Patient Comments (5)
in Issaquah, WA |
I have been diabetic for over 30 years. I am now 79. I have had many, many doctors. Dr. Mercado gave me a real caring doctor. She is very pleasant, understanding, and treats me like I am her only patient. I have never felt before a real relationship with a doctor who understands diabetes so well and who understands her patient's worries. I feel I have the best care possible!
in Tacoma, WA |
Dr. Maria Mercado is an excellent physician and has helped me to get my diabetes more manageable. She has empathy and cares about the person. She always takes time to answer any questions I have and listens to what I have to say. She communicates well in simple terms that I understand. I couldn't be happier with my care and would highly recommend Dr. Mercado to others.
Bellevue, WA |
Dr. Mercado does give you her full attention and answers questions patiently and fully. Getting hold of her can be difficult, however.
in Kirkland, WA |
Dr. Mercado is warm, friendly and extremely knowledgeable. After feeling like there wasn't a decent endocrinologist on the eastside, she was recommended by my primary care doctor and I couldn't be happier. She is thorough, does not rush you through your appointment, and her office staff is wonderful. I recommend her highly and have already referred several friends to her.
Redmond, WA |
Dr. Mercado was disrespectful and inappropriate. She demonstrated a basic lack of clinical analysis and standard decorum. Her behavior was so inappropriate that I reported her to management.
