
December 12, 2017
I got the apt time I wanted, I was taken back to the exam room on time. the physician took time to talk, show me lab results, discuss medications. At all times, I was considered a partner in my care and treatment and that feels terrific
November 28, 2017
He was a great provider and explained things thoroughly. The only issue I had was that it took over 2 months to get to see him. He had a very long wait time for appointments. Other than that, it was a great experience.
November 14, 2017
Dr. Gastelum always talks to me about my blood work done the week before the appointment. If he sees something not normal he will tell what to do to fix it. He introduces new medicine to me that will benefit me for my diabetes. I have been his patient for over 5 years and I will continue to go to him!!!

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.

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.
