Dr. Sistos is the BEST Doctor. He works for Kaiser Permanente in the Glendale Office. I selected him as my father’s doctor. He speaks Spanish and English, of course, fluently. I have sat through multiple doctor visits with him and my father. He genuinely cares about his patient’s health. He explains things well. He has this calm kind demeanor. He doesn’t just write you a prescription and send you away. He listens and asks questions as he tries to figure out how to improve your health. In addition, the Kaiser Glendale office is great because it’s smaller and it has a lab, pharmacy, and parking on site. The nurses are also really kind and friendly.
